The mad coder has blogged about a BizTalk 2010/ Visual Studio 2008 Solution template based on Dan Rosanova’s book – BizTalk Patterns 2010
If you try to install this on BizTalk 2013/ Visual Studio 2012 you get this error.
After modifying the source.extension.vsixmanifest as described here and recompiling the mad coder solution gives a VSIX, that installs the Organized BizTalk Solution extension into Visual studio 2013.
This extension can be downloaded from here. It is only compatible with the Professional edition of Visual Studio 2012
