In the age of .NET managed code, it is very much painful to write code in Classic ASP. But you have to face such a situation for giving support in old classic ASP application where you cannot get .NET Framework facilities by default. In this post I want to explain how you get all .NET facilities in classic ASP pages. Here I will use C# as a .NET language.

Step for Get it Done

1. Lets consider you are working on the directory E:\work\rd
2. write a C#.NET application in the MyTest.cs file which will do a multiplication
3. Now add the following namespace into your program file MyTest.cs

   
   using System.EnterpriseServices;
   using System.Runtime.InteropServices;
   

4. Also add the following name space for strong key
   using System.Reflection; using System.Runtime.Co

    using System.Reflection; using System.Runtime.CompilerServices; 

   Add for following assembly information into the Mytest.cs. here MyClass is used as name u can give any name u want . [I will discuss about “key.snk” after completing the MyTest.cs]
   

   [assembly: ApplicationName("MyClass")]
   [assembly: ApplicationActivation(ActivationOption.Server)]
   [assembly: ApplicationAccessControl(false,AccessChecksLevel=
   AccessChecksLevelOption.ApplicationComponent)]
   [assembly: AssemblyKeyFile("key.snk")]
    
   
   

5. Now the write a method into your class with do multiplication operation

   namespace erpbd.Library
   {
       public class TestApp
       {
           public string Multiply(int x, int y)
           {
               return "The result is :" + (x * y); 
           }
       }
   } 
   
   
   

   complete code is given in “RD_CODES.zip”
6. SNK is a Strong name utility. We have to create a “key.snk”. consider that visual studio 2005 is installed in your pc go to start>all programs>Visual studio 2005>visual stdion command prompt . now go to your working direcrory then write the command sn –k key.snk [follow the snapshot]
   
7. Now you have to make dll file with the following command csc /target:library /out:ErpLib.DLL MyTest.cs ( if you got any warning then ingnore it )
8. Now you have to make a tlb file with the following command regasm "E:\work\rd\ErpLib.DLL" /tlb /codebase Step 7 and 8 is displayed in following snapshot
   
9. write a ASP page which will contain the flowing VBScript code

10. Now browser the ASP page from your browser then you will get the following output.
