SDK: Upgrade of .net Framework from 4.5.2 to 4.6 breaks custom plugins and workflows

(0) ShareShare

Posted on by Felix Brem 55

we try to upgrade the .net framework version of our custom plugin and workflow projects. unfortunately this breaks all registered plugins and workflows.

We are using CRM Online, all assemblies are in sandbox mode.

System.MissingMethodException: Method not found

Does anyone know, how to avoid to re register all Plugins, Steps and Workflows?

Thank you in advance

    We are currently trying to re-compile our plugins against .net 4.6.

    The exception we get sounds like the same as above:

    System.MissingMethodException: Method not found: '!!0[] System.Array.Empty()'.

    This occurs when a call to ITracingService.Trace and only a string is passed in without any params to substitute in. (params object[] args)

    This is ok at 4.5.2.

    This is ok on prem when the plugin is compiled targeting 4.6

    This fails on line when the plugin is compiled targeting 4.6.

    Is this the exception you were experiencing ?

    Was the only solution to re-register the plug-ins because the symptoms are as if CRM online is running 4.5.2.

    Hello Caffreybcc,

    Is this the exception you were experiencing ?

    It sounds like, but i have to verify it. If so, thank you very much for some kind of solution, because in this case we can probably pass a dummy parameter to the tracing calls. How did you figure out, that this is related to the tracing service? I

    This was a assumption i made, but i did not test it out, because i did not want to break our environment. Also, i have been in vacation the last 2 weeks, so this problem was on idle.

    . 

    not a very helpful response, sorry for that :-/

    It seems, that online only .net version 4.5.2 is supported. I did not found a solution to this.

    When you build the plugin in VS2013 with .NET 4.6.1 the trace can be written as

    tracingService.Trace("TraceMessage");

    However if you build with VS2017 with .NET 4.6.1 this throws the Method not found: '!!0[] System.Array.Empty()'. error

    You can fix this by either downgrading to .NET 4.5.2 of writing the trace like this

    tracingService.Trace("{0}", "TraceMessage");
