How to exclude a project from dotnet test run

Question

I have two projects: UnitTests.csproj (xunit) and IntegrationTests.csproj (specflow)

I'm using
dotnet test MySolution.sln --filter FullyQualifiedName\!~IntegrationTests
to run unit tests.

However, my IntegrationTests.csproj project contains a method decorated with [AfterTestRun] attribute, and it appears that my command runs that method, understandably, even though no tests were run from IntegrationTests.csproj project.

I have tried putting [Category("Integration")] on the [AfterTestRun]-decorated method, but that doesn't seem to be helping.

Question: How can I filter test lifecycle methods with dotnet test and xunit?

My workaround is to add the following code to all integration test lifecycle methods:

if (Environment.GetEnvironmentVariable("TEST_SERVER_URL") is null) return;
