Compilation error with basic project

Question

I just started to use 200.8

I have VS 17.8

Started a project with the template and just compile it (no changes)

I get the error:

Severity Code Description Project File Line Suppression State
Error MC1000 Unknown build error, 'Could not find type 'WinRT.WinRTRuntimeClassNameAttribute' in assembly 'C:\Users\mody\.nuget\packages\microsoft.windows.sdk.net.ref\10.0.19041.31\lib
et6.0\WinRT.Runtime.dll'. Line 14 Position 23.' WpfMapApp1 C:\Projects\WpfMapApp1\WpfMapApp1\MainWindow.xaml 14

As far as I understand I have everything installed.

Any idea?

Thanks for pointing out this error in our doc. The correct minimum is 17.12. I'll make sure that gets fixed.

Hi

Upgrade to VS2022 17.14 solved the problem.

The docs say 17.8 is supported (that is what I had before upgrade).

Many thanks

After creating project, you can find .NET version in project properties:

You can select .NET version in next step after choosing project template, selecting location for project:

Another one thing is Visual Studio version. I have found: Visual Studio 2022 v17.12 with .NET 9
