9/27/2023 0 Comments Microsoft edge webview2![]() ![]() When we try to block these calls WebView2 won't load page contents. This would raise a concern as our customers need to open up the firewall for these calls.Ģ. Is there a way to avoid these calls?Īny insights would be greatly appreciated. Windows-wpf your posted links it looks like you are seeing this behavior because of SmartScreen. I found below information from the documents. Microsoft Defender SmartScreen protects users while they browse the Internet by using a reputation check system. Microsoft Edge passes relevant information about the URL or file to the Microsoft Defender SmartScreen service to start the reputation check. The check compares the website or file against dynamic lists of sites and files that are known to be dangerous. All requests to the Microsoft Defender SmartScreen service are made with TLS encryption. The service returns the results of the reputation check, which might lead to Microsoft Edge showing a warning for the site or file. These results are stored locally on the device. The Microsoft Defender SmartScreen service stores data about reputation checks. As new sites are identified, the service adds to a dynamic database of known malicious URLs and files. This data is stored on secure Microsoft servers and is only used for Microsoft security services. This data will never be used to identify or target users in any way. ![]() I only define a user data folder path.Clearing browsing cache clears all locally stored Microsoft Defender SmartScreen URL data. In detail: We just use CreateCoreWebView2EnvironmentWithOptions and pass a nullptr to the options and to browserexecutable folder. Crash dumps show that the Close function of the ICoreWebView2Controller is called. But starting from today a reproducible crash is reported from many customers. The implementation calls CreateCoreWebView2EnvironmentWithOptions. We don't ship any additional runtime, we just include the WebView2Loader.dll into our setup. In fact when ICoreWebView2Controller::Close is called. Symptoms: We get a crash when the WebView2 window is closed. It seams that in the current WebView2 that is online published by Microsoft is a bug. ![]()
