Microsoft.NET.Sdk\Sdk\Sdk.NuGet.targets is not found

[FixRM]

Hello, local bulid is ok, but I can't build project in Azure Pipelines:

Error MSB4019: The imported project "C:\hostedtoolcache\windows\dotnet\sdk\3.0.103\Sdks\Microsoft.NET.Sdk\Sdk\Sdk.NuGet.targets" was not found. Confirm that the expression in the Import declaration "C:\hostedtoolcache\windows\dotnet\sdk\3.0.103\Sdks\Microsoft.NET.Sdk\Sdk\Sdk.NuGet.targets" is correct, and that the file exists on disk.

The repo here uses an old SDK and TFM. It's likely that it needs to be updated to target .NET Core 3.1 or .NET 5. The Pipelines install steps reference 3.0.x, which is out of support. Updating this to 5.x should help: https://github.com/microsoft/devops-for-windows-apps/blob/master/azure-pipelines.yml#L61

I see, thank you. I already tried to update but it doesn't work as well.

p.s. I also changed dotnet version in "install dotnet" task
