A .NET app in App Engine is configured using an
file, that contains CPU, memory, network and disk resources, scaling, and other
general settings including environment variables.
Specify all the runtime configuration for your .NET app, including
versions and URLs, in the
app.yamlfile. This file acts as a deployment descriptor of a specific service version. You must first create the
app.yamlfile for the
defaultservice of your app before you can create and deploy
app.yamlfiles for additional services.
You can specify a unique name for your
app.yaml files, but then you must
specify the file name with the deployment
as well. For example, if you name your
app.flexible.yaml, then you must deploy your app using either:

app.yamlfiles in your app, see Structuring Web Services. Depending on the complexity of your app's service, you might only need to define a few elements in the corresponding
app.yamlfile. The following example demonstrates what a simple .NET app might require in the flexible environment:
runtime: aspnetcore env: flex # This sample incurs costs to run on the App Engine flexible environment. # The settings below are to reduce costs during testing and are not appropriate # for production use.

My__Greeting: Hello AppEngine!
app.yamlfile is in the YAML format.
