Sometimes when using ILMerge, the strong name is not valid when the dll is created. It would be a nice feature to validate the strong name first before uploading. And if the strong name is not valid, automatically resign the dll to fix the issue.

1.) Run sn -vf *.dll
2.) Confirm that the dll is either a delay or test signed
3.) Run sn -R *.dll *.snk
4.) Confirm that the dll is now valid
