Overview of this book

In C# 8.0 and .NET Core 3.0 – Modern Cross-Platform Development, Fourth Edition, expert teacher Mark J. Price gives you everything you need to start programming C# applications.

Publishing your applications for deployment

There are three ways to publish and deploy a .NET Core application. They are:

  • Framework-dependent deployment (FDD).
  • Framework-dependent executables (FDEs).
  • Self-contained.

If you choose to deploy your application and its package dependencies, but not .NET Core itself, then you rely on .NET Core already being on the target computer. This works well for web applications deployed to a server because .NET Core and lots of other web applications are likely already on the server.

Sometimes, you want to be able to give someone a USB stick containing your application and know that it can execute on their computer. You want to perform a self-contained deployment. While the size of the deployment files will be larger, you'll know that it will work.
