Slow build time - 1m 16s to build sample Blazor app

[adammccrory]

Sample blazor app taking 1m16s to compile via command line... same app on another PC takes ~3 seconds - have uninstalled all previous versions of .Net in comparison and a dotnet build on a simple console app takes <3 seconds

Console app template takes ~3s
WebApi app template takes ~3s
Razor app template takes > 1 Minute
Blazor app template takes > 1 Minute

App created using "dotnet new blazor -o BlazorApp1"

I imagine that you're running into aspnet/Razor#2406 - you can work around this for now by setting <UseRazorBuildServer>false</UseRazorBuildServer>. This will be fixed in an upcoming patch release of the .NET SDK

Yep that fixes the issue - Thanks

Great! For anyone else who sees this, this impacts folks on windows with a space in their username. The underlying issue will be fixed in a patch release of the .NET SDK
