Using Azure Managed Identity with .Net Core on Azure DevOps Agents

During my last project I needed to run some integration test written in .Net Core 2.2 in an Azure Devops Pipeline.

The code needed some secrets from an Azure KeyVault and doing some other stuff on other Azure Resources using Azure Managed Identities for authentication on them.

In .Net Core you can easily accomplish this using the AppAuthentication Nuget library.

Here an example how to use this library for getting secrets etc.. from the KeyVault.

To run this code you need an Azure infrastructure where Managed Identities is enabled, like a VM, Azure Web App/Function App etc….

So, how can you run this code on Azure DevOps agents?

Solve “System.Threading.Tasks.TaskCanceledException : The operation was canceled. ” on Ubuntu 18.04 in .Net Core 2.2

I am running some .Net Core 2.2 (at the moment of writing version 2.2.301) integration test in Azure DevOps (ADO) running on my private Linux Ubuntu 18.04 agents.
The tests are quiet simple, just call an internally exposed Rest API through Azure API Management.
Because the APIM is running internally the endpoint are using self-signed SSL certificates generated with an internal Root Certificate.

During the runs in ADO I was experiencing the following error: 

Error Message:
   System.Threading.Tasks.TaskCanceledException : The operation was canceled.
  Stack Trace:
