Description

We should only run tests if there's some change to test. We gain nothing by running tests on PRs/pushes where no tested examples changed & doing so wastes time & resources.

We can update our GitHub Actions workflows to do this. See Example including paths in the GitHub docs.

e.g. for .NET we could update /.github/workflows/dotnet-core.yml as in the following:

(can we combine the `paths` definitions for `push` and `pull_request` somehow?)

on: 
  push: 
    branches: [ master ]
    paths: 
      - 'examples/dotnet/**'
  pull_request: 
    branches: [ master ]
    paths: 
      - 'examples/dotnet/**'
