Hi all, I have a bizarre issue regarding plugin Assembly compilation. I have raised a case with Microsoft but I thought I'd ask here also in case anybody else has experienced this issue.
I have a plugin assembly which I have developed in VS 2012 Professional. The assembly has no issues and all plugins run correctly.
I now wish to upgrade to VS 2015 Community edition, however when I compile *exactly* the same project with *no* changes whatsoever, and upload it to CRM Online, I get the error "System.MissingMethodException: Method not found: '!!0[] System.Array.Empty()'" whenever a plugin runs.
I have tried removing the old assembly - completely unregistering it - and re-registering the new assembly - but no joy. I can overwrite the assembly generated with VS 2015 with the assembly generated by VS 2012 as a simple update, and everything works fine. Updating to the VS 2015 assembly and everything errors out.
This seems pretty crazy! Has anybody here experienced anything similar?
AHA, Ben
