Add real lead-in for EnhancedSecurityModeState, and check heading.
There was a problem hiding this comment.
Heading is correct.
Here is the lead-in/description for Enhanced Security Mode State.
Enhanced Security Mode State:
The EnhancedSecurityModeState property on CoreWebView2Profile controls whether Enhanced Security Mode is enabled or disabled for all WebView2 instances associated with a profile.
When enabled, Enhanced Security Mode disables JavaScript Just-in-Time (JIT) compilation and enables additional operating system protections, reducing attack surface at the cost of some JavaScript performance.
The default value is `Disabled`. Changes apply immediately to new navigations; existing pages require a reload.
This setting does not persist and resets when the profile is destroyed and recreated.

We don't need to provide the candidates; this API was already there in Phase 1 for WebView2 devs to be already familiar with the methods.
But just as an FYI for you, the candidates are:
CoreWebView2ServiceWorker.PostWebMessageAsJsonCoreWebView2ServiceWorker.PostWebMessageAsStringCoreWebView2DedicatedWorker.PostWebMessageAsJsonCoreWebView2DedicatedWorker.PostWebMessageAsStringCoreWebView2ServiceWorker.WebMessageReceivedCoreWebView2DedicatedWorker.WebMessageReceivedchrome.webview.postMessage
This one is not:
chrome.webview.postMessageWithAdditionalObjects

| * Fixed double character in UWP. | ||
| * Fixed Caption controls background color setting API. After this change, apps will also have to intercept the close call and handle themselves to close the app. | ||
| * Fixed forwarding of network events for iframe, where the iframe had its own isolated CDP session. | ||
| * Improved error handling when Post Message is called on a service worker. |

There was a problem hiding this comment.
We don't need to explain much for this bug. This one liner is enough.
But just for your reference, the error handling is applicable just on these two:
CoreWebView2ServiceWorker.PostWebMessageAsJson
CoreWebView2ServiceWorker.PostWebMessageAsString
i.e. on Service Worker.
Doesn't yet apply on Dedicated Worker.

There was a problem hiding this comment.
There is a breaking change this Prerelease as well. Please find the details below:
I have created the issue and provided the link as well.
EnhancedSecurityModeLevel replaced by EnhancedSecurityModeState
The EnhancedSecurityModeLevel property on CoreWebView2Profile controls whether Enhanced Security Mode (ESM) is enabled or disabled for all WebView2 instances associated with a profile. This property has been renamed to EnhancedSecurityModeState to more clearly communicate the state of Enhanced Security Mode.
Before this change: The CoreWebView2Profile.EnhancedSecurityModeLevel property used the CoreWebView2EnhancedSecurityModeLevel enum with values Off and Strict to control Enhanced Security Mode.
After this change: The CoreWebView2Profile.EnhancedSecurityModeState property uses the CoreWebView2EnhancedSecurityModeState enum with values Disabled and Enabled:
-
Disabled— Enhanced Security Mode is disabled (replacesOff). -
Enabled— Enhanced Security Mode is enabled. Disables JavaScript Just-in-Time (JIT) compilation and enables additional operating system protections (replacesStrict).
The EnhancedSecurityModeLevel property and CoreWebView2EnhancedSecurityModeLevel enum are deprecated. Replace all usage of EnhancedSecurityModeLevel with EnhancedSecurityModeState in your WebView2 application.
