GitLab Runner stopping after `dotnet restore` or `dotnet test`

Question

I am new to CI and tried to add the following yaml to our project.

image: microsoft/dotnet:latest

stages:
  - test

test: 
  stage: test
  before_script:
    - 'echo Stage - Test started'
    - 'dotnet tool install dotnet-reportgenerator-globaltool --tool-path tools'
  script:  
    - 'cd "./My Project"'  
    - 'dotnet test --settings:./Settings/CodeCoverage.runsettings --collect:"XPlat Code Coverage"'
    - './tools/reportgenerator "-reports:./Tests/*/TestResults/*/coverage.cobertura.xml" "-targetdir:Reports_Coverage" -reportTypes:TextSummary'
    - 'cat ./Reports_Coverage/Summary.txt'
  after_script:
    - 'echo Stage - Test finished'

On the job I get the following output:

You can invoke the tool using the following command: reportgenerator

I tinkered around a little bit and realized, that this minified yaml also fails:

image: microsoft/dotnet:latest

stages:
  - test

test: 
  stage: test
  before_script:
    - 'cd "./My Project"'  
    - 'dotnet restore'
  script:  
    - 'dotnet test --no-restore'

This generates an equal output, except it stops at dotnet restore. I honestly don't know what to do, since this is the most minified version of a test I found. Did I mess up something within the project, or is the problem within the GitLab Runner itself?

Not a real solution, but I found the issue behind this. You can set the verbosity level of the dotnet test command (documentation). While doing so, I found out that you obviously cannot run a WPF project within a Linux based GitLab Runner.
