.NET frameworks supported by Azure App Service

Question that bugs me

Which .NET frameworks are supported by Azure App Service?

This question has bugged me all the time! Especially whenever I have started working on any new migration project. Unfortunately, I have not found a definitive list in the Azure documentation that talks about it. Microsoft keeps on adding support for new .NET frameworks though.

Recently they announced support for .NET 4.8 for Azure Web Apps
I decided to dig and find answer once for all.


There must be some method to the madness, you know!

Let’s cook!

  • From an existing web app deployed in Azure, go to the Kudu portal.
  • In the Debug Console -> CMD : go to D:\Program Files (x86)\Reference Assemblies\Microsoft\Framework.NETFramework
  • This will show the list of .NET frameworks installed for the Azure Web App.

Wrap Up!

As of now, Azure Web App/Website supports 4.0, 4.5, 4.5.1, 4.5.2, 4.6, 4.6.1 ,4.6.2 ,4.7 ,4.7.1 ,4.7.2 ,4.8 .NET frameworks. I am sure this will keep on changing as and when new version of .NET becomes available!
