//The rules Visual Studio uses to resolve references are as follows:
//1. Assemblies that are visible in the project as project items or links are considered.
// If Visual Studio .NET 2005 with MSBuild is being used, these must have a Build Action of Content or None.
//2. Assemblies in Reference Path directories are considered.
// These are stored in .user files and are visible under project properties.
//3. The HintPath of the reference is considered.
// This is a path to the referenced assembly (relative to the project).
// It is stored when the reference is originally created.
//4. Assemblies in the native framework directory are considered
// (e.g., \Windows\Microsoft.NET\Framework\v1.1.4322 for Visual Studio .NET 2003).
//5. Assemblies in the registered assembly folders are considered.
// These are the directories discussed in the last section about adding assemblies to the list of .NET assemblies.
// If Visual Studio .NET 2005 with MSBuild is being used,
// HKLM\Software\Microsoft\ .NETFramework\v2.x.xxxxx\AssemblyFoldersEx will be considered first.
//6. If Visual Studio .NET 2005 with MSBuild is being used and the assembly has a strong name,
// Visual Studio will look in the GAC for the assembly.
