DotNetBrowser 1.21.1: Improvements and fixes

Please welcome DotNetBrowser 1.21.1 containing useful fixes and improvements.


  • We have added the sign to the GZipCompress.exe utility, which will reduce the number of errors with firewalls, antiviruses and other security software, when launching applications, containing DotNetBrowser.
  • The embedding process of the WinFormsBrowserView component in a WPF application got better. Now pop up windows are available upon embedding.  


Fixed issues:

  • The InvalidCastException occurring because of the new PermissionRequest.PermissionType values in Chromium 69.
  • The InvalidOperationException occurring with the Channel already closed exception if registering a protocol handler for two or more BrowserContext instances.
