C# Find all tests in a solution

Are there any technologies I can use to find all tests in a solution that are annotated as a test ([TestMethod], [Fact], [Theory]...)?

Context: I am quite new to all this but attempting to iron out a continuous deployment strategy. I want to find and run all tests in a solution during/following a release process. These are not build dependent unit tests, these are part of end to end solution tests.

Please let me know if my thinking is away from the right track.
