Unable to open class diagram in designer
Unable to open CustomerClasses.cd in designer
Learning C#, WPF and Visual Studio, in a demo project I have these 2 class diagram files:
- CustomerClasses.cd - opens in code view only
- ViewModelClasses.cd - opens in designer view only
Note: files available from here https://github.com/puckchaser/MvvmDemoApp/tree/master/DemoApp/Class%20Diagrams
First challenge was installing the designer feature, see here: Class Diagrams in VS 2017
The right click context menus for both files (via solution explorer) are different. From reading around I gather that a probable reason that CustomerClasses does NOT open in designer view is due to malformed XML, but neither I nor (as far as I can tell) Visual Studio is able to find any issue.
Image shows CustomerClasses.cd (left) displayed as code and ViewModelClasses.cd (right) displayed as diagram. Menu for CustomerClasses.cd (far right) does not work.
But it is shown in the related article...
I believe that I should be able to see the design view because it is shown in the related article as figure 11: https://msdn.microsoft.com/en-us/magazine/dd419663.aspx?f=255&MSPPError=-2147217396
Furthermore, the xml of the file seems to correspond to what is shown in the diagram... this is driving me nuts
FWIW - this is one of the best walk-throughs I've come across for learning WPF in C#.
Fixed but not sure why
I downloaded the source files from github (which happens to be a different source than originally used) https://github.com/puckchaser/MvvmDemoApp and tried again, this time it works.
I used version control to try and identify the root cause of the issue but I don't see anything that explains this to me. There were changes in the file: DemoApp.csproj but I don't know if they could explain this :-/
