Unable to cast COM object of type 'System.__ComObject' to interface type 'AXVLC.IVLCPlaylist'. (in c# app)

[Astarael]

Hi,

I'm testing an application at work built in C# using win forms.
It's working fine on my colleague who built it's PC but not on mine.
I have the latest version of VLC.

I get the following error when trying to load videos into the players

************** Exception Text **************
System.InvalidCastException: Unable to cast COM object of type 'System.__ComObject' to interface type 'AXVLC.IVLCPlaylist'. This operation failed because the QueryInterface call on the COM component for the interface with IID '{54613049-40BF-4035-9E70-0A9312C0188D}' failed due to the following error: No such interface supported (Exception from HRESULT: 0x80004002 (E_NOINTERFACE)).
at System.StubHelpers.InterfaceMarshaler.ConvertToManaged(IntPtr pUnk, IntPtr itfMT, IntPtr classMT, Int32 flags)

Anyone any ideas - I'm thinking maybe the version of VLC? I'll know more maybe when she's back in tomorrow but right now I can't tell you anymore about the codebase.
Thanks!

Please file a bug, or use 2.1.5, for now.

Same issue here.
Updated to 2.2.1 and got the same error.

Has a bug report been filed for this? If so, is it being addressed? Because it still exists in 2.2.3, we're being forced to use 2.1.5 across all applications.

Do this issue also appear for you in new projects, or only in already existing ones?

For already existing projects: Try to delete or rename the folders /obj and /bin in your project folder. At next compilation time, Visual Studio will re-generate some libraries to access to VLC.
