    Hello All,

    In my case it's not using any third party dll.

    although a separate library project is there in the same one solution.

    I cannot build my class library project as it is throwing a compile time error as

    Cannot import the following key file: <filename>.pfx. The key file may be password protected. To correct this, try to import the certificate again or manually install the certificate to the Strong Name CSP with the following key container name: VS_KEY_ E2AEBF22AB52DD08.

    so does that affecting my plugin not to execute.

    I guess these issue may related to the key you use to sign your plugin, did you use a old key or you create a new key for your plugin?

    You can check below link which seems has the same issue with you。

    Hi,

    Is this Team Project? Because if some one registered Plugin with new class file and then if you try to register this Plugin and in your solution you dont have respected class file then it will throw above error. If it is team project then pull latest code and build it then update your assembly.

    Hope it helps you

    Thanks.

    Actually my system is being used by another user previously.

    2. These keys are password protected so how to resolve them.

    Hello Alagu,

    i have resolved the issue from visual studio compilation.

    and redeploy the plugin.

    But still same issue

    Unhandled Exception: System.InvalidOperationException: The plug-in type "sample plugin class" does not exist in the specified assembly.

    But in my plugin there is one class library project within one solution that i am directly using within this plugin.

    That class library project has some post build events associated with it.

    which is on building the solution do some work.

    I doub't on this if it could be the problem.

    Hi
    So in your plugin, you have two project is (1st)one is class library and (2nd)another one is main project. If it is correct then problem seems like you only register the 2nd dll in CRM using plugin registration tool. You havent register the 1st dll still yet.

    If my above statement is true then do the follow below
    CRM onpremise
    1st dll put in to GAC on CRM application server.

    CRM on line

    Merge the 1st and 2nd dll using merge tool and register in CRM using plugin registration tool
