I have a file called Asembly-CSharp.dll i want to edit in C#. I decompile it with .NET reflector's FileGenerator (also tried file disassembler and dotPeek) plugin, thus creating a visual studio project, i open it in visual studio, but it fails to build, i didn't change anything, yet i get lots of errors (like unexpected characters etc), the dll refers to lots of other dlls but even if i put all of them in one solution it fails. Why does it fail if i didn't change anything in the source code (.NET framewrok version is the same as it was before decompilation). Any help appreciated.
I tried both visual studio 2012 and 2013 (win7 but i know that shouldn't be the problem) I'm not professional, forgive me if i made some silly mistake.
