## Use with Azure Functions
### Visual Studio or Visual Studio Code
If you're using Visual Studio or Visual Studio Code, and C# programming language to develop functions, make sure that you're using the latest [Microsoft.Azure.WebJobs.Extensions.EventGrid](https://www.nuget.org/packages/Microsoft.Azure.WebJobs.Extensions.EventGrid/) NuGet package (version **3.3.1** or above).
In Visual Studio, use the **Tools** -> **NuGet Package Manager** -> **Package Manager Console**, and run the `Install-Package` command (`Install-Package Microsoft.Azure.WebJobs.Extensions.EventGrid -Version 3.3.1`). Alternatively, right-click the project in the Solution Explorer window, and select **Manage NuGet Packages** menu to browse for the NuGet package, and install or update it to the latest version.
In VS Code, update the version number for the **Microsoft.Azure.WebJobs.Extensions.EventGrid** package in the **csproj** file for your Azure Functions project.
