Release Notes

microsoft/playwright-dotnet (Microsoft.Playwright)

v1.60.0

💬 Custom assertion messages

Expect() overloads now accept a custom message that is prepended to any failure, giving extra context in test reports:

await Expect(page.Locator("#status"), "Should be logged in").ToBeVisibleAsync();

When the assertion fails, the message is prefixed:

Should be logged in
Locator expected to be visible

🌐 HAR recording on Tracing

Tracing.StartHarAsync() / Tracing.StopHarAsync() expose HAR recording as a first-class tracing API, with the same Content, Mode and UrlFilter options as RecordHar:

await context.Tracing.StartHarAsync("trace.har");
var page = await context.NewPageAsync();
await page.GotoAsync("https://playwright.dev");
await context.Tracing.StopHarAsync();

🪝 Drop API

New Locator.DropAsync() simulates an external drag-and-drop of files or clipboard-like data onto an element. Playwright dispatches dragenter, dragover, and drop with a synthetic [DataTransfer] in the page context — works cross-browser and is great for testing upload zones:

await page.Locator("#dropzone").DropAsync(new() {
    Files = new FilePayload() {
        Name = "note.txt",
        MimeType = "text/plain",
        Buffer = Encoding.UTF8.GetBytes("hello"),
    },
});

await page.Locator("#dropzone").DropAsync(new() {
    Data = new Dictionary<string, string> {
        ["text/plain"] = "hello world",
        ["text/uri-list"] = "https://example.com",
    },
});

🎯 Aria snapshots

• Expect(page).ToMatchAriaSnapshotAsync() now works on a Page, in addition to a Locator — equivalent to asserting against Page.Locator("body").
• New Boxes option on Locator.AriaSnapshotAsync() / Page.AriaSnapshotAsync() appends each element's bounding box as [box=x,y,width,height], useful for AI consumption.

New APIs

Browser, Context and Page

• Event Browser.Context — fired when a new context is created on the browser.
• BrowserContext now mirrors lifecycle events from its pages: BrowserContext.Download, BrowserContext.FrameAttached, BrowserContext.FrameDetached, BrowserContext.FrameNavigated, BrowserContext.PageClose, BrowserContext.PageLoad.
• Page now implements IAsyncDisposable — pages can be used with await using for automatic cleanup.

Locators and Assertions

• New option Description in Page.GetByRole() / Locator.GetByRole() / Frame.GetByRole() / FrameLocator.GetByRole() for matching the accessible description.
• New option Pseudo in Expect(locator).ToHaveCSSAsync() reads computed styles from ::before or ::after.
• New option Style in Locator.HighlightAsync() applies extra inline CSS to the highlight overlay, plus new Page.HideHighlightAsync() to clear all highlights.

Network

• WebSocketRoute.Protocols returns the WebSocket subprotocols requested by the page.
• New option NoDefaults in BrowserType.ConnectOverCDPAsync() disables Playwright's default overrides on the default context (download behavior, focus emulation, media emulation), so attaching to a user's daily-driver browser doesn't disturb its state.

Errors

• New WebError.Location.

🛠️ Other improvements

• Trace Viewer adds a pretty-print toggle for JSON / form request and response bodies in the network details panel.

Breaking Changes ⚠️

• Docker image bumped to .NET SDK 10; no more docker images are published for Ubuntu Jammy.
• Removed long-deprecated Handle option on BrowserContext.ExposeBindingAsync and Page.ExposeBindingAsync.

Browser Versions

• Chromium 148.0.7778.96
• Mozilla Firefox 150.0.2
• WebKit 26.4

This version was also tested against the following stable channels:

• Google Chrome 147
