I received an error opening a CRM project in visual studio: “Unknown project type GUID 4C25E9B5-9FA6-436c-8E19-B395D2A65FAF.” That GUID is related to a MS CRM developer toolkit. It’s not supported on MS CRM 2013, MS CRM 2015 or MS CRM 2016, so what do you do? The solution is quite easy: Make a backup of the offending .csproj file and then open your .csproj file that contains that GUID and simply remove that GUID.
The project should open with no complaints and build just fine.
