Point of Sale will not even Compile... #457

Is this with Visual Studio on Windows? Just tried it on macOS with VS Code and compiled and ran just fine here! |
Yes, Visual Studio 2022 [17.9.5] .. My first indication was the warning This would (to me) indicate that the project files had not been updated....so I figured I would ask... |
|
Yeah I think there is a PR for that but that didn't get merged yet. Regardless, it works fine for me without it, as it should. The real error seems to be this one: |
|
Yes, as I said it was an indicator... as to the can not resolve type... that may be to be related to:
But not sure.... Also, note that this was done on a relatively clean machine that had not done any MAUI work previously. When opening the SLN in VS-2022 is indicated some additional components needed to be installed, and I let the VS ecosystem take care of that. If you are using Vs-Code (this is 40% hypothesis, not use-case I actually do) that spawns off a bunch of dotnet command lines and there may be "workloads" involved that do not get set in the expected manner when the normal use case is via Visual Studio..... |
I realize this is not a "Complete Application", but I would expect it to at least compile [hopefully, I am doing something wrong]
