Make sure to re-compile your WebView2 app after updating the WebView2 SDK NuGet package. The WebView2 team recommends the following:

  • Use the Canary preview channel of Microsoft Edge (which includes the WebView2 Preview Runtime) when you do early testing and development using a Prerelease version of the WebView2 SDK package.

    Canary is the recommended preview channel, because it ships at the fastest cadence and has the newest APIs.

    Prerelease testing of WebView2 SDKs uses a preview channel of Microsoft Edge (Beta, Dev, or Canary), which includes the WebView2 Preview Runtime. See Prerelease testing using preview channels.

  • Use the Evergreen WebView2 Runtime when you use a release version of the WebView2 SDK package.

Updating the Runtime

WebView2 changes may require an update to the WebView2 Runtime, the WebView2 SDK, or both. Most new APIs require both Runtime and SDK updates.

WebView2 shares code and binaries with the Microsoft Edge browser, and is released around the same time. As a result, WebView2 Runtime releases generally also include Microsoft Edge updates.

To obtain a WebView2 Preview Runtime, use the following combination:

  • A Prerelease version of the WebView2 SDK.
  • A preview channel of Microsoft Edge (containing the WebView2 Preview Runtime) on your development client.
