.NET Core Multi-Stage Dockerfile with Test and Code Coverage in Azure Pipelines

I read a great blogpost recently by my friend and fellow MVP Jakob Ehn. In this post he outlines how he created a multi-stage Dockerfile to run .NET Core tests. I've always been on the fence about running tests during a container build -

A/B Testing with Azure Linux Web Apps for Containers

Running the New DotNet Core VSTS Agent in a Docker Container

This week I finally got around to updating my VSTS extension (which bundle x-plat VersionAssembly and ReplaceTokens tasks) to use the new vsts-task-lib, which is used by the new DotNet Core vsts-agent. One of the bonuses of the new agent is that it can

DotNet Core, VS 2015, VSTS and Docker

I unashamedly love Docker. Late last year I posted some thoughts I had on Docker DevOps. In this post I’m going to take a look at Docker DevOps using DotNet Core 1.0.0, Docker Tools for Visual Studio, Docker for Windows and
