问题
I'm having an issue with my deployment in my Azure Pipeline for my .Net Core API deployment.
The build is failing because recently the API was upgraded from .Net Core 3.1 to .Net Core 5.0.
How do I upgrade the version in the deployed API?
The build is failing because of it.

Azure doesn't come with .Net 5 just yet. Insert a new step at the beginning of your pipeline to install .Net 5:
- task: UseDotNet@2
displayName: .Net 5
inputs:
version: 5.0.100
Or, if you are using the classic graphical interface, add the step Use .NetCore and make sure you use the right version. As of today it is 5.0.100.
