CheapASPNETHostingReview.com | Best and cheap ASP.NET Core 1.0 hosting. In this post I will explains about ASP.NET, and why ASP.NET is the best hosting for us.
What is ASP.Net Web Hosting?
ASP.NETweb hosting is basically a hosting solution to run websites that are developed by the Microsoft ASP.NET technology and databases. Although Mono provides the capability to host ASP.NET applications on Apache web servers in Linux, it is not recommended as ASP.NET is technically based on Windows server platforms. This is because when you run websites on Microsoft platforms or using Microsoft technology, the reliability and performance are guaranteed.
ASP.NET helps in creating Web applications with relative ease and with fairly less coding. ASP.NET is a group of technologies based in the Microsoft .NET Framework to build XML Web services and Web applications. But there is more to ASP.NET than just that. ASP.NET pages perform on the server and create markup such as HTML, XML, or WML which is then sent to a browser. Unlike traditional ASP that only supports interpreted JScript and VBScript, ASP.NET can support many .NET languages (this includes built-in support for C#, JScript.Net, and VB.NET). This provides greater flexibility in choosing languages. To choose the best ASP.NET hosting look for these 5 features based on the ASP.NET:
Frameworks
Databases
Microsoft control libraries

What to Look For in the Best ASP.NET Hosting
As we mentioned earlier, the best ASP.NET hosting will feature five criterions. These points determine the ratings for ASP.NET web hosting.
[wp-svg-icons icon=”tags” wrap=”i”] ASP.NET Frameworks: Since ASP.NET websites require running in the associated .NET framework, it is always better when the web host is able to support most frameworks from v1.1 up to v4.0. In such a case, you can have maximum flexibility for your websites and can keep the possibility of upgrading to the higher versions at the same time.
[wp-svg-icons icon=”tags” wrap=”i”] ASP.NET Trust Level: It is basically the configuration in the IIS for a website. The best available and flexible option is to choose ‘Full Trust’. From then, you don’t have to worry about the websites not running properly in a shared web host. If you are looking for a balanced option between flexibility and security, then you can choose ‘Medium’ if you have the experience on debugging and deploying ASP.NET. You can also choose this when you are perceptive on the server reliability and security.
[wp-svg-icons icon=”tags” wrap=”i”] Add-on Features: Add-on features are basically third party applications. Installation is required for these third party libraries. They are very important if your website relies on Atlas library and E.G. Chat controls library among others.
[wp-svg-icons icon=”tags” wrap=”i”] Database: if you are concerned more on the supported SQL Server versions and its limitations, then the preferred SQL Server is 2008. However, many of the web hosts only support Express editions. It’s usually enough for most websites that are hosted with shared web hosting.
[wp-svg-icons icon=”tags” wrap=”i”] Knowledge of Microsoft Technology Support: Whenever in doubt, you can always call the technical support of your web host easily and ask the technical questions that are related to ASP.NET website configuration and deployment. This is very important especially considering if you have a problem in the future.
CheapASPNETHostingReview.com | Best and Cheap ASP.NET MVC hosting. ASP.NET MVC is a framework that adds support for the MVC design pattern to ASP.NET. Therefore, in order to really understand what ASP.NET MVC is, you need to first understand what MVC is. MVC is an acronym that stands for Model / View / Controller. MVC is a programming architecture that aids developers with separating different components of an application. Let’s review each component of MVC individually as they relate to ASP.NET MVC.
The Model
The model in an MVC application stores the application data or state of the application. The model is often a database, an XML file, etc. However, because the model is designed to encapsulate the data layer in the application, you will typically not see the data source correlated with the model with regards to MVC.
In an ASP.NET MVC application, the model typically uses LINQ to SQL or LINQ to Entities.
The View
The view is the user interface that your site visitors to see data from your model. In an ASP.NET MVC application, web forms (ASPX pages) are typically used to display the view, but there’s a significant difference between an MVC view’s page and a typical ASP.NET web form. Most specifically, an MVC view doesn’t use the typical postback model and the page lifecycle that you are used to when using web forms doesn’t exist with MVC views.
More Info You don’t have to use ASP.NET web forms as the view engine for MVC. Check out MVC Contrib on CodePlex for more information.
