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?

Using Git submodules in (private) Azure DevOps repositories

I often use Git Submodules in my repositories, it’s a handy way to have external source code in your repo, without having to worry much about the external updates and source management (you can just checkout, pull etc as every normal git repo).

Often the external sources are hosted in public GitHub repos, without any need to authenticate.
You create .gitmodules file look like:†

[submodule "DbConnector"]
	path = DbConnector
	url = https://github.com/chaconinc/DbConnector

And with a few more command you are ready to go.

Lastly I wanted to use submodules between my private Azure DevOps repositories in the same Azure DevOps Project.
So I added the submodule with its full path, like:

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:
