Build .NET Core 3.0 on Azure Pipelines

Question

Yes, I know .NET Core 3.0 is still in preview. I would like to build this on Azure Pipelines.

Is there an easy way to do this?

Currently getting this error:

/usr/share/dotnet/sdk/2.2.105/Sdks/Microsoft.NET.Sdk/targets/Microsoft.NET.TargetFrameworkInference.targets(137,5): error NETSDK1045: The current .NET SDK does not support targeting .NET Core 3.0. Either target .NET Core 2.2 or lower, or use a version of the .NET SDK that supports .NET Core 3.0.

edit

I found official documentation about this:

You can install the .Net core SDK 3.0 during the pipeline with .Net Core SDK Installer task:

- task: UseDotNet@2
  displayName: 'Install .net core 3.0 (preview)'
  inputs:
    packageType: sdk
    version: '3.0.100-preview6-012264'
    installationPath: $(Agent.ToolsDirectory)/dotnet

I specified the last preview version of .net core sdk 3.0, you can put an earlier version, you can find here the versions list.

Another option is to specify 3.0.x and enable the preview versions:

version: 3.0.x
includePreviewVersions: true

Installation results:
