Is it possible to make calls to code in vb.net from code in c#?
yup
Yeah, that is pretty much the entire point of .NET.
If a namespace is used in c# then loaded, How could i use vb.net to reference those namespaces?
The same as any other library. You will not know which language it was written in, and will not care much.
wow , yeah easier then I thought. thanks.
