During the process of upgrading from 4.0 to 2011 I have run into a problem. There is a custom workflow assembly that aprently needs 'Microsoft.Crm.Sdk, Version=4.0.0.0' but the target server has 'Microsoft.Crm.Sdk, Version=5.0.0.0'. I dont have the code
to recode the plugin.
Any suggestions to what I can try?
