'RealtimeStreaming.Network.Listener' is not registered.

[jmichelD5T]

Hello,
When running the desktop server application, I receive the following error when I try to start the server:

System.TypeLoadException
HResult=0x80131522
Message=Requested Windows Runtime type 'RealtimeStreaming.Network.Listener' is not registered.
Source=mscorlib
StackTrace:

at System.Threading.ExecutionContext.Run(ExecutionContext executionContext, ContextCallback callback, Object state, Boolean preserveSyncCtx)

at System.Threading.ThreadPoolWorkQueue.Dispatch()

Inner Exception 1:
COMException: Class not registered (Exception from HRESULT: 0x80040154 (REGDB_E_CLASSNOTREG))

I encountered no build errors when building the source code or the desktop server projects, but I encountered various warnings related to WinRT when building the source. I built both projects for Release/x64. The server program immediately crashes after continuing execution past this error.

If anyone has any ideas on why this might occur, please let me know!

Hello @jmichelD5T
I had the same problem and here are two possible solutions that i found:

COM components need to be registered to Windows registers to be used in other applications. That is one way to solve that error.

Another way is to configure the project to use the Registration Free COM Interop method. An example can be found here.
Basically:

1. Add Microsoft.VCRTForwarders NuGet Package
2. Create an Application Manifest File
3. Add an entry in the created manifest file for each imported dll files and each class, like:

<file name="RealtimeStreaming.dll">
    <activatableClass
      name="RealtimeStreaming.Network.Listener"
      threadingModel="both"
      xmlns="urn:schemas-microsoft-com:winrt.v1" />
  </file>

Hello @matealex,
I have a similar problem with "'RealtimeStreaming.Network.Connector' is not registered." I tried to register it following the information provided in the page linked by you, but I couldn't register it.
I try the command regasm RealtimeStreaming.winmd, but i get an error every time saying:
RegAsm : error RA0000 : Could not load file or assembly ("RealtimeStreaming.winmd") or one of its dependencies.. (translated)
I would greatly appreciate any help.
