TypeLoadException in Windows store app

Question

I am using a Winmd (Windows Runtime Component) in a windows store app. When I try to instantiate a type that is defined the in the winmd, I get the following exception:

 System.TypeLoadException was unhandled by user code
  HResult=-2146233054
  Message=Requested Windows Runtime type 'SmartTech.BrokeredProxy.EnterpriseServer' is not   registered.
  Source=mscorlib
  TypeName=SmartTech.BrokeredProxy.EnterpriseServer
    InnerException: System.Runtime.InteropServices.COMException
       HResult=-2147221164
       Message=Class not registered (Exception from HRESULT: 0x80040154 (REGDB_E_CLASSNOTREG))
       ErrorCode=-2147221164
       InnerException:

I added all references that I need and I made the appropriate changes in the Manifest file . Did I miss something? Any one has an idea what causes this?

This happens when you use the .winmd file for the component to compile your program but forget to package it along with your other files. A Store app must include **all** of the runtime components it uses. — Hans Passant, May 13 '14 at 22:23
@HansPassant It appears the OP is using a [brokered runtime component](https://msdn.microsoft.com/en-us/windows/uwp/winrt-components/brokered-windows-runtime-components-for-side-loaded-windows-store-apps) given the `BrokeredProxy.EnterpriseServer'. Thus the app should be sideloaded. — ZX9, Oct 18 '16 at 12:07

for non-winrt apps, i know this error normally points to the component not being registered. i.e. regsvr32 "path of the component"

but for a win 8 app, not sure it is completely applicable.

The other case, i have hit similar issues is due to 32 bit/any cpu conflicts.

the component might be a 32 bit component and Visual Studio might be compiling with the 'Any CPU' setting. Try changing the 'Target CPU' to x86 from project properties and see if the issue occurs.

Project -> Properties -> Build tab -> Platform Target -> Any CPU to x86

Also, you can check the specific target cpu for each project in your solution by right-clicking on your solution in Solution Explorer -> **Properties**-> **Configuration Properties**-> **Configuration** — ZX9, Oct 18 '16 at 12:13
