I need to compile a class library (DLL) from an ASP.NET source. Now when I try to build it says this:
The type 'System.ComponentModel.ISupportInitialize' is defined in an assembly that is not referenced. You must add a reference to assembly 'System, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089'.
Now I know that I have to put it in the web.config file. But there is no web.config file it's just the source of the dll that needs to be compiled.
How can I do this?
