[Solved] How to use C# class in VB.Net Windows Application Project

Dear Sir,

I would like to know, can we maintain vb and C# both classes in same project(Web/Windows)

And how to call method of C# class into Vb.net class and vise versa in the same project(Web/Windows)

Case is that we have a old Web project with vb.net language and we want to implment new features with C# in our projects.

I appriciate your efforts

Thanks in Advance
