Issue in System.Reflection.MethodBase.Invoke when debugging ASP.NET Core 3 in Visual Studio 2019

问题

I am writing an ASP.NET Core 3 Razor Page app in VS2019. I have started to get a message, "To prevent an unsafe abort when evaluating the function 'System.Reflection.MethodBase.Invoke' all threads were allowed to run..."

Can someone tell what is going on and how to resolve it? Thanks
