When you open the build process template, it takes 15 – 30 seconds until it opens. When you are in the process of creating your custom build process template, this can be very frustrating. Thanks to Ed Blankenship how has found a little trick to speed up the opening of the template. It now only takes a few seconds.

1. Create a file called empty.xaml and place the following text in it:
   <Activity http://www.edsquared.com/ct.ashx?id=1746c587-59ce-45eb-85af-8ea167862617&url=http%3a%2f%2fschemas.microsoft.com%2fnetfx%2f2009%2fxaml%2factivities">http://schemas.microsoft.com/netfx/2009/xaml/activities">
   </Activity>
2. Open this file in Visual Studio.
3. In the toolbox panel, add a new tab called “Team Foundation Build Activities”.  Note that it is important to get the tab name correct because if it is not correct then the activities will be reloaded.
4. Inside the new tab, right click and select “Choose Items”
5. Click the Browse button
6. Load the file C:\Windows\Microsoft.NET\assembly\GAC_MSIL\Microsoft.TeamFoundation.Build.Workflow\v4.0_10.0.0.0__b03f5f7f11d50a3a\Microsoft.TeamFoundation.Build.Workflow.dll
7. Click OK to add the toolbox items to the tab.
8. Create another new tab called “Team Foundation LabManagement Activities”.
9. Inside the new tab, right click and select “Choose Items”
10. Click the Browse button
11. Load the file C:\Windows\Microsoft.NET\assembly\GAC_MSIL\Microsoft.TeamFoundation.Lab.Workflow.Activities\v4.0_10.0.0.0__b03f5f7f11d50a3a\Microsoft.TeamFoundation.Lab.Workflow.Activities.dll
12. Click OK to add the toolbox items to the tab.
