XAML Issues

Hi,
I'm not sure if other people have had this issue, but I've been running into errors in a couple XAML files when trying to compile MissionPlanner on Windows in Visual Studio. The errors are as follows:

Error 1 Unknown build error, ''clr-namespace:TfsBuild;' mapping URI is not valid. Line 1 Position 1611.'
C:\Users\Jason\Dropbox\misc\Lymbo_Jason\Visual Studio Projects\MissionPlanner-master\MissionPlanner-master\ExtLibs\GeoUtility\BuildProcessTemplates\DefaultTemplate.11.1.xaml Line 1 Col 1611 MissionPlanner

Error 2 The tag 'Activity' does not exist in XML namespace 'http://schemas.microsoft.com/netfx/2009/xaml/activities'. Line 1 Position 35.
C:\Users\Jason\Dropbox\misc\Lymbo_Jason\Visual Studio Projects\MissionPlanner-master\MissionPlanner-master\ExtLibs\GeoUtility\BuildProcessTemplates\LabDefaultTemplate.11.xaml Line 1 Col 35 MissionPlanner

Error 3 Unknown build error, ''clr-namespace:TfsBuild;' mapping URI is not valid. Line 1 Position 1172.'
C:\Users\Jason\Dropbox\misc\Lymbo_Jason\Visual Studio Projects\MissionPlanner-master\MissionPlanner-master\ExtLibs\GeoUtility\BuildProcessTemplates\UpgradeTemplate.xaml Line 1 Col 1172 MissionPlanner

Any help or previous experience would be appreciated. Thank you!

Start by reproducing the Visual Studio build on Windows and inspect the three named files under ExtLibs/GeoUtility/BuildProcessTemplates: DefaultTemplate.11.1.xaml, LabDefaultTemplate.11.xaml, and UpgradeTemplate.xaml. Compare the reported namespace and Activity errors with the project’s build setup. Done means these XAML errors no longer occur during compilation.
