Using Multiple Programming Languages in ASP.NET Website

ASP.NET websites do not allow you to use multiple programming languages such as C# and Visual Basic in the App_Code folder of the website project. If you are creating a C# web site and you have copied a Visual Basic source file in App_Code folder, you won’t be able to compile your ASP.NET website. Off course, if it is a small source file, then you can convert it into C# source code either yourself or by using any code converter but it is time wasting practice if you have a large file or you want to use multiple source files. In this tutorial, I will show you how you can use multiple programming languages source files in a single website project by just doing some simple modifications in the configuration settings of the website.
