Versions of the Functions runtime support specific versions of .NET. To learn more about Functions versions, see Azure Functions runtime versions overview. Version support also depends on whether your functions run in-process or isolated worker process.
Note
To learn how to change the Functions runtime version used by your function app, see view and update the current runtime version.
The following table shows the highest level of .NET or .NET Framework that can be used with a specific version of Functions.
