Hello, nice to meet you on freelancer website.
I have ever done a similar project but different, that project is to convert source code from C# to VB.NET, the best way to do this I think is:
1, Build the application in VB.NET to generate assembly: EXE or DLL
2, Use .NET Reflector to reverse the DLL to see C# code
3, Export C# code from .NET Reflector
4, Open the exported projects in Visual Studio, fix syntax errors, add comments if necessary, test the program to see whether it works good.
I use:
Windows 10 OS
Visual Studio 2015
SQL Server 2012
.NET Reflector (I forgot the version)
Let's start work on it, thank you!
