.NET Core 3.1 updates on Google Cloud

.NET Core 3.1 was released on December 3rd, 2019 and is a LTS release, supported for three years.

In Google Cloud, you could already deploy .NET Core 3.1 containers in Cloud Run (see cloud-run-dotnetcore-31) and also in App Engine flexible environment with a custom runtime.

We recently extended .NET Core 3.1 support in a couple of ways:

1. Cloud Shell now supports .NET Core 3.1.
2. App Engine flexible environment runtime now supports .NET Core 3.1.

.NET Core 3.1 in Cloud Shell

Inside Cloud Shell, you can see the latest 3.1.301 version:

I love how easy it is to deploy and run containerized ASP.NET Core apps on App Engine (flex). So much so that, I created a Cloud Minute recently to show you how, here it is.

It basically involves 3 steps:

1. Create your ASP.NET Core app using dotnet command line tool inside Cloud Shell and publish your app to get a self-contained DLL.
2. Containerize your app by creating a Dockerfile, relying on the official App Engine image and pointing to the self-contained DLL of your app.
3. Create an app.yaml file for App Engine and use gcloud to deploy to App Engine.

That’s it! If you want to go through these steps yourself, we also have a codelab for you that you can access here.
