Extremely slow build time with Visual Studio 2015 U3 + .NET Core

Question

I hope this is the appropriate place for this question. I've tried other various avenues and turned up no results... please let me know if this belongs on another stackexchange site.

I am using Visual Studio 2015 Update 3 and .NET Core - specifically ASP.NET Core, to build a large website. It runs fine, and if I compile from the command line using dotnet build, everything is fast and efficient.

But if I try to do a Build within Visual Studio, it takes quite a while. Several minutes, in fact. I cannot quite figure out why either.

The solution has 13 projects, and none of them are very big except a single *.Web project. I suspected that the slowdown was because of it trying to process all the *.js, *.ts, *.scss, *.css and *.html files - but even if I remove that project from the solution, I still get the poor performance.

This occurs even on a fresh install of Windows 10 x64 with Visual Studio 2015 Professional /w Update 3.

I've posted a detailed log of my entire build (warning, it's an extremely large pastebin) for people to look at, and see if they can help me identify where the problem is. I do not know enough about the build process to make much sense of this...

The pastebin is very slow for me. If someone is interested in helping and cannot get it to load, I've also created a dropbox log for you to download. If further information would be useful, please let me know. I'm pretty eager to get this fixed, it's driving me nuts.

I mean that the log is very big, so it locks up my browser from time to time — Ciel, Aug 25 '16 at 11:29
The log seems to load fine on FireFox and Edge, though. It gives me a lot of trouble in Chrome. — Ciel, Aug 25 '16 at 12:09
if you use .net core 1.1 take a look at this issue https://github.com/aspnet/Home/issues/1829 — Søren, Mar 05 '17 at 07:07

Can you add a sentence to explain WHY this solves the problem? Thanks. – fixer1234 Jan 09 '17 at 03:37
