VSTS Countdown Widget now supports on-premise TFS

without comments

We’ve had the new extensibility on VSTS for some time now, including the ability to create dashboard widgets. With TFS 2015 update 2 the same extensibility became available to our on-premise TFS and with TFS 2015 update 3 we now also have support for custom dashboard widgets.

Give this we just released an update to the Countdown Widget which adds support for on-premise TFS installation, which has been a much asked for capability.

Get the latest version from the Visual Studio Marketplace:

If you are curios how the widget is implemented then I recommend taking a look at the articles Wouter de Kort and I wrote a while back:

Retain builds from Release Management

without comments

When releasing with Microsoft Release Manager “vNext” the linked builds don’t automatically get marked as retained forever. If you want to be able to re-deploy released builds you want to ensure the builds are not deleted by retention polices. It’s a good idea to let the release definition take care of this (at some point, perhaps in the release to production stage) and mark the released builds as retained.

Here’s a PowerShell script that gets the builds used in the release and set the “keep forever” flag on the builds:


You can use this from your release definition either by including the script in one of the build artifacts and reference it or using an in-line PowerShell script step:


Note: the script above works with an on-prem TFS (using default credentials), if you want to use it with VSTS you need to include an authentication header instead and pass a personal access token.

$username = “”
$basicAuth = (“{0}:{1}” -f $username,$password)
$basicAuth = [System.Text.Encoding]::UTF8.GetBytes($basicAuth)
$basicAuth = [System.Convert]::ToBase64String($basicAuth)
$headers = @{Authorization=(“Basic {0}” -f $basicAuth)}

Then replace the –UseDefaultCredentials with -headers $headers.

Get the complete script here (rename to .ps1).

Versioning files in TFS Build (vNext)

without comments


In my DevOps and Continuous Delivery presentations I’m always including a step in the build process where source files are updated with the current build number. This gives us an easy way to correlate the produced package to the build it came from, which is great for traceability.

Enough people have asked for the script so I feel I should post it here. It’s really nothing special, just a lightly customized version of the original sample script Andy Lewis wrote a long time ago. The sample comes from mine and Jakob’s book on Continuous Delivery so make sure to get a copy if you want more context.

The script will apply a version to the source files, for instance updating AssemblyInfo attributes like this:


Our script will also update the version number for database projects (DACPAC packages) and Android manifest files. It’s easy to extend the script to do the same for Wix projects (MSIs) or C++ (RC) files following the same principles.

All you need to do to add it to your source code repository and use a PowerShell build step to run the script. In our example you need to pass the build source directory and the build number to the task:


Download the complete script here (and rename it to .ps1).

Continuous Delivery with Visual Studio ALM 2015 Book Released!

with one comment

Just in time for the Connect(); event the new book I’ve been working on together with Jakob Ehn has been released. This book gives hands-on examples on how to implement a continuous delivery process using the latest Microsoft tools. It’s been great fun to have had the opportunity to work with all the new versions of the product and it’s really great to see how well the different tools fit together and help us build DevOps and continuous delivery solutions much quicker (and better!) than before. If you want to learn more about the new build, test and release management systems there should be a lot of useful content here.

Building good software is challenging. Building high-quality software on a tight schedule can be close to impossible. Continuous Delivery is an agile and iterative technique that enables developers to deliver solid, working software in every iteration. Continuous Delivery practices help IT organizations reduce risk and potentially become as nimble, agile, and innovative as startups. Although not sufficient in itself, having a powerful set of tools that lets you implement practices such as Continuous Integration, deployment pipelines, and release management certainly will help you go a long way. With the Visual Studio 2015 ALM suite of tools there is now a very compelling offering that covers all areas when it comes to implementing Continuous Delivery. Also, as this book will show, these tools are open and extensible by nature, meaning that you don’t have to use every part of the suite if you don’t want to.

This Book

  • Explains the concepts of Continuous Delivery.
  • Shows how to implement a Continuous Delivery process using
    a modern development platform based on Visual Studio 2015,
    Team Foundation Server, Visual Studio Online, and Microsoft
  • Gives you practical guidance and ready-to-use recipes to help you
    build your own Continuous Delivery pipeline.

What You Will Learn

  • What Continuous Delivery is and how to use it to create better
    software more efficiently using Visual Studio 2015.
  • How to use Team Foundation Server 2015 and Visual Studio
    Online to plan, design, and implement powerful and reliable
    deployment pipelines.
  • Detailed step-by-step instructions for implementing Continuous
    Delivery on a real project

Table of Content

  • Chapter 1: Introduction to Continuous Delivery
  • Chapter 2: Overview of Visual Studio 2015 ALM
  • Chapter 3: Designing an Application for Continuous Delivery
  • Chapter 4: Managing the Release Process
  • Chapter 5: Source Control Management
  • Chapter 6: PowerShell for Deployment
  • Chapter 7: Build Automation
  • Chapter 8: Managing Code Quality
  • Chapter 9: Continuous Testing
  • Chapter 10: Building a Deployment Pipeline
  • Chapter 11: Measure and Learn

Automatically update test plan with build number, take 2

without comments

A while back I wrote a PowerShell script to automatically update a test plan with the latest build number (

This script works well as long as the build server has permission to read and update test plans. But in some environments (such as when running on a hosted build agent in VSO) we need to do an explicit authentication. The solution I’ve choosen is to simply pass in credentials to the script and do an authentication before using the TFS API.

The script now takes two optional parameters if you want to authenticate, username and password, and you can just pass them in from the build definition.  You can use ether basic authentication and pass both or use the safer option and pass a Personal Access Token (PAT) in which case you only pass the PAT as the password.

Here’s an example where you go to manage your credentials in Visual Studio Online. First go to your profile:


From the Security tab you can either create a Personal Access Token:


Press Add to create an access token:


Copy the PAT (it cannot be retrieved later):


If you want to use basic authentication go to the Alternate authentication section and fill in the secondary username and password:


With this you are ready to use the script. Download the latest version from here:

Check in the script to Source control and update a Xaml build definition to use the script. In the following example I’ve used a PAT and only pass the token as the password:


Check out the old post if you want a step-by-step instruction on how to setup the build and test plan.

Build Status Badge for TFS 2015 and VSO

with 4 comments

A while back I wrote a post about how we can create a build bagde in TFS just like some of the other CI server can. It was actually really simple but since it was a custom extension it needed to be deployed outside of TFS, which of course is a bit of a pain. 

With TFS 2015 RC and the new build system I’m happy to see there is now a new feature that let’s you get a build badge automatically!

To get a build badge you just need to enable it on the build vNext build definition:


Note how nice the url to the badge is presented:


With this you can easily include the build badge in any web page. I really like the new Markdown support so I would include it in your wiki by simply point to in the badge url:


Save and it renders nicely like this:


So with this my suggestion on Uservoice can be closed.
