## Prerequisites

To develop C# applications for YugabyteDB, you need the following:

- **.NET SDK**

  Install .NET SDK 6.0 or later. To download it for your supported OS, visit [Download .NET](https://dotnet.microsoft.com/en-us/download).

- **Create a C# project**

   For ease-of-use, use an integrated development environment (IDE) such as Visual Studio. To download and install Visual Studio, visit the [Visual Studio Downloads](https://visualstudio.microsoft.com/downloads/) page.

  - To create a C# project in Visual Studio, select [Console Application](https://docs.microsoft.com/en-us/dotnet/core/tutorials/with-visual-studio?pivots=dotnet-6-0) as template when creating a new project.
  - If you are not using an IDE, use the following dotnet command:

    ```csharp
    dotnet new console -o new_project_name
    ```

- **YugabyteDB cluster**

  - Create a free cluster on YugabyteDB Aeon. Refer to [Use a cloud cluster](/stable/quick-start-yugabytedb-managed/). Note that YugabyteDB Aeon requires SSL.
  - Alternatively, set up a standalone YugabyteDB cluster by following the steps in [Install YugabyteDB](/stable/quick-start/macos/).
