           Summary: xbuild fails if an unmanaged library is located in a
                    project reference path
    Classification: Mono
           Product: Mono: Tools
           Version: 2.4.x
          Platform: x86
        OS/Version: Windows XP
            Status: NEW
          Severity: Normal
          Priority: P5 - None
         Component: xbuild

(libOpenMetaverse is successfully compiling with xbuild except for this last
issue)

When the assembly reference path (in a Visual Studio project file) for a
project contains an unmanaged (C/C++) .dll, it looks like xbuild will end up
calling System.Reflection.AssemblyName.GetAssemblyName() on it even if no
projects are referencing that library. This results in the error and stack
trace below:

:  error : Error while building
C:\Code\OpenMetaverse\trunk\OpenMetaverseCore\Op
enMetaverseCore.csproj

Reproducible: Always

Steps to Reproduce:
1. Compile a solution with xbuild and confirm that it works
2. Put an unmanaged .dll in your project assembly reference path
3. Try to compile with xbuild again and observe that it fails
Actual Results:  
Should completely ignore unmanaged binaries that are not referenced by any
project files

Expected Results:  
Printed out the error shown above
