I get the same three errors on a file...new .NET MAUI App template project using .NET 8.0 in VS 2022 17.8.2.

All I did after creating the project was switch my debugging target to my Android local (emulator) device and right-click Rebuild on the solution, which only has the new project in it.

Here is the binlog file created from my Developer Powershell terminal in VS 2022 using command dotnet build MauiApp1.csproj /bl:msbuild.binlog:

same here, just wanted to get into MAUI and thats what you get greeted with when trying the basic boilerplate of a new project

This fixed it for me: #18904 (comment)

I've been getting these same three errors on a sporadic basis for the past several weeks. I can't tie it specifically to a MAUI or Visual Studio version. When I see these errors, I do a clean, exit, and restart VS. That will clear up this issue for a while. I also get errors about these files being "open by another process" way too often... This is very disruptive.

Same issue for me. I just changed .net 7 to .net 8 in csproj and this error comes.

I have attached .binlog see #18636 (comment)

This just continues to happen several times. Still no workaround??

Same problem in .net 8 MAUI Application.

I just created a new MAUI app using .net8.0 and I had this issue.

It helped me to edit .csproj file and remove everything targeting ios, maccatalyst and tizen. Don't know which one caused the issue. But it was writing about missing files for Android (like AndroidManifest.xml directly in project folder) - so definitely unrelated things.

Oh I also got this issue when targeting Windows:
The project needs to be deployed before we can debug. Please enable Deploy in the Configuration Manager.

It was enabled. Removing those targets also helped this problem.

We think that this might be solved by #21838. Please try the nightly feed or wait for a next release where this change is included. If this turns out not to be the case, please feel free to open a new issue about this and refer to this one, thanks!
