This is a release candidate for WinAppDriver v1.2 which introduces compatibility fixes with WebDriverIO as well as new capabilities, defined below:

1. The ms:experimental-webdriver capability enables experimental features and optimizations - for this release, enabling this capability will provide performance improvements with XPath and improve overall element handling. C#: appCapabilities.SetCapability("ms:experimental-webdriver", true);

2. The ms:waitForAppLaunch capability enables WinAppDriver to wait for a defined amount of time after an app launch is initiated prior to attaching to the application session. The limit for this is 50 seconds. C#: appCapabilities.SetCapability("ms:waitForAppLaunch", "25"); to add app delay of 25 seconds.

As with the previous WinAppDriver v1.1 release, it is recommenced to use the WinAppDriver NuGet package to take full advantage of the advanced input with the Actions API.
