Browser link crashing with VS 16.3 preview 2 and/or dotnet core 3 preview 8

This was working yesterday (16.3 preview 1) and dotnet core 3 preview 7, even though the app is a 2.2 app.

Start up the web site, all ok.
Attach a browser, all starts off ok.
Then visual studio crashes and closes.

The event viewer shows the following which makes me think it is BrowserLink

Application: devenv.exe
Framework Version: v4.0.30319

The same project in VS 16.2 works ok.

This looks like a bug that has been fixed in visual studio 16.4 preview 2. See https://developercommunity.visualstudio.com/content/problem/756700/browserlink-crashes-visual-studio-in-aspnet-core-3.html for more details
