When I try to build a MUAI project, it gives the error “The project doesn't know how to run the profile sample.WinUI". The project gets built but it doesn't run. I am using Visual Studio 2022 Preview(17.0.0 Preview 1.0) and .NET version 6.0.100-preview.5.21302.13

This is still an issue for me with VS 2022 preview 3 and .NET 6 preview 6. Note that in VS 2021 the solution was to right click the WinUI project and "Deploy" but this option is not present in 2022.Ant– Ant2021-07-15 11:33:44 +00:00Commented Jul 15, 2021 at 11:33

This may related to the "Development tools for .NET" component of the Visual Studio installation.

Haven't found this documented yet, but it turns out you need to install the 2022 equivalent of Single-project MSIX Packaging Tools for VS 2019. You can find the 2022 version here:
Single-project MSIX Packaging Tools for VS 2022
Once installed you can build the WinUI project then right-click and select Deploy. Debugging and running should then work as expected.

I tried your suggestion but it didn't work for me. I'm trying to debug a windows console application and I'm getting the same exact error message as the op

@DarthVegan this answer is specific to preview releases of .Net 6 MAUI projects. Seeing this error in other contexts would suggest you don't have the right project selected as the startup project.
