This is a .NET tool to detect whether any files affecting a given project or projects in a repository were changed in a commit or pull request.
The idea is that you can have a single Git repo with one or more .NET solutions, and determine whether the CI/CD pipeline needs to be run for a subset of projects within that repo. For example, you might have a web application, an API and a NuGet package all in the same repo. If you just change a button style in the web application, you probably don't want to release a new version of the API and NuGet package.
You can install the tool locally
