# Try the demo app

<!-- WARNING: THIS FILE WAS AUTOGENERATED! DO NOT EDIT! -->

Now that you've downloaded and set up the sample app, it's time to bring it to life.

## Build and run the demo

Build the default SDK for Windows demo app.

1. Open the demo app in your IDE of choice.
    1. In Visual Studio, go to the `demo` folder.
    1. Open the `sdk_demo.vcxproj` file.
2. Set your build configuration. In Visual Studio, set the **Solution Configuration** to **Release**.
3. Define your architecture. In Visual Studio, set the **Solution Platform** to either **X86** (for 32-bit systems) or **X64** (for 64-bit systems).
4. Build and run.

Build the default SDK for Windows demo app with the C# wrapper.

1. Open the demo app in your IDE of choice.
    1. In Visual Studio, go to the `zoom_sdk_demo` folder.
    1. Open the `zoom_sdk_demo.csproj` file.
2. Set your build configuration version. For example, in Visual Studio, set the **Solution Configuration** to **Release**.
3. Define your architecture. In Visual Studio, set the **Solution Platform** to either **X86** (for 32-bit systems) or **X64** (for 64-bit systems).
4. Build and run.

## Play with the app

Now let's play around with the demo application.

Launch the app from your IDE to open the demo app. In Visual Studio, press **Local Windows Debugger**. When you launch the demo app, it opens a series of screens asking for some information. Depending on which wrapper you're using, these screens will be different.

For this part, you'll need a meeting ID number and meeting passcode from a pre-created Zoom meeting.

1. On the first dialog, when asked to enter a domain, enter `https://zoom.us` and press **SetDomain**.

    ![Screenshot of the demo app's first dialog, titled Window. It has the Zoom logo, a field for the domain, a Custom UI checkbox, and a Set Domain button.](/img/1615493065904.png)

> Do not use a raw IP address as the web domain. That exposes your app to vulnerability issues. To learn more, see our [security practices](/docs/meeting-sdk/security-practices/#raw-ip-vulnerability-issue).

2. On the next dialog, enter your [JWT token](/docs/meeting-sdk/auth/) and press **Auth**.

3. On the final dialog, go to the **Only Join** tab and enter your meeting number, your display name for the meeting, and the meeting password. Then press **Join**.

    ![Screenshot of the Join Only tab of the demo app's third dialog. This Join Only tab shows the Zoom logo, a field for the Meeting ID, a field for your User Name or Display Name, a field for the Meeting Password, and a Join button.](/img/1615493265636.png)

    If all went well, you'll see the meeting window.

4. On the first dialog, when asked to enter your **App Token**, enter your [JWT token](/docs/meeting-sdk/auth/).
5. On the second dialog, enter a **UserName**, **UserID** (email), your **ZAK Access Token**, and the **Meeting Number**.
6. Select **Start**.

    If all went well, you'll see the meeting window.

Congratulations! You have set up, built, and run the demo app and used it to join a pre-existing Zoom meeting. Explore all the features of our Meeting SDK, such as Share, Chat, Record, or Closed Caption.

This is what the Meeting SDK for Windows looks like in a Windows application.
