Posted by Waqas Anwar on 02 Mar 2012 - Views Count: 3877

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.

Almost all ASP.NET Web Applications require some sort of configuration settings to be stored in the web.config files. These settings can be application settings, database connection strings, user authentication settings, page specific settings and so on. ASP.NET also provides very powerful Configuration API to work with configuration settings defined in web.config files. The Configuration API not only allows us to read/write settings in configuration files with ease but also allow us to define our own custom configuration sections in web.config. These custom sections are very useful in large web applications where you have a lot of application settings to store in the configuration file. In this tutorial, I will show you how to create and use custom configuration sections in ASP.NET.
