Hi All,

I am developing a desktop wpf application which connects windows 8 tablet with BLE device over Bluetooth. Win8 metro app supports apis for Bluetooth via Windows.Devices.Bluetooth.Rfcomm namespace as given in the link https://code.msdn.microsoft.com/windowsapps/Bluetooth-communication-7130c260

I tried porting the same to Win 8 desktop application by changing targetplatform as 8 in Project settings and adding references to dlls as given in https://software.intel.com/en-us/articles/using-winrt-apis-from-desktop-applications
but get the following exception on executing the application

An exception of type 'System.BadImageFormatException' occurred in but was not handled in user code

Additional information: Could not load file or assembly 'System.Runtime.WindowsRuntime, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' or one of its dependencies. Reference assemblies should not be loaded for execution. They can only be loaded in the Reflection-only loader context. (Exception from HRESULT: 0x80131058)

Mine is a 32 bit system and on changing the build configuration to x86 also getting the same error.Please let me know what could be the issue.
