  • in C:\Program Files\Microsoft Visual Studio\2022\Professional\Common7\IDE\Extensions\Microsoft\Entity Framework Tools\Templates\Includes\EF6. Utility.CS.ttinclude `private DynamicTextTransformation(object instance) { _instance = instance; Type type = _instance.GetType(); _write = type.GetMethod("Write", new Type[] { typeof(string) }); _writeLine = type.GetMethod("WriteLine", new Type[] { typeof(string) }); _generationEnvironment = type.GetProperty("GenerationEnvironment"); _host = type.GetProperty("Host"); _errors = type.GetProperty("Errors"); }` – Jahanzaib Khan May 29 '23 at 10:10
  • This issue is utterly odd, and recent. It should be reopened. Redirecting to and old question with a myriad of answers is of little use. – carloswm85 May 31 '23 at 17:18
  • This is the solution that worked for me: https://gist.github.com/carloswm85/461df6ad36c96e69a9dab0d88f599d39 – carloswm85 May 31 '23 at 17:50

  • The workaround described in this link worked for me: https://developercommunity.visualstudio.com/t/Entity-Framework-Running-Transformation/10371307 – napsebefya Jun 02 '23 at 11:45
