Describe the bug

Visual Studio for Mac updated and also .NET SDK and runtime were also updated. Unfortunately, we are not able to build our project anymore (Android & iOS). We are encountering error in one of our project in the solution that is a.NET Portable (PCL 4.5 - Profile 259).

Error MSB4019: The imported project "/usr/local/share/dotnet/sdk/7.0.304/Microsoft/Portable/v4.5/Microsoft.Portable.CSharp.targets" was not found. Confirm that the expression in the Import declaration "/usr/local/share/dotnet/sdk/7.0.304/Microsoft/Portable/v4.5/Microsoft.Portable.CSharp.targets" is correct, and that the file exists on disk

To Reproduce

Use Visual Studio 2022 for Mac latest version

Exceptions (if any)

I had the same problem on Visual Studio for Mac 17.6 (build 1575).

I did not update any nuget packages or project configuration, only the IDE. I guess this messed up my build. It showed the same error as in the topic starter:

Error MSB4019: The imported project "/usr/local/share/dotnet/sdk/7.0.304/Microsoft/Portable/v4.5/Microsoft.Portable.CSharp.targets" was not found. Confirm that the expression in the Import declaration "/usr/local/share/dotnet/sdk/7.0.304/Microsoft/Portable/v4.5/Microsoft.Portable.CSharp.targets" is correct, and that the file exists on disk

When I tried msbuild from a console, it showed a different error. Same error was displayed when I tried JetBrains Rider:

error XA1032: Failed to resolve 'System.Net.Http.HttpClientHandler' from 'Mono.Android'. Please check your `AndroidHttpClientHandlerType` setting.

Then I followed this advice on stackoverflow, and it helped me to fix the build for JetBrains Rider. It still does not work for MS VS with the same error as in the topic starter.

P.S. JetBrains rules in the world of IDEs. Microsoft should just buy JetBrains, as it bought Github years ago. 😄 I can only image what "coding beasts" work at JetBrains. 😎

I tried the fix you mentioned but I am still encountering the issue.

Yes, as I said, that fix did not address the issue for MS VS. It only worked for JetBrains Rider.

I've managed to fix the issue. What worked for me was to set my "core" project to build with MSBuild at Mono.

You can find this in the project Properties->Build->General, there is a checkbox for "Build with MSBuild on Mono", Make sure it is checked.

Hopefully, this will help others too.

Note: I'm working on Xamarin Android and Xamarin iOS, not Xamarin Forms.

I had the same issue, and actually setting "Build with MSBuild on Mono" on the Xamarin Forms project fixed it. In my Solution, this option was set on the Xamarin Android and Xamarin iOS projects, but not on the Xamarin Forms one.
