Zoom does not actively enhance the interfaces in the C# wrapper. This wrapper is provided as a reference and will not be actively supported by Zoom. If you would like to contribute, please contact us. Thanks!

Download the Zoom SDK

Login to the Zoom App Marketplace using your Zoom account, click the Develop option in the dropdown on the top-right corner and select Build App. Next, click the Create button and provide the required details if you haven’t already created an SDK app. If you previously created an SDK app on the Marketplace, click the View here option and navigate to the Download page. Click Windows(C#) to download the Windows(C#) SDK.

Please note that:

  • Currently the C# wrapper only supports x86
  • The wrapper DLL is located at zoom-c-sharp-wrapper-master\bin\zoom_sdk_dotnet_wrap.dll

Configure wrapper

After you downloaded the wrapper, follow the below steps to configure your wrapper:

  1. Download the latest Zoom Windows SDK and unzip all files.
  2. Unzip the C# wrapper you downloaded above.
  3. Copy the “h” folder in the Windows SDK into the C# wrapper folder
  1. Copy all files in the bin folder in the Windows SDK into the bin folder in the C# wrapper:
  1. Navigate to the zoom_sdk_c_sharp_wrap folder and launch the project by clicking zoom_sdk_c_sharp_wrap.sln file.
  2. Change the project setting to be “Build

Run demo

  1. Open the demo project by clicking zoom_sdk_demo.csproj in the zoom_sdk_demo folder.
  2. Change the project’s solution configuration to Release
  3. Change the project’s solution platform to x86
  4. Build and run

Adding new interface in C# wrapper

Since the C# wrapper is a community project, it may not include all interfaces available in the Windows SDK. However, as long as an interface is available in the Windows SDK, developers may configure the C# wrapper and make any interfaces available in the C# wrapper.

This guide will take AskAttendeeToStartVideo as an example.

Note: If your goal is to recompile the C# wrapper without adding new interfaces, just follow Step 1-3.


  • C# wrapper
  • Visual Studio 2019 or later

Steps to add an interface

  1. Download the latest C# wrapper from App Marketplace

  2. Go to the zoom_sdk_c_sharp_wrap folder and open the solution file zoom_sdk_c_sharp_wrap.sln in Visual Studio:

  1. Once the project is opened, you will see the project zoom_sdk_dotnet_wrap, which is the C# wrapper that we will be modifying:

Rebuild the solution if your goal is just to recompile the C# wrappers.

  1. To add AskAttendeeToStartVideo, navigate to the IMeetingVideoControllerDotNetWrap class and add the new AskAttendeeToStartVideo interface:
  1. Add the same interface in the private ref class in the meeting_video_dotnet_wrap.h

  2. Go to meeting_video_dotnet_wrap.cpp and add the AskAttendeeToStartVideo function:

  1. Rebuild the C# wrapper project. Then you can use this interface in your project.

You may repeat the same steps for all other interfaces that you could not find in the C# wrapper.
