Can I use different programming languages in ASP.NET site?
You can use different programming language for every page in ASP.NET web application. For example, one page could be coded in C#, second page written in VB.NET etc.
You can not use different languages in the same page. Complete page must be written in the same language. One language - one .aspx file.
All code inside App_Code folder must be written in one language. But, you can make sub folders inside App_Code folder and have different language in each folder
If you still use ASP.NET 1.1, all web application's code must be written in one language.
