// Description: This is a MSBuild task which generates a temporary target assembly 
//              if current project contains a xaml file with local-type-reference.
// 
//              It generates a temporary project file and then call build-engine
//              to compile it.
//
//              The new project file will replace all the Reference Items with the 
//              resolved ReferenctPath, add all the generated code file into Compile
//              Item list. 
// 
// History:
//  05/10/05: weibz   Created.

// 
// 
// Description: This is a MSBuild task which generates a temporary target assembly 
//              if current project contains a xaml file with local-type-reference.
// 
//              It generates a temporary project file and then call build-engine
//              to compile it.
//
//              The new project file will replace all the Reference Items with the 
//              resolved ReferenctPath, add all the generated code file into Compile
//              Item list. 
// 
// History:
