Unraveling the Error: So, you're ready to run your website 🌐, but you hit a roadblock with the dreaded "Could not load type MvcApplication" error. This error occurs due to a mismatch between the name of your application's main class and the configuration in your web.config file. Let's break it down further!

Common Issues: 🔍 Issue 1: Missing or Misnamed Global.asax.cs File The global.asax.cs file is the backbone of your MVC application, and any discrepancies can lead to the error. Verify that the file exists in your project's root folder. Additionally, ensure the class declaration matches the configuration in the web.config file.

🔍 Issue 2: Incorrect Web.Config Configuration The web.config file contains essential settings for your application. Double-check if the TypeName attribute in the httpApplication section matches the fully qualified name of your MvcApplication class. Typos and differences in casing can cause this error. Don't forget to save the changes!

Easy Solutions: 💡 Solution 1: Rename the Main Class Assuming you have the correct global.asax.cs file, navigate to the class declaration and make sure it matches the name mentioned in the web.config file. Ensure the capitalization, spelling, and any namespaces are precise. Save your changes and recompile.

💡 Solution 2: Update the Web.Config Open the web.config file and search for the <httpHandlers> section. Locate the <add verb="*" path="*.aspx" type="MvcApplication"/> entry. Replace MvcApplication with the fully qualified namespace of your main class, such as MyProject.MyNamespace.MvcApplication. Save the file and restart your application.
