Installing the .NET Tools

To get all the .NET tools that you need pre-installed in your Gitpod workspaces, use the following base image in your .gitpod.yml:

language icon language: 
yml
image: gitpod/workspace-dotnet

If your project requires a GUI or Virtual Desktop, please use this image instead:

language icon language:

This will give you a full GUI Virtual Desktop for your .NET application! The Virtual Desktop will be running on port 6080.

Compiling .NET Code in Gitpod

To compile your C# or F# Code in Gitpod, run dotnet build <FILE>, where <FILE> is the path to the C# or F# project file or .NET solution file you want to compile.

Running .NET Code in Gitpod

To run your code after it has been compiled run dotnet <FILE> where <FILE> is the path to the EXE file you want to run. You can also run application with dotnet run <FILE> where <FILE> is the path to the C# or F# project file you want to compile and run.

Running .NET Code in watch-mode

Alternatively, you can also run your application in so-called watch-mode. In such configuration the application will recompile and rerun itself every time you save any source file belonging to the project. To run your code in watch-mode use dotnet watch --project <FILE> run where <FILE> is the path to the C# or F# project file you want to compile and run.
