how to install win version of mono

How do I install the windows version of mono?
I get the message
"wine: Install the Windows version of Mono to run .NET executables"

mono is the linux-version of the .NET-framework. to make windows-applications that use the .NET-framework work in wine you have to install the windows-version of mono (=> the .NET-framework ) in wine.
try
sudo aptitude install mono-common
