I've referenced the MSMQ v3 Object Library in a VS2010 C# project only to get:

System.Runtime.InteropServices.COMException (0x80040154): Retrieving the COM class factory for component with CLSID {0188401C-247A-4FED-99C6-BF14119D7055} failed due to the following error: 80040154 Class not registered (Exception from HRESULT: 0x80040154 (REGDB_E_CLASSNOTREG)).

I've registered the library the reference points to:

regsvr32 C:\windows\system32\mqoa.dll

What am I missing? Assuming this works, what will I have to do at deployment to ensure the app will run on other machines with MSMQ installed?

Dynamic Type to do away with Reflection

as seen on West-Wind - Search for 'West-Wind'
The dynamic type in C# 4.0 is a welcome addition to the language. One thing I’ve been doing a lot with it is to remove explicit Reflection code that’s often necessary when you ‘dynamically’ need to walk and object hierarchy. In the past I’ve had a number of ReflectionUtils that used string based expressions… >>> More
