I've run into the persistent problem that Intellisense is consistently failing, and I'm hoping someone can help.

We have a large multi project solution that relies on a custom rake build script. For this we've been using a template csproj file which looks about like the following:

<Project DefaultTargets="Build" xmlns="http://schemas.microsoft.com/developer/msbuild/2003">

</ItemGroup>
<Import Project="$(MSBuildBinPath)\Microsoft.CSharp.targets" />
<Target Name="Build">

The rake command outputs the compiled dlls, and pdb files into ../pkg/bin/ relative to the project file.

Intellisense fails to pick up on any user coded classes, or anything from the referenced libraries. Any ideas?
