How to disable SmartScreen (safebrowsing in edge) on C# Selenium Edge Chromium?

Question

I'm trying to run some selenium C# end-to-end tests on Edge Chromium browser. One of the tests does a download check, basically it downloads a xml file and check whether it exists in the downloaded location.

I'm using Microsoft.Edge.SeleniumTools EdgeOptions to construct options for the EdgeDriver.

But the issue right now is that Edge blocks downloads.

Tried different sorts of things but none of them worked.

Same issue can be solved on Chrome by disabling "safebrowsing" on UserProfilePreferences in ChromeOptions.

I know for a fact that SmartScreen does the blocking, if that is so is there any profile preference that I can use to disable SmartScreen ?

Or any other workaround to force download without the block would be very helpful.

For testing purposes, I suggest you create HashMap objects and try to set Edge preferences like below.

static void Main(string[] args)
 {
            HashMap<String, Object> edgePrefs = new HashMap<String, Object>();
            edgePrefs.put("profile.default_content_settings.popups", 0);
            edgePrefs.put("profile.default_content_setting_values.notifications", 2);       
            edgePrefs.put("profile.default_content_setting_values.automatic_downloads" , 1);        
            edgePrefs.put("profile.content_settings.pattern_pairs.*,*.multiple-automatic-downloads",1);

            var options = new EdgeOptions();
            egdeOptions.setExperimentalOption("prefs",edgePrefs);
            options.UseChromium = true;
            options.BinaryLocation = @"C:\Program Files (x86)\Microsoft\Edge\Application\msedge.exe";   // Here add the Edge browser exe path.
            var driver = new EdgeDriver(@"Edge_driver_path_here...", options); // Here modify the selenium web driver path.
            driver.Navigate().GoToUrl("http://website_URL_here..."); 
            driver.FindElementById("lnk1").Click();
          
}

If the issue persists then I suggest you set the default download directory like below.

options.AddUserProfilePreference("download.default_directory", @"D://Folder1");

See whether it help to download the file.

I was trying to find the answer with the usage of W3C WebDriver Protocol, but it seems like the only possible way is to turn off XML Edge SmartScreen policies using Windows Registry:

public void SetEdgeXmlDownloadPolicy()
        {
            var keyName = @"HKEY_CURRENT_USER\Software\Policies\Microsoft\Edge\ExemptDomainFileTypePairsFromFileTypeDownloadWarnings";
            var valueName = "AllowXmlDownload";
            var valueData = @"{""domains"": ["" * ""], ""file_extension"": ""xml""}";
            var currentValue = Registry.GetValue(keyName, valueName, string.Empty).ToString();
            if (currentValue == string.Empty || !currentValue.Contains("xml"))
                Registry.SetValue(keyName, valueName, valueData, RegistryValueKind.String);
        }
