## Installation

Install Microsoft.Playwright package from NuGet in Visual Studio or from the CLI in your project root directory:

```sh
dotnet add package Microsoft.Playwright
```

## Usage

```csharp
using Microsoft.Playwright;
using System.Threading.Tasks;

class Example
{
    public static async Task Main()
    {
        using var playwright = await Playwright.CreateAsync();
        await using var browser = await playwright.Chromium.LaunchAsync();
        // Create pages, interact with UI elements, assert values
    }
}
```

## First script

In our first script, we will navigate to `whatsmyuseragent.org` and take a screenshot in WebKit.

```csharp
using Microsoft.Playwright;
using System.Threading.Tasks;

class Example
{
    public static async Task Main()
    {
        using var playwright = await Playwright.CreateAsync();
        await using var browser = await playwright.Chromium.LaunchAsync();
        var page = await browser.NewPageAsync();
        await page.GotoAsync("whatsmyuseragent.org");
        await page.ScreenshotAsync(path: "screenshot.png");
    }
}
```

By default, Playwright runs the browsers in headless mode. To see the browser UI, pass the `headless: false` flag while launching the browser. You can also use [`option: slowMo`] to slow down execution. Learn more in the debugging tools [section](./debug.md).

```csharp
await playwright.Firefox.LaunchAsync(headless: false, slowMo: 50);
```

## Record scripts

Command Line Interface [CLI](./cli.md) can be used to record user interactions and generate C# code.

```sh
# FIXME:
```

## System requirements

The browser binaries for Chromium, Firefox and WebKit work across the 3 platforms (Windows, macOS, Linux):

### Windows

Works with Windows and Windows Subsystem for Linux (WSL).

### macOS

Requires 10.14 (Mojave) or above.

### Linux

Depending on your Linux distribution, you might need to install additional
dependencies to run the browsers.

:::note
Only Ubuntu 18.04 and Ubuntu 20.04 are officially supported.

See also in the [Command Line Interface](./cli.md#install-system-dependencies)
which has a command to install all necessary dependencies automatically for Ubuntu
LTS releases.
