Working with a DTE.Project and an MSBuild Project

I'm working on an automation project that does a bunch of work with a DTE Project, and for the most part, the DTE Project exposes everything I need....

Except for the "internal" settings of the project file itself, ie - the info contained within:

<PropertyGroup Condition=" '$(Configuration)|$(Platform)' == 'Debug|AnyCPU' ">
.... blah blah blah...
</PropertyGroup>

On the other hand, instantiating an MSBuild Project allows me to go after and play with all the underlying goodness using the GetEvaluatedProperty() and SetProperty() methods.

My dilemna is trying to save any changes I made via the MSBuild project - as you would expect, the VS IDE advises me that something (ie: the MSBuild Project) has changed my project outside the environment, and "would I like to reload" This is causing havoc on my automation logic.

Is there a way I can manipulate the data within this property group (using MSBuild or other) without having the IDE get upset (ie: can I somehow effect the change using the DTE.Project )

Following is some sample code:

private void PlayWithProjectStuff(EnvDTE.Project dteProject)
{

//Some hard code to get us going...

Microsoft.Build.BuildEngine.Engine.GlobalEngine.BinPath = @"C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727";

Microsoft.Build.BuildEngine.Project msBuildProject =

new Microsoft.Build.BuildEngine.Project();

msBuildProject.Load(dteProject.FullName);

//works great..

string data = msBuildProject.GetEvaluatedProperty("Something");

//also works great..

msBuildProject.SetProperty("Something", "SomeValue");

//and kaboom...

msBuildProject.Save(dteProject.FullName);

}

-- TIA for any help.
