Doing continuous integration builds using a hosted agent in Azure DevOps, I now have builds failing with error NETSDK1005. Microsoft documentation notes this as a known issue that occurs when using preview versions of .NET 5 and Visual Studio 16.8, but I assume hosted agents should be using stable versions.
This is the error message from the logs (repeated for several projects):
[error]C:\Program Files\dotnet\sdk\5.0.100\Sdks\Microsoft.NET.Sdk\targets\Microsoft.PackageDependencyResolution.targets(241,5): Error NETSDK1005: Assets file 'D:\a\1\s\PROJECTNAMEHERE\obj\project.assets.json' doesn't have a target for 'netstandard2.0'. Ensure that restore has run and that you have included 'netstandard2.0' in the TargetFrameworks for your project.

When I build the same codebase in the same configuration on my personal machine with Visual Studio 16.7.7 and .NET Framework 4.8.0.03761 the build succeeds.

Hello @Joe Manke , thank you for taking time to post this issue in Microsoft Q&A forum. It seems this issue is related to Azure DevOps and .NET, as you know, our forum(Microsoft Q&A vs-msbuild) is about the usage of MSBuild, build customization and MSBuild extensibility via tasks, loggers and hosting, so I will help to move the vs-msbuild tag.
Besides, as DSPatrick suggested, you can post questions about Azure DevOps in Developer Community azure devops and StackOverflow tagged with azure-devops, and you can get more professional help there. Have a nice day:)
Workaround: Add the UseDotNet step to use .NET Core 3.1 instead of .NET 5.0.
