When the HIDLib used in C#/Visual Studio 2008 the function HIDManager.GetDetails() fails with the exception

System.InvalidCastException: Unable to cast object of type 'System.Collections.ObjectModel.ReadOnlyCollection`1[BlueNinjaSoftware.HIDLib.HIDDevice]' to type 'System.Collections.Generic.List`1[BlueNinjaSoftware.HIDLib.HIDDevice]'.
at BlueNinjaSoftware.HIDLib.HIDManagement.GetDevices() in C:Blue Ninja SoftwareCodeCommonLibrariesHIDLibsrcHIDManagement.vb:line 31

no matter what the left side of the assignment is (List<HIDDevice> devices, var devices, IList<HIDDevice> )

sorry, the function in question is HIDManager.GetDevices()....

Thanks for taking the time to report this. The actual enumerable type returned is Collections.ObjectModel.ReadOnlyCollection(Of HIDDevice), but we haven't come across the same casting issue when using a List or IEnumerable type. I will try to duplicate this issue this afternoon and let you know what I come across.