It’s easy to make the mistake of thinking of the view as the component in MVC that handles user input and controls the interaction with the user. In fact, it’s the controller that takes on this role. The view is strictly limited to displaying data from the model.
The Controller
The controller is responsible for handling the interaction with the user, for communicating with the model, and for determining which view to display to the user. The controller is derived from System.Web.Mvc.Controller.
The controller defines one or more actions that can be invoked using a URL entered into a web browser. For example, consider the following URL:
http://www.mysite.com/products/display/43
A request such as this one would be handed off to the ProductsController where the display action would be invoked. In this particular case, that action might then display a view of product number 43. The routing of the URL to a particular controller is configured using routes that are defined in the global.asax of the MVC application.
In order to maintain state in an ASP.NET web forms application, ASP.NET uses encoded data in a hidden form field via a feature called viewstate. Viewstate does pretty well at providing the illusion of a stateful application, but there are times when problems are encountered. For example, in large applications, viewstate can become very large. Large viewstate not only increases your payload across the network, but it can also impact your search engine ranking by pushing readable page content far down in the rendered code.
More Info
The problem of large viewstate was greatly improved in ASP.NET 2.0, and you can expect even more improvements in ASP.NET 4.0.
ASP.NET web forms developers also have to take the page lifecycle into account, and dealing with when to do certain things can be as much or more frustrating than figuring out how to do something. MVC does away with this kind of frustration because it is truly stateless. Postbacks and the web forms page lifecycle no longer exist.
Another advantage when using MVC is that it allows for full control over the rendered HTML. In a web forms application, HTML code is rendered in large part by server controls, and developers have relatively little control over the code that is generated. The HTML code in an MVC view, on the other hand, is entirely controlled by the developer of the view.
MVC also lends itself well to a separated approach to development. One developer can work on the controller class while another developer works on the view. This design methodology also aids in testing. It’s extremely difficult to test one particular piece of a web forms application because of the reliance of all of the other controls on the page and the managed runtime. An MVC application can be tested much more easily and efficiently because the model, the view, and the controller are all separate components.
MVC or Web Forms?
Now that you’ve got a basic understanding of what ASP.NET MVC is and what it offers, you may be wondering if MVC is the way to go with your future ASP.NET applications. Let’s look at a few scenarios that might help you decide if MVC is right for your next ASP.NET project.
Choose MVC if . . .
You are well-versed in the architecture of MVC. If you aren’t comfortable with how to design a controller, MVC probably isn’t a good choice.
You want full control over the HTML that is rendered in the browser and you can afford the development time and overhead to do all of your own markup.
You need to create efficient unit tests for your user interface without the overhead of the entire managed runtime, etc.
You want full control over how your URLs are formed.
Choose web forms if . . .
You are not familiar with designing MVC applications.
You need to minimize development time.
You want a feature-rich user-interface (such as GridViews, etc.) to display data with rich interaction without substantial development investment.
You are already invested in server controls, either from your own development or from 3rd parties.
These are just a few of the reasons why you might choose one framework over another. Obviously, no one can tell you what decision to make for your application. Ultimately, the decision is up to you, but hopefully the information I’ve provided here (along with some good links) will help you to decide as you approach your next project.
CheapASPNETHostingReview.com | Best and cheap ASP.NET Hosting. Today In this post I will explains the difference between the Classic ASP and ASP.Net and also focuses on the new features in ASP.NET. Let’s discuss the differences between these two in detail:
Process Isolation
ASP is running under the inetinfo.exe (IIS) process space and hence susceptible to application crashes due to that the IIS needs to be stopped or restarted. ASP is related to the process isolation setting in IIS. Where as, ASP.Net process is separate from inetinfo.exe (IIS process). Though the entry point into a ASP.Net application is still IIS but it is not related to the IIS process isolation settings.
Non-MS Platform Support
Classical ASP has no mechanism of running itself on non- Microsoft technology platforms like the “The Apache Web Server” (there are some third party products, like ChiliSoft) but, ASP.NET could be run on non- Microsoft Platforms also. Cassini is a sample Web server produced by Microsoft which, among other projects, has been used to host ASP.NET with Apache.
