Wed, May 1 2013 9:01
The problem I have been working on a project that contains SharePoint 2010 WSP packages and a MSI distributed WPF application. These projects are all in a single solution with their unit tests. I have been getting a problem with our TFS 2012.2 build system, all the projects compile but at the test point I get the unhelpful TF900546: An unexpected error occurred... Read More...

Type ‘InArgument(mtbwa:BuildSettings)’ of property ‘BuildSettings’ errors in TFS 2012 RTM builds
Thu, Aug 30 2012 9:30
I posted a while ago that you saw errors when trying to edit TFS 2012RC build process templates in VS 2012RC if the Visual Studio class library project you were using to manage the process template editing was targeting .NET 4.5, it needed to be 4.0. Well with Visual Studio 2012 RTM this is no longer the case, in fact it is the other way around. I have recently... Read More...

Getting Typemock Isolator running within a TFS 2012 build
Sat, Aug 4 2012 6:01
I have posted in the past about getting Typemock Isolator to function within the TFS build process . In TFS 2008 it was easy , you just ran a couple of MSBUILD tasks that started/stopped the Typemock Isolator inception process (the bit that does the magic other mocking frameworks cannot do). However with TFS 2010’s move to a windows workflow based build model... Read More...

Two problems editing TFS2012 build workflows with the same solution
Mon, Jul 30 2012 14:27
Whilst moving over to our new TFS2012 system I have been editing build templates, pulling the best bits from the selection of templates we used in 2010 into one master build process to be used for most future projects. Doing this I have hit a couple of problems, turns out the cure is the same for both Problem 1 : When adding custom activities to the toolbox Visual... Read More...

TFS Build error, 'Index (zero based) must be greater than or equal to zero and less than the size of the argument list” when building XAML projects
Wed, May 9 2012 10:45
We had an interesting issue of late building a Surface2 application solution within a TFS 2010 build system. The solution built fine in VS2010 on both my development PC and also using VS2010 on my TFS build box (both Windows 7 64bit PC), so I know I had all the right SDKs in place. However if I built it via TFS 2010 Team Build I got the error App.xaml (136):... Read More...

Access denied when running a command with InvokeProcess in a TFS team build
Fri, Nov 18 2011 10:33
When you are trying to run a command line tool via the InvokeProcess activity in a TFS 2010 Team build you might see the somewhat confusing ‘Access denied’ error. There appears to be no more detail in the log. I have found that this is usually down to a type on the filename property of the activity. It should be set to something like “c:\my tools\tool.exe” but... Read More...

Using Nuget and TFS Build 2010
Mon, Oct 17 2011 5:38
At one of our recent events I was asked if I had any experience using Nuget within a TFS 2010 build. At the time I had not, but I thought it worth a look. For those of you who don’t know Nuget is a package manager that provides a developer with a way to manage assembly references in a project for assemblies that are not within their solution. It is most commonly... Read More...
