Trigger Multiple pipelines using another pipeline (same Project) - Azure DevOps

Question

How to create a pipeline (YAML configuration, not classic) that is able to trigger multiple pipelines, in the same Project, inside Azure DevOps Organization ?

Trigger all the pipelines in the list, at the same time, no matter the result of the build(s) of each one of them, fail or pass.

Thank You.

To trigger one pipeline after another, configure a pipeline resource trigger.

For example, if pipeline A should trigger pipelines B, C and D (in the same project) you can define the following trigger (or similar) in each one of them:

# Resource to define in pipelines B, C and D

resources:
  pipelines:
  - pipeline: source # pipeline alias
    source: A # source (aka triggering) pipeline name
    trigger: true # trigger a run when any run of A pipeline completes

You can optionally specify branch filters, stage filters and tag filters:

# Resource to define in pipelines B, C and D

resources:
  pipelines:
  - pipeline: source # pipeline alias
    source: A # source (aka triggering) pipeline name
    trigger:
      branches: # Branches to include and/or exclude
        include:
        - main
        - develop
        - features/*
        exclude:
        - features/experimental/*
      tags: # List of tags that when matched will trigger the pipeline. 
      - release25
      stages: # List of stages that when complete will trigger the pipeline. 
      - build
