Why upgrade?

The upgrade to an ASP to .NET conversion is a substantial step any way you look at it. There are important decisions to be made and to avoid difficulties. It is essential to have a perfect plan based on available knowledge.

ASP.NET is the new era development platform to build enterprise Web Applications. There is not plenty of differences between ASP and  ASP.NET.

The significant steps involved are emigrated to ASP.NET, implementing Web services, and making the new VB.NET user interface.

ASP to .NET emergence can be performed with tools but, as these two environments are different, this method is not sufficient. Working on the new features in ASP.NET will help in understanding the framework and analyze how the business will fit into it.

In an ASP to .NET conversion, the ASP.NET framework is very much different from unstructured ASP, and there is no right way to convert it into ASP.NET pages. If we want to make an ASP to .NET conversion, then one has to remodel it and code almost all the pages again, the most important reasons why one would do this.

• NET supports object-oriented languages such as C# or VB.NET when compared to ASP, which supports only scripting languages like VB Script or JavaScript. As ASP uses VBScript when an ASP page is executed, it gets interpreted. For ASP.NET, since it uses .NET language, it is compiled to Microsoft Intermediate Language.
• NET helps you maximize the ability of Event-based programming and introduced server controls that provide an advantage over Classic ASP.
• ASP has code and HTML mixed, but ASP.NET provides separation to code and HTML sections. In ASP, it is tough to reuse code unless it is placed in separate files, whereas ASP.NET allows for real separation of code and content.
• Developers came up with ways to transform classic ASP to .NET, a one-step conversion to the .NET environment will need your code to work in an existing ASP environment.
• In ASP, there is no in-built support for XML, whereas ASP.NET has full XML support for secure data exchange.
• Classic ASP has less development and debugging tools, so it is very tough to debug applications. In ASP.NET, various tools and compilers are present, including Microsoft Visual Studio that makes debugging so much easy.
• In classic ASP, when a code is inserted, the server needs to be restarted to show that change on the existing page. In ASP.NET, it has state management support which maintains state and page information over multiple requests for the pages.

Now, session sharing between ASP and ASP.NET is another requirement, but you will be stuck in with issues.

So, it’s essential to frame the right solution based on your current code that suits the transformation requirements.
A few times, partial porting may be the solution, or we have to find another way .NET code to a COM object that can be used by ASP code. Come up with a perfect transformation plan that will help to develop new features to legacy code.
