Mixing C# & VB In The Same Project
Is it possible to write two applications using different .Net languages (For example C# and Visual Basic) and combine the two into a single program in Visual Studio?
I want to write two parts of one program in two different languages and merge them.
Thanks.
You would need to clarify what exactly you are after, but the .Net languages are more or less interchangeable. You could write one DLL or component in C#, and another in Vb.Net, and then use both in a parent application which could be in either language (or something different entirely).
