Instructions

For general instructions to run the examples, see the README in the dotnetv3 folder.

Some projects might include a settings.json file. Before compiling the project, you can change these values to match your own account and resources. Alternatively, add a settings.local.json file with your local settings, which will be loaded automatically when the application runs.

After the example compiles, you can run it from the command line. To do so, navigate to the folder that contains the .csproj file and run the following command:

dotnet run

Alternatively, you can run the example from within your IDE.
