The main issue here makes it different from other available problems and solutions (here) is that, I am working with a previously working M# project and right now after upgrading to M# v4.8.334 (or maybe some other modifications regarding Visual Studio 2017 installation), if I want to add any new fields to any entity in MSharp IDE, it gives the following error
Base issue: The partner transaction manager has disabled its support for remote/network transactions. (Exception from HRESULT: 0x8004D025)
One important point to note is that for newly created projects it is working correctly without this exception so my DTC settings and service are configured correctly.