Multi Language Support in WebPage
Only VBScript and Javascript were available for scripting in ASP where as, in ASP.NET there are no such restrictions. The .NET compliant language can be used with ASP.NET including several like C# and VB.NET, where both of them are server-sided languages.
Interpretation Vs Compilation
In ASP, an interpreter like Jscript or VBScript is used to execute the server-side code. When an ASP page is requested, the text of that page is parsed linearly. The content that is not server-side script is passed back as it is to the response. Where as, the server-side script in the page is executed through the appropriate interpreter, and the output is then submitted back to the response. The efficiency of page rendering is affected by this architecture in several ways. Firstly, on the go interpreting of the server-side script. A common optimization for the ASP applications for this side affect is to move a mass of server-side script into precompiled COM components to improve the response time. Secondly, the intermingling server-side evaluation blocks with static HTML is another efficiency concern. It is less efficient than the evaluating a single server-side blocks because the interpreter has to be invoked time and again.
As a rescue, many ASP developers resort to large blocks of server-side script for replacing static HTML elements with Response.Write() invocations instead. Eventually, this ASP model permits the inclusion of different blocks of scripts within a page to be written in different script languages. This may appeal in some ways but it also reduces performance by requiring that a particular page load both scripting engines to process a request that consumes more time and memory if compared to just using one language.
But in ASP.NET, the pages are always compiled into .Net classes housed within assemblies. This class includes both the server-side code and static HTML, so when the page is accessed for the first time, subsequent rendering of that page is serviced by executing the compiled code. All the inefficiencies of the scripting model of traditional ASP are eliminated by this. No longer had any performance difference between compiled components and server-side code embedded within a page observed. Both of them are compiled assemblies now. Also, no performance difference between interspersing server-side code blocks among static HTML elements and writing large blocks of server side code and using Response.Write() for static HTML content. The .aspx file is parsed into a single code file and compiled, its not possible to use multiple
This eliminates all the inefficiencies of the scripting model of traditional ASP. There is no longer any performance difference between compiled components and server-side code embedded within a page they are now both compiled components. There is also no performance difference between interspersing server-side code blocks among static HTML elements, and writing large blocks of server-side code and using Response.Write() for static HTML content. Also, because the .aspx file is parsed into a single code file and compiled, it is not possible to use multiple server-side languages within a single .aspx file.
Debugging benefits
In classic ASP, debugging is a tough task because of limited support due to the interpreted model. In contrast, not only ASP.NET improves the performance over the interpreted model but also provides debugging tools for component developers and pages compiled into classes. The page errors are generated as compiled errors and there is a fir chance that most of them will be discovered at the compilation time instead of runtime due to the fact that VB.Net and C# are strongly typed languages. In addition to this, the tools available to the Windows Forms .Net developer are applicable to the ASP.NET developer.
Server-Side code placement Web Page
In ASP pages you might include the executable code outside the scope of a function within a script block marked as “runat=server” and you may also define a function within a pair of server side script tags. Where as in ASP.Net the former is no longer supported and the latter is also not possible.
A default constructor is provided by the generated class definition, and it would be a compiler error if you try to write a default constructor. For this, you can choose the alternative method of separating the layout from the page logic which consequently gives you a complete control over the class definition. This method is called code-behind.
Deployment Strategies
The components used by pages and deployed in this manner were difficult to update or replace in the Classic ASP. You are required to shutdown the IIS because of the fact that while the application was functioning, it referred to the component file for replacement. So, after taking your web server temporarily offline, you had to replace the file and then restart IIS. But, in ASP.NET it aimed to get rid of the need to stop the functioning Web application whenever the components needed to be updated or replaced.
To attain this, the designers of ASP.NET had to ensure two things: first, that the running application not hold a reference to the component file and second, that whenever the component file was replaced with a new version, that new version was picked up with any subsequent requests made to the application. Both of these goals are achieved by using the shadow copy mechanism provided by the Common Language Runtime (CLR).
New Page Directives
In ASP, the directives are required to be placed on the first line of a page within the same delimiting block. For instance:
1
<%LANGUAGE="VBSCRIPT"CODEPAGE="932"%>
While ASP.NET required you to place the Language directive with a Page directive, as follows:
It could be more than one directive lines, which depends on your need. The standard practice is to place the directives in the beginning of the file but you can place it anywhere in your .aspx file.
