I've got a default app generated with dotnet new angular and Microsoft.DotNet.Web.Spa.ProjectTemplates::2.0.0-preview1-final.

When I run the project and then change any files according to the output log recompilation happens immediately. But the browser waits for 5-10 seconds before reloading a page. This only happens under IIS Express debugging, dotnet run is not affected.

Looking at the websocket activity in the browser, a["{\"type\":\"ok\"}"] message comes in without delays.
