Question

I am using .NET4.0, but for compatability reasons, I’d like to compile to a .NET2.0 dll from c#. There should be no .NET4.0 specific functionality used in the script, so it should run fine in a .NET2.0 environment. Is there some commandline syntax on the csc that I can specify a version number with?

Answer 1

You mentioned csc.exe, so I’m assuming that you won’t be building with Visual Studio, but rather, by command line. Also, I’m assuming that msbuild is not available on the build machine.

I believe that csc.exe is specific to each version. For example, in the folder C:\WINDOWS\Microsoft.NET\Framework\v4.0.30319, you will find csc.exe, and in the folder C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727, you will find another version of csc.exe.

To build a .NET 2.0 dll, you should reference the csc.exe from the v2.0 folder (C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727).

Cheers!
