I have been doing some work on vNext Release Management; I managed to waste a good hour today with a stupid error. In vNext process templates you provide a username and password to be used as the Powershell remoting credentials (in the red box below) My Powershell script also took a parameter username, so this was provided as a custom configuration too (the green box). This was the issue. Not unsurprisingly having two parameters with the same name is a problem. You might get away with it if they are the same value (I did on one stage, which caused more confusion), but if they differ (as mine did in my production stage) the last one set wins, which meant my remote Powershell returned the error ...

I will be speaking at Leeds DevOps on the 21st of July on the subject of Desired State Configuration (DSC). ‘In the Windows world, due to its API based architecture, deployment is too often not as simple as copying an EXE and updating a text configuration file. Desired State Configuration is an attempt to ease the pain we suffer in this space. Providing a set of tools that can be leveraged by any set of deployment tools whether in a Windows or heterogeneous environment. In this session we will look at what DSC is, what resource are available and how to write your own’. ...

Update 21 Aug 2015 - This post contains all the basic information, but there is an improved PowerShell script discussed in Using Release Management vNext templates when you don’t want to use DSC scripts – A better script Many web sites are basically forms over data, so you need to deploy some DB schema and something like a MVC website. Even for this ’bread and butter’ work it is important to have an automated process to avoid human error. Hence the rise in use of release tools to run your DACPAC and MSDeploy packages. ...

With the help of the Release Management team at Microsoft I now have a working REST based automated TFS Build to Release Management pipeline. Previously we were using a TFS automated build and then manually triggering our agent based Release Management pipeline. When we moved to a vNext PS/DSC based RM pipeline I took the chance to automate the link using REST via a PowerShell script to trigger the initial deployment. However, I hit problem, first with a stupid 401 permission error and later with a much stranger 500 internal server error. ...

Whilst setting up Application Insights on one of our web sites I hit a problem. The target site appeared to be working OK, but if I setup a ping test it failed. Digging into the failure, as with much of Application Insights just keep clicking to go deeper, I found the issue was that a CSS file was failing to load. Presumably on this Umbraco site the CSS file is meant to be loaded for the site but none of the styles are actually used, hence the site renders OK. ...

Today was my day for semi annual Media Center (MCE) problems. As usual they seemed to start with an unexpected power issue, a local power cut, maybe the answer is a UPS for the TV setup? Once the PC was rebooted it had forgotten it had any tuners. If I tried to view live TV or re-setup the TV signal it just hung with a spinning ‘toilet bowl of death’ cursor. Corrupt TV data DB I suspect, I have seen it before ...

Had a strange issue today while editing our standard TFS 2013 XAML build process template to add an optional post drop script block to allow a Release Management pipeline to be triggered via REST. Our standard template includes a block for enabling and disabling Typemock, after editing our template to add the new script block (nowhere near the Typemock section) our builds failed with the error TF215097: An error occurred while initializing a build for build definition BMISS.Expenses.Main.CI: Exception Message: Cannot set unknown member 'TypeMock.TFS2013.TypeMockStart.DisableAutoLink'. (type XamlObjectWriterException) Exception Stack Trace: at System.Xaml.XamlObjectWriter.WriteStartMember(XamlMember property) It took ages to find the issue, we hunted for badly formed XAML, but the issue turned out to be that when ever we opened the template in Visual Studio 2013 it added the highlighted property ...

Recently whilst at a clients one of our consultants came across an interesting issue; the client was using Selenium to write web tests, they wanted to trigger them both from Microsoft Test Manager (MTM) as local automated tests, and also run them using BrowserStack for multi browser regression testing. The problem was to import the tests into MTM they needed to be written in MsTest and for BrowserStack nUnit. As they did not want to duplicate each test what could they ? ...
