1: Why would you want to? Is there a compelling reason to do so? If not, then don't.
2: Yes: Create 1 solution with 2 projects. One of the projects is a library of functionality created in C# or VB. The other is the main project created in C# or VB which references the functionality in the library.

Solution 3

Yes, it's possible. There used to be an example in SDK v1.1
called: CrossDevLanguage.

See here.

Solution 4

Yes, but it is bad practice.
Stick to one language.

You can write in both within a series of webpages and call routines in either language, but it is ugly and crude and should be avoided.

This is possible in ASP.NET because each page is loaded seperately, only for the page lifecycle. Your many pages are never compiled all at once. However, even in an ASP.NET project, your app code classes all need to be one or the other. The only way to get around that requirement in ASP.NET is the same way you get around it in a windows app. Your Windows app MUST be all VB.NET or all C#. However, it can load any .NET dlls you like, and they must also be ALL VB.NET OR all C#. In other words, your C# app can consume a VB.NET dll, and vice versa.
