When you're using a delay-signed strongly-named assembly in ASP.NET you might get this error:

Configuration Error  

Description: An error occurred during the processing of a configuration file required to service this request. Please review the specific error details below and modify your configuration file appropriately.
Parser Error Message: The check of the signature failed for assembly 'MyAssembly'.
Source Error:

Line 229:        <add assembly="System.EnterpriseServices, Version=1.0.5000.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" />

Line 232:      </assemblies>

Even if you've set up verification skipping with sn.exe -Vr, you'll need to restart the ASP.NET worker process before it takes effect as the information is only read when the process is first started.

I had an issue that I struggled with in relation to delay signing. I shared this problem in newsgroup. I thought it would be beneficial to share this with the readers here as well. [Symptom] Although I tried to get a string from a resource file for a different culture, it always returned a string for English (default). [Cause] Satellite assembly was partially signed along with the main one. Main assembly was registered on the machine to be ignored (sn -Vr MyLibrary.dll), but satellite assembly wasn't. ResourceManager did not throw any exception, and it silently defaulted to the resource for English which is embedded in the main assembly. [Resolution] Either sign the satellite assembly with the private key or do "sn -Vr MyLibrary.dll". Original post:

thats because SNed assemblies are loaded domain neutral IIRC
