SYMPTOMS
When you start a Microsoft .NET Framework 2.0 managed application that has a Microsoft Authenticode signature, the .NET Framework 2.0 managed application takes longer than usual to start.



CAUSE
This problem occurs because a .NET Framework 2.0 managed assembly that has an Authenticode signature takes longer than usual to load. The signature is always verified when the .NET Framework 2.0 managed assembly that has an Authenticode signature is loaded.

Additionally, the .NET Framework 2.0 managed assembly may take longer than usual to load because of various other settings. For example, the .NET Framework 2.0 managed assembly may take longer than usual to load because of the network configuration.

MORE INFORMATION
This hotfix adds the generatePublisherEvidence configuration setting to the .NET Framework 2.0. After you apply this hotfix, you can use this configuration setting to disable signature verification in a .NET Framework 2.0 managed application. You can use this configuration setting in an application configuration file. To do this, add the following code to the .exe.config file for the .NET Framework 2.0 managed application.  When you disable signature verification, the .NET Framework 2.0 managed application starts faster.

Note When you disable signature verification, the .NET Framework 2.0 managed application no longer receives publisher evidence. This behavior affects the .NET Framework 2.0 managed application only when you use publisher evidence or when you use the PublisherIdentityPermission class.

The generatePublisherEvidence configuration setting will be available in the version of the .NET Framework that follows the Microsoft .NET Framework 3.0.

To create an application configuration file that contains this configuration setting, follow these steps:  Create a file, and then name the file the .exe.config file. In a text editor, open the file that you created in step 1.  Add the following code to the file.    Save the changes to the file.</li></ol>
