How do you use GitHub Actions for continuous integration and deployment with .NET Core?

GitHub Actions is a powerful tool for implementing continuous integration and deployment workflows. Here are the basic steps for using GitHub Actions with .NET Core:

1. Create a GitHub repository for your .NET Core project and push your code to it.
2. Create a new workflow file (e.g. dotnet-core.yml) in the .github/workflows directory of your repository.
3. Define the triggers for the workflow (e.g. push, pull_request) and the operating system (e.g. Ubuntu, Windows) you want to use for your builds.
4. Set up your build and test steps in the jobs section of your workflow file. For example, you might use the dotnet CLI to restore dependencies, build the project, and run tests.
5. Add deployment steps to your workflow file if you want to deploy your application after successful builds. You can use tools like Azure Web Apps or Docker containers to deploy your .NET Core application.
6. Commit and push your changes to your repository to trigger the GitHub Action.

GitHub Actions provides a wide range of pre-built actions for common tasks like building, testing, and deploying .NET Core applications. You can also create your own custom actions if you need more specialized functionality.

In addition to GitHub Actions, there are other popular CI/CD tools that can be used with .NET Core, including Azure DevOps, Jenkins, and Travis CI. The specific steps for using these tools will depend on the tool itself and how it integrates with .NET Core.
