avolaande has uploaded a patch.
Description:
Made version 2.6 that includes next changes:
* Feature: Visual Studio 2012 solution file and settings there to generate VS 2012 supported plug-in.
* Feature: Now should this plug-in support also Visual Studio BizTalk 2010 project that is configured to work like ".csproj" project type. Not to much tested but currently seems works well. Maybe You accept to add these minor changes also into official source :-)
Here is full source with changes uploaded if someone intrested to try this.
