Getting "GenerateDepsFile" task failed unexpectedly with KeyNotFoundException when publishing project

I am getting "GenerateDepsFile" task failed unexpectedly with KeyNotFoundException when publishing my projects.

Below are the conditions that trigger the issue:

.NET Core 3.0 Preview 4
WindowsAzure.Storage 9.3.3 is in a .NET Standard library

This can be fixed by either going back to Preview 3 or add WindowsAzure.Storage directly into the .NET Core project.

Error in build log:

Can anyone help with where to put <DepsFileGenerationMode>old</DepsFileGenerationMode> ? I tried in my csproj file and it doesn’t work.

I’m not sure if this has been fixed for preview 5 or not. I will take a look. However, you can work around the issue by setting the following MSBuild property:

<DepsFileGenerationMode>old</DepsFileGenerationMode>
