When will Blazor support Web Serial Api for use on the client side with WebAssembly? I have a need to communicate with a Com Port from the end users browser. I thought that since I had enabled the permission through chrome://flags/#enable-experimental-web-platform-features that I could use System.IO.Ports and then call SerialPort.GetPortName() to get a list of available Com Ports. When I make the call GetPortName() I get an exception. How can I get this to work with C# code / WebAssembly?
