System.Resources.Extensions.Tests resource re-generation is broken after BinaryFormatter extrication

[stephentoub]

Trying these instructions:

runtime/src/libraries/System.Resources.Extensions/tests/System.Resources.Extensions.Tests.csproj

Lines 34 to 55 in fcdb6db

	<!-- Use the following target to regenerate the test resources file.
	This is done from a test application and checked in so that we don't run
	product code during the build.
	Important:
	When invoking this target, pass the target framework in as well, substituting
	the X with the current major version:
	dotnet build -f netX.0-windows && cd outputdir && dotnet build -f netX.0-windows /t:GenerateTestResourcesFile. -->
	<Target Name="GenerateTestResourcesFile">
	<PropertyGroup>
	<_executor>Microsoft.DotNet.RemoteExecutor.dll</_executor>
	</PropertyGroup>
	<ItemGroup>
	<ExecuteMethod Class="System.Resources.Extensions.Tests.TestData" Include="WriteResources" Parameters="$(MSBuildProjectDirectory)\TestData.resources" />
	<ExecuteMethod>
	<ExceptionFile>$(TargetDir)%(Class)%(Identity).exception.txt</ExceptionFile>
	</ExecuteMethod>
	<ExecuteMethod>
	<Command>$(NetCoreAppCurrentTestHostPath)dotnet exec --runtimeconfig $(TargetDir)$(TargetName).runtimeconfig.json $(_executor) $(AssemblyName) %(Class) %(Identity) %(ExceptionFile) %(Parameters)</Command>
	</ExecuteMethod>
	</ItemGroup>
	<Exec Command="%(ExecuteMethod.Command)" WorkingDirectory="$(TargetDir)" />
	</Target>

Results in:

cc: @bartonjs, @adamsitnik, am I just holding it wrong or do the instructions need to be redone?

That looks like some piece is missing the package reference to the new nuget package, since it's complaining it can't find the 9.0.0 version of the assembly.
