The Vonage Video API Client build DLLs (opentok.dll and MFCapturer.dll) are not being added to the ClickOnce project. The NuGet package does not copy them as dependencies for OpenTokNET.dll.
- Video API
- Windows SDK
Manually copying the DLLs to the output directory will fix the issue. Both the x86 and x64 versions of the DLLs should be copied.
