Bonjour SDK for Windows 8.1

Question

I installed both Bonjour SDK for Windows v2.0.4 and Bonjour 3 for Windows 8 and 8.1 from Apple's website on my Windows 8.1 machine. When I try to use the Bonjour package in my C# code, the package is not recognized and I can't use the SDK. Any ideas why this would happen?

Edit: Turns out it was because Interop.Bonjour.dll was not among the References, so I added it and now I don't get the error. However, when I try to use a class of Bonjour package, like below:

DNSSDService service = new DNSSDService();

I get an exception with the message:

Creating an instance of the COM component with CLSID {24CD4DE9-FF84-4701-9DC1-9B69E0D1090A} using CoCreateInstanceFromApp failed due to the following error: 80040154 Class not registered (Exception from HRESULT: 0x80040154 (REGDB_E_CLASSNOTREG)). Please make sure your COM object is in the allowed list of CoCreateInstanceFromApp.

My code is written for a Windows 8.1 Metro app if that helps.
