Hi Rakki,

Did you get a chance to try steps from Prakash's post and walkthrough.

Okay - I changed it to have the ProgID, but still I've the same error coming up.

Still no luck :(

If you are building the managed provider and look at the sample code in the walkthrough there is a Program ID:

[Guid("D5178953-96A0-4ebd-B511-024897DA2C09")]
    [ProgId("SamplePlaylistProvider.ProviderSample")]
    [ComVisible(true)]
    public class PlaylistProvider : IPlaylistProvider
    {
        IPlaylistInfo IPlaylistProvider.GetPlaylistInfo(IPlaylistRequestInfo requestInfo)
        {
            String path = requestInfo.Path;
            String name = path.Substring(path.LastIndexOf('/') + 1);
            name = name.Substring(0, name.LastIndexOf(".")) + ".wmv";
            return new PlaylistInfo(Advertisement, name);

Yes, you should build a managed dll and then regasm it. The following walkthrough steps do that (you can skip to the second step if you use shipped playlisthandler.dll)

Building a .net based provider

Building a .net based provider is a two step process1.

Create a Type library (you can skip this step if you have access to released playlisthandler.dll)

midl /I<Path to Web Playlists Include> playlistprovider.idl /tlb playlistprovider.tlb /win32
midl /I<Path to Web Playlists Include> playlistprovider.idl /tlb playlistprovider.tlb /x64
where <Path to Web Playlist Include> is the location where unzipped the Interface files too.

Import Types into as assemblely

1. Use the .tlb created in step 1

tlbimp /out:<outputdirectory>\<outputprovidertypelib.tlb> /namespace:<Provider Namespace> <handler reference>

(E.g., tlbimp /out:E:\myprovider\playlistprovder.dll /namespace:Microsoft.Web.Media.Playlist.Provider E:\myprovider\playlistprovider.tlb )

2. Use the released playlisthandler.dll

tlbimp /out:<outputdirectory>\<outputproviderdll.dll> /namespace:<Provider Namespace> <path to playlist handler>\playlisthandler.dll

(E.g., tlbimp /out:E:\myprovider\playlistprovder.dll /namespace:Microsoft.Web.Media.Playlist.Provider E:\myprovider\playlisthandler.dll )

Compile the custom provider with reference to assembly created in step2
Csc.exe /noconfig /nowarn:1701,1702 /errorreport:prompt /warn:4 /define:TRACE
/reference:..\playlistprovder.dll
/reference:C:\Windows\Microsoft.NET\Framework\v2.0.50727\System.dll
/debug:pdbonly /filealign:512 /optimize+
/out:obj\Release\providersample.dll
/target:library AssemblyInfo.cs PlaylistProvider.cs

When you register a register a provider, what is that “ProgramID”? COM GUID? I’m just using that sample which was provided in the site and it has the below: [Guid("D5178953-96A0-4ebd-B511-024897DA2C09")] I just used the same Guid there while creating a new provider. I’ve just added the same ProviderSample.cs file to my App_Code folder. But, I get 500 Error with below: Detailed Error Information

Module	PlaylistHandler
Notification	ExecuteRequestHandler
Handler	PlaylistHandler-D5178953-96A0-4ebd-B511-024897DA2C09-rpl
Error Code	0x800401f3

That error code corresponds to CO_E_CLASSSTRING # Invalid class string. While registering the provider, what should I register? Should I create a DLL for my .cs and use regAsm to register it? I’m confused L Any clue?
