Running .NET 6 Isolated Azure Functions in Azure

In this post, let's see how we can run .NET 6 Isolated (Out-of-process) Azure Functions in Azure. 

If you are new to .NET 6 Isolated (Out-of-process) Azure Functions, you can read this post: .NET 6 and Azure Functions.

Let's start off by Creating a Function App. Here you need to select these options.

• Runtime Stack: .NET
• Version: 6

Create .NET 6 Function App

Now you can follow the Wizard and create the Function App. Once the Function App is created, we need to deploy a .NET 6 Isolated (Out-of-process) Azure Function App. I am not going to show that step, let's assume we just deployed a sample .NET 6 Isolated (Out-of-process) Azure Function App.

And now, when we navigate into the Function App from Azure, we should be seeing an error, something like this: Microsoft.Azure.WebJobs.Script: Did not find functions with language [dotnet].

Microsoft.Azure.WebJobs.Script: Did not find functions with language [dotnet].

And the reason for this is, by default when Azure creates .NET 6 Function App, it sets FUNCTIONS_WORKER_RUNTIME as dotnet.

FUNCTIONS_WORKER_RUNTIME

In order to run Azure Functions in Isolated (Out-of-process) mode, we need to set FUNCTIONS_WORKER_RUNTIME to dotnet-isolated.

And that should be it. Now the Azure Function is all set up to run in Isolated (Out-of-process) mode.

Hope this helps.

Happy Coding.
