I got the error whilst trying to deploy a plugin using the CRM development toolkit
Error 1 Error registering plugins and/or workflows. Supported deployment does not agree with message availability C:\Program Files (x86)\MSBuild\Microsoft\CRM\Microsoft.CrmDeveloperTools.CrmClient.targets 176 4 CrmPackage
This was an odd error and I couldn’t work out what was causing it. if you try and search for errors about the CRM development kit you get a lot of errors and information but not a whole lot of solutions going on.
The best bet would be to check Danial Cai’s blog
Although I didn’t find the solution to my problem here I did learn quite a bit about the CRM developer toolkit.
I finally worked out that I had set the plugin to work offline as well as online but I had not changed the Entity to work off line.
To fix the problem I went to my solution, went to the entity and ticked the checkbox
offline Capability for CRM for Outlook
Then it deployed successfully.
