What you expected to see, versus what you actually saw

If workload restore was required, run something like dotnet workload restore to verify dependencies in a build-enabled state.
Or, parse csproj without build and verify dependencies.

For example, a similar product that verifies dependencies without build is dotnet-outdated.

This is an important piece of support for .NET. Interestingly, this change #9385 was made to enhance that support.

Looking further into this, I'm getting messages like this one, same as the original poster:

/usr/local/dotnet/current/sdk/8.0.303/Sdks/Microsoft.NET.Sdk/targets/Microsoft.NET.Sdk.ImportWorkloads.targets(38,5): error NETSDK1147: To build this project, the following workloads must be installed: wasi-experimental [/tmp/package-dependency-resolution_QwqwLB/Project.csproj]
/usr/local/dotnet/current/sdk/8.0.303/Sdks/Microsoft.NET.Sdk/targets/Microsoft.NET.Sdk.ImportWorkloads.targets(38,5): error NETSDK1147: To install these workloads, run the following command: dotnet workload restore [/tmp/package-dependency-resolution_QwqwLB/Project.csproj]

And looking at the .NET source, it may be interesting to set the DesignTimeBuild property to avoid this error since the build is only interested in getting the packages dependency graph.

It would probably need to be set in that group:

dependabot-core/nuget/helpers/lib/NuGetUpdater/NuGetUpdater.Core/Utilities/MSBuildHelper.cs

Lines 710 to 715 in 10e5c7c

	<PropertyGroup>
	<TargetFramework>{targetFramework}</TargetFramework>
	<GenerateDependencyFile>true</GenerateDependencyFile>
	<RunAnalyzers>false</RunAnalyzers>
	<NuGetInteractive>false</NuGetInteractive>
	</PropertyGroup>
