Using .net core 3.0 in Azure DevOps

Monday, 23 September 2019 | 0 Comments | words | minutes | Permalink

During todays livestreamed ".net conf 2019", Microsoft announced that .net core 3.0 has been released.

The release includes a plethora of changes and improvements, however one thing that is yet to be completed is official Azure DevOps pipeline images containing the 3.0 SDK.

For Kenc.ACMELib I updated my Azure DevOps pipeline today to build using .net core 3.0. These are the steps involved.

Edit pipeline

1. Navigate to pipelines in the menu
2. Click the pipeline you wish to edit
3. Add a new task for "Use .net"
4. Set version to 3.0.x
5. Re-arrange the tasklist to include the installation before any task that uses .net core 3.0

note: After installing .net core 3.0, I had to repeat the steps to install the other versions I use in the pipeline! (2.0.x, 2.1.x)

If using YAML:

steps:
- task: UseDotNet@2
  displayName: 'Use .Net Core sdk 3.0.x'
  inputs:
    version: 3.0.x

Trigger new build to test the pipeline

With version 3.0 installed, the build completes
