Visual Studio 2015 HTML Editor not working after update RRS feed

  • Question

  • Hi,I hope I use all English MS terminology correctly, but I'm working on a German development Environment and this forum doesn't seem to be offered in German too (at least I'm directed to here when I try to look for help on the German MS Support page) , therefore I have to translate.

    Here at work I'm using VS 2015. Developing a Web application worked fine until I had to open the solution "Client Tools" for that Web application. Opening this Project required an update of VS, which then required me to "repair" the VS Installation from System Control Panel "Apps and Features".Opening the Web application again, VS told me that it could not load the Web Project any more as it was "incompatible". It took me about two days researching to find that I had to remove the ProjectTypeGUID {E3E379DF-F4C6-4180-9B81-6769533ABE47}, now I can at least load the project again, but opening the cshtml files fails with a "The operation could not be completed. Invalid pointer" message. If I use Open With.. and select "Source Code (Text) Editor" or "HTML (Web Forms) Editor" works, so I think I'll be able to reconfigure VS to use the WebForms Editor for cshtml, but I neither know if that is appropiate for the Project nor if that causes other Problems (e.g. with IntelliSense).

    For this Problem Google directed me to a few sites all stating the same (use devenc /resetuserdata from a VS developer console, clear the ComponentModelCache in the user Profile, reinstall the updates), but the first two didn't help and it seems that I can't find the updates for VS 2015 as the only things MS offers are Updates for VS 2017 or TeamExplorer 2015. Trying to select an "old Version" download forced me to Register but then also only directed me to the download for VS 2017 Community Version. I found the DotNetCore.1.0.0-VS2015Tools.Preview2.exe download mentioned in another article, but this says that prererquisites are not fulfilled and I have to install Update 3 before trying again.

    Other issues I found in MS archives were closed as "unreproducable" as the askers weren't able to provide log files or dumps MS asked for (I don't even know where to find such a dump), although I think that if that problem occurs as often as the number of questions suggests, there must be a way to reproduce it within the MS labs. But I think I digress. Back to the topic..

    What would you propose? Is there a definite way to make the HTML Editor work again? Should I use the HTML Editor for WebForms or the Text Editor offered by VS?
