An unhandled exception of type 'System.TypeInitializationException' occurred in System.ServiceModel.dll. Additional information: The type initializer for 'System.ServiceModel.Diagnostics.TraceUtility' threw an exception.

 Common Causes:

• Configuration Errors: Issues in your WCF configuration (e.g., app.config or web.config) could trigger this exception. Check that your configuration files are correctly set up, especially sections related to diagnostics and tracing.

• Missing or Corrupt DLLs: If a required DLL (e.g., System.ServiceModel.dll) is missing or corrupt, the type initializer might fail. Ensure that all necessary assemblies are present and correctly referenced in your project.

• Permissions Issues: The TraceUtility class may attempt to access system resources, such as event logs or trace files. If the application lacks the necessary permissions, it could cause this exception. Ensure your application has the appropriate permissions to access these resources.
