I've got problems building the latest release (it's actually the first release I've tried to build).
It's your typical "The type or namespace name 'BindingGroup' could not be found (are you missing a using directive or an assembly reference?) " error.
That type is found in "PresentationFramework.dll", but I have a reference to that assembly (run time version v2.0.50727).
I have .net 3.5SP1 installed, but there is no 3.5 version of PresentationFramework.dll in C:\Program Files\Reference Assemblies\Microsoft\Framework\v3.5.
Is that the correct assembly?
