Microsoft naming is incomprehensible sometimes. Doing a .net framework -> dotnet core transition at the moment has really exposed me to a lot of this.
"Let's deliberately choose a name for a thing that could be confused for a different thing. [some amount of time and nefarious activity later, and with false innocence] Oh, we've always called it that, so you can't have that namespace even though you think it should belong to that technology that predates our suspicious name with which we encroached on non-Microsoft technology."
