While using Visual Studio C# Express 2010, I’ve noticed a small problem; namespaces such as System.Windows and System.Drawing are missing, so where could I find them, or can I download them online?
P.S: I’ve opened the System reference and really got worried as I didn’t find those references.
The two assemblies you mentioned are available only for Windows applications. If you are creating a console application such assemblies are not even shown in the Add References.