Threading Issues
The threading model of COM object created using VB within a web-based application is STA (Single Threaded Apartment). ASP worker thread resides in its own STA and hence the compatibility is fine in this case with a little performance hit.
But in ASP.NET, threading model is the Multiple Threaded Apartment (MTA). This means that components that you are using were created for the Single Threaded Apartment (STA) will no longer perform or function reliably without taking some extra precautions in ASP.NET. This includes, but is not limited to, all COM components that have been created using Visual Basic 6.0 and earlier versions. You will be glad to hear that you can still use these STA components without having to change any code. What you need to do is include the compatibility attribute aspcompat=true in a <%@Page> tag on the ASP.NET page. For example, <%@Page aspcompat=true Language=VB%>. Using this attribute will force your page to execute in STA mode, thus ensuring your component will continue to function correctly. If you attempt to use an STA component without specifying this tag, the run time will throw an exception. Setting this attribute to true will also allow your page to call COM+ 1.0 components that require access to the unmanaged ASP built-in objects. These are accessible via the ObjectContext object. If you set this tag to true, your performance will degrade slightly.
Validation & Browser scripting capabilities
There is no inbuilt facility for the validation of controls in the Classic ASP. For example, checking whether a textbox is left blank, or a combo is selected or not, or if a phone number does not fit a particular pattern for area etc.
These kinds of validations required the user to write the client side Javascript code.
It was not less than a headache for the developer to cater the client and server side validations.
What added to the burden on the developer was the Javascript code to fit a particular Browser. Specific code had to be written to fit a set of browsers and it consumed a lot of time.
But in ASP.NET, In built validation controls are provided which are easy to implement and the developer has to worry the least.
The features provided by ASP.NET validation controls:
Browser Independent coding: Developer does not have to worry about the browser and how controls would render to.
Client-Side or Server-Side: The Validation Controls manage the code checking if the client side code is disabled the validation is done on the server side.
Rich Validation set
There are few types of validation which cater to the needs of the validation requirements:
RequiredFieldValidation Control – Requires that the control not be left blank.
CompareValidator Control – Used to compare Data in Two Controls
RangeValidator Control – Used to check for Range validation (also supports various data Types – Date, string etc…)
RegularExpressionValidator Control – Used to check the complicated patterns in the user input.
CustomValidator Control – The final control we have included in ASP.NET is one that adds great flexibility to our validation abilities. We have a custom validator where we get to write out own functions and pass the control value to this function.
This control also provides Client side and server side validation of which the Server side validation could be a different function altogether.
Validation Summary
The validation summary control will collect all the error messages of all the non-valid controls and put them in a tidy list. The list can be either shown on the web page (as shown in the example above) or with a popup box.
Conclusion
Classic ASP goes a long way toward simplifying Web programming. It is demanding when it comes to writing a new DDL from the very beginning as compared with the easier task to write some HTML and mingle it with a script. But then Classic ASP is not fee of issues. The ASP pages are mass of unstructured code. It can be compared to the early days of BASIC programming, where achieving a task quickly was possible but the resultant code was often hard to follow. The object model of ASP has multiple inherent or global objects. For instance, for the generation of the content of an HTTP request, script code is written and the content is send to the client using the intrinsic Response object. In the guaranteed situations where only one client is involved in talking to your Web application, this isn’t much of a problem. But not many web applications guarantee this. And the reason for this is the way ASP is organized by these intrinsic objects.
ASP.Net improves the classic ASP. The same intrinsic objects still remain in ASP.Net and the scripting can be added anywhere on the page per you requirement. In fact, ASP.NET easily manages and runs most of the ASP pages with .aspx extension.
ASP.Net introduces a lot of new features. Like all the components within .Net, ASP.Net pages too are compiled into the assemblies, which give a performance and security edge. Further, it supports the usage of any .Net language. This means there is no restriction over the use of JavaScript or VB Script on your Web pages. Now, you have an option to use more structured languages.
ASP.Net opens up a whole new programming model with the blend and combination of Web forms, server-side controls, data binding, and Web services.
