title: Xamarin.Messaging.Broker wants firewall access
body: <p>After installing VS2019 16.5.1 and 16.5.2 I receive a message that Windows Defender has locked some features of <code>Xamarin.Messaging.Broker</code> and asking if I should allow it.</p>
  
  <p>Normally I would as it seems to be part of Visual Studio but this executable is located in my appdata\local\temp file, which I would not expect it to be. Searching the net for info about this yields little in the way of good information.</p>
  
  <p>Does anyoe know what it does and why on earth would you put an exe in the local user temp?</p>
