I have two separate solutions with custom Nintex Workflow Actions. When I deploy one, the other retracts. The same does not happen when I deploy one of my actions and the SDK sample action. I can have them both out there at the same time. The assembly names are different but the keys are the same, however, I have tried with a different key for one without success. Any ideas where I'm getting the conflict with my two solutions? Note: deploying from separate instances of VS on my SharePoint dev server.
