Exception on client

I can't get the source to run after compiling.

System.TypeLoadException was unhandled

/* this is where the exception occurs */


Any ideas ?

> any ideas?

yes ... 

maybe another version of RDPAddins.Common is in GAC

try gacutil /l RDPAddins.Common

if there is any entry(of RDPAddins.Commeon) in GAC

1. try uninstall binary version

2. run gacutil /u RDPAddins.Common


new version no longer need to be installed in GAC nor strong name.

Yes it was in the GAC. Now it works. I don't know why I didn't think of that! Thank you very much for your help.

Happy Holidays
