Hi John I'm encountering the same issue. Did you find a solution?

It is compiling and running in my dev environment using .NET Core 3.0 but behind my Azure build Pipeline I get the following error

It was not possible to find any compatible framework version [/home/vsts/work/1/s/blah.csproj]
error : The specified framework 'Microsoft.NETCore.App', version '2.1.0' was not found.
error : - The following frameworks were found: [/home/vsts/work/1/s/blah.csproj]
error : 3.0.0 at [/opt/hostedtoolcache/dotnet/shared/Microsoft.NETCore.App]
error : [/home/vsts/work/1/s/blah.csproj]

workaround is to make sure 2.x is on the build box as well. I changed my deploy script to this and it worked in the interim.

- task: UseDotNet@2

    version: '2.1.x'
- task: UseDotNet@2
  inputs:
    packageType: 'sdk'
    version: '3.0.x'
