Project Description
MSBuild Task makes it easier with maintaining app.config and web.config across multiple projects, and build configurations.

Create one app.config/web.config template and share it across multiple projects with different configurations for each build target.

Supports
* Recursive configuration transformations, i.e. one configuration variable referencing another variable
* Nested configurations - i.e. one configuration inheriting from another
* Simple value transformations
* Full element transformations

  <!--$(Diagnostics)-->
  <!--$(ServiceModel)-->
  <system.web>
    <compilation debug="$(Debug)"/>
  </system.web>
