How Can I Enable Fusion Logging to Troubleshoot .NET Assembly Binding Failures?

Troubleshooting .NET Assembly Binding Issues with Fusion Logging

Resolving assembly binding problems in .NET applications can be difficult. The .NET Framework's Fusion component manages assembly binding, and enabling its logging is vital for diagnosing failures.

Enabling Fusion Logging:

Follow these steps to activate Fusion logging:

1. Access the following registry key:

   <code>HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Fusion</code>

2. Create or adjust these DWORD values:

   • ForceLog: Set to 1
   • LogFailures: Set to 1
   • LogResourceBinds: Set to 1
   • EnableLog: Set to 1

3. Create a string value called LogPath and set its data to your desired log directory (e.g., C:\FusionLog\). Remember the trailing backslash and ensure the directory exists.

4. Restart your application to apply the registry changes.

Fusion will now log all assembly binding failures to the specified location. These logs provide crucial information for identifying and fixing the root cause of the failures.

Important: Disable Fusion logging after troubleshooting to avoid excessive log file generation and potential performance impacts.
