How to Compile an EXE file with ASP.NET (server side) ondemand

You can build the .NET source code dynamically and compile it on server side without problems
For that you can use one of CodeDomProvider classes example CSharpCodeProvider or VBCodeProvider fill the CompilerParameters structure and call CompileAssemblyFromSource

_codeProvider.CompileAssemblyFromSource(compilerParams, sCode);

Another way you can have signature in a exe file append that signature to exe and after append additional data (example torrent info) and once exe starting you open that exe for reading find the signature and after read you private information for your exe and use that inside your program.
