How use System.Windows.Forms, Version=2.0.0.0 in a .net framework 4.0 based application?

Question

in VS2010 write this code and run:

===========

string path = Path.Combine(Environment.GetFolderPath(Environment.SpecialFolder.Windows), @"Microsoft.NET\Framework");
string pathV2 = Path.Combine(path, "v2.0.50727");
Assembly assembly = Assembly.Load(File.ReadAllBytes(Path.Combine(pathV2,  System.Windows.Forms.dll")));
Console.Write(assembly.Location); 

================= it will write out: C:\Windows\Microsoft.Net\assembly\GAC_MSIL\System.Windows.Forms\v4.0_4.0.0.0__b77a5c561934e089\System.Windows.Forms.dll

so, how can I use System.Windows.Forms, Version=2.0.0.0?

thanks

Answer 1

Why don't you just target .NET 3.5 SP1 (which uses the only System.Windows.Forms assembly)?

Or, if you're going to target .NET 4, then why are you trying to not target .NET 4?

Edit 2: This isn't possible without creating a second assembly that targets .NET 3.5 or earlier.
