Hello Guys,

I have an existing assembly which I want to update. This assembly contains 4 workflows registered as plugins. This is already present in the environment and I want to update it. But I am being thrown the following error. I am trying to register it with Isolation mode mentioned as "None". Please help guys. 

Using On Premise MS Dynamics CRM 2016.

    RE: Plug-in assembly does not contain the required types or assembly content cannot be updated. error

    I had the same problem on 9.0 on premise, and because I am actually creating PluginTypes based on the actually DLL uploaded, by first unregistre all plugins no longer in the plugin assm, then upload the DLL, and finally registre plugintypes, based on class decoration properties in my assembly plugin classes, i know for sure that the plugin's are not missing. In the early days of 9.0 online, I experience that a lot a customizations was cached - even long after a deployment of a solution, and publish of same.... So i was thinking, maeby the 9.0 on premise i caching the DLL, and is comparing with the old DLL, even after a new DLL has been uploaded when registre new steps. To see if this was the case, i did the following:  1) try to deploy.  argh..  got the error.  2) iisreset (only possible onprem..). 3) try to deploy again ... voila, now it worked.

    You can Un-Register the specified  plugin through plugin registration tool and try to do again...

    Hope it will help!!!

    RE: Plug-in assembly does not contain the required types or assembly content cannot be updated. error

    Hello

    I removed the plugin from my CRM instance but still I am getting the same error. The problem is that I cannot find the plugin in steps and plugin assembly section of CRM and at the same time I cannot register the assembly because of the above error.

    Any suggestions?

    Had a very weird case, and the tool did not add value.

    More specifically, I changed the minor number of the version number of the assembly (Major.Minor.Build.Revision), and because of the mismatch it would not allow me to update the assembly. Finally found the mismatch and also documentation that the Major and Minor parts of the version number should not change.

    Hope this helps at least someone.

    You can always use ILMerge instead of links

    Hi

    I am not going to correct anything, but to share my experience.

    I have a DLL solution for my plugin and two external DLL solutions (Helper classes and another static dll which helps me translate error code into easy to understand error messaage for the users)

    So, i make my reference in my plugin project with those two projects (all within the same solution) and when i push it, i received this error.

    Thanks to Shahar Journo, a coworker of mine, i learn that i can not do that :(

    That instead of using an external reference, i have to Add as a link all the files of those two other projects to create a unique DLL with the three files i need.

    Now, when i build my solution, i have a unique DLL with all my needed classes and i am able to push it with the Plugin Registration Tool.

    Hello Alex,

    Thanks for your suggestion. It was a weird issue. I was the deployment admin, I registered the plugin in "None" isolation mode and the issue was CRM , for some reason was thinking that am trying to register in Sandbox isolation mode. This was causing the issue. I was being thrown the No sandbox server available error. I registered the plugin again and it seems to work now.

    Hi Donald,

     you have to look at the differences between the assembly you have in CRM and the assembly you are trying to register. Your new assembly has to have the same signature (you did not compile it with a new key, right?), and it has to have the same classes which are currently registered as plugin steps. You can add new classes, but you can't remove/rename existing classes (unless you remove a step as well).

    Hi Ravi,

    Thank you for your suggestion. Will definitely check this tool out.  As mentioned earlier, there is no input/output parameters when it comes to this assembly. This is because, this assembly contains 5 items and all 5 of them are workflow as plugin activities. Any suggestions?
