What are the methods for troubleshooting System.TypeLoadException errors in .NET?

edit

Check the .NET Framework version: Ensure that the required .NET Framework version is installed on the machine, and the application is pointing to it.

Check Assembly References: Check if all the required assemblies are present in the appropriate folders or locations.

Check Corrupted Assembly: Verify that the assembly is not corrupted. If the assembly is signed, the signature may be invalid.

Check Target Platform: Verify that the target platform (x86 or x64) matches the architecture of the assembly.

Check Assembly Name: Ensure that the assembly name matches the one specified in the code.

Check Dependencies: Verify if any dependencies are missing from the application or if they are present in the correct location.

Check Environment Variables: Ensure that the environment variables are set correctly and perform a clean build of the application.

Check GAC: Check if the assembly is present in the Global Assembly Cache (GAC).

Check Culture Settings: Check if the culture (language setting) is set correctly, as it can affect assembly loading.

Use Fusion Log Viewer: Use the Fusion Log Viewer tool to find more details on the assembly loading failure.
