As you might have noticed there is a new version of the plugin registration tool out with the new version of the SDK 6.1 released in may 2014. It has gotten a nice facelift in the UI and can now be found in the Tools directory.

However, I have had some issues when working with my on-premise org (it worked fine with online). I got the following error when trying to register a step on a plugin assembly.

Unhandled Exception: System.ServiceModel.FaultException`1[[Microsoft.Xrm.Sdk.OrganizationServiceFault, Microsoft.Xrm.Sdk, Version=, Culture=neutral, PublicKeyToken=31bf3856ad364e35]]: Assembly file name (CRMKonsulterna.Modelon.Plugins.dll) is in invalid format. Only file name is allowed.

I’m including it all here for searchability. I have highlighted the message that is the interesting part.

When retrying it in the older version of Plugin Registration tool, it works just fine, as long as I re-register the assemblyfile. If I keep the assembly file and try to register the step in the older version (6.0.0001.0061) I will still get the error, so I did have to unregister the entire assembly and register it all over. This also only seems to show up when registering to disk (I havn’t tried registereing to GAC as I seldom use that).

Also do note that despite right clicking on the assembly-plugin and pressing “Add step” it seems to omit this information in the form for registering the step so make sure that your step is registered on the correct assembly. I got a bit confused and registered quite a few on ActivityFeeds until I noticed this.

For reference, this is for Plugin Registration Tool version and I am testing it on CRM 2013 UR2 Onpremise.

I am also quite sure these bugs will be fixed soon by Microsoft, but it might be a good idea to keep a copy of the older Plugin registration tool just in case.
