Decompile a .Net Executable and Rebuild it in C# / C++ etc.

Have a executable which is based on the Microsoft .Net Framework 4.0.

I can decompile the executable in Reflector. This gives the program structure, dependencies etc. and also decompiles the program in C# program language.

So need to have it rebuilt in Visual Studio so I can easily modify it instead of working with assembly language.

As the C# is available 90% of the work is done, needs to be restructured and syntax modified accordingly and debugged.

The program file is 2.5MB in size.
