Running dotnet ef migration for class library gives error MSB4006

Question

I have an ASP.NET Core Web Application (.NET Framework) project focused on the .NET Framework 4.6.2.

I injected the Entity Framework into a web project and set up and run

dotnet ef migrations add Initial

from the catalog of web projects. Migration created, all is well.

I want to reorganize the code so that my entities and the db context are in the class library instead. So I created a separate class library project (.NET Framework), also targeting the .NET Framework 4.6.2.

From the web project directory, I run

dotnet ef migrations add Initial --startup-project . --project ..\MigrationTest.Entities

where MigrationTest.Entitiesis my class library.

This time I get:

C:\Projects\Experiments\MigrationTestNoIdentity\MigrationTest.Entities\obj\MigrationTest.Entities.csproj.EntityFrameworkCore.targets(4,5): MSB4006: , "GetEFProjectMetadata". [C:\\\MigrationTestNoIdentity\MigrationTest.Entities\MigrationTest.Entities.csproj] . .NET Core MSBuild. BaseIntermediateOutputPath MSBuildProjectExtensionsPath, -msbuildprojectextensionspath.
