tag does not exist in XML namespace

Question

This error seems to be posted all over the place but each one seems to have its own solution, none of which solved my problem.

I am getting an error for a Resource D

Answer 1

Looks like it was mostly a user error. But this could happen to others. When I copied the xmlns:moduleviewmodel definition from its original file I had to add the assembly= portion on my own. Like I said I both did it myself as well as use the autocomplete the follows from typing 'xmlns:moduleviewmodel=' . Right before we found the error we tried the autocomplete again because we found that there was one of the 7 namespaces not generating the error. It was then that I noticed that there was a letter in assembly path that was not capitalized that should be. The weird thing is the autocomplete actually inserts this error on its own. While we were compiling that I noticed the erroneous letter. The weirder thing is that after I fixed all the paths manually we tried the autocomplete again and it spelled it correctly.

I have no idea the cause of the errored autocomplete but with the fixed letter it compiles just fine.

Now I just wonder if anyone will believe the autocomplete was changing up on me!
