copied!<p>I think I may finally at least know the cause, though not the reason why. When the problem started occurring again, I noticed a ton of "conhost.exe" processes orphaned. I would close Visual Studio and they would remain open. Ending task on each of them has finally, reliably solved the problem. [hopefully]</p> <p>(Just note, conhost.exe isn't a Visual Studio process though Visual Studio uses it. Thus, other users out there may have other applications out there that run conhost.exe. I know my machine doesn't which is why I can safely end task all of them but YMMV.)</p> <p>As to why this happens? It seems to occur when I open more than one project at once, which I tend to do often, even though I only build and debug one of them at any time.</p> <hr> <p>Edit #1 - This isn't a "silver bullet" unfortunately. It doesn't always work for me. Typically, when things get slow, I just close all of my Visual Studio sessions, then go into the task manager and end any instance of it, conhost.exe, iisexpress.exe Microsoft.VisualStudio.Web.Host.exe and MSBuild.exe I can find.</p> <p>Typically, after that, when I restart my project it'll then load quickly. But not always.</p> <p>Really I think the best course of action is probably to not build & debug code off a redirected folder/network share.</p> <hr> <p>Edit #2 - Two years later, and this is <em>still</em> an issue for me in Visual Studio Community 2013, but I did seem to at least find the culprit task: <strong>Explorer.exe</strong>. Yeah, who knew. The moment I end that task, bam, page loads in a single second.</p> <p>If I have a Windows Explorer file browser open to my redirected network drive (which is often since that's where my code is), this problem seems to occur. Closing the window isn't enough, I have to kill the whole Explorer.exe task. I could only guess what it's doing...going nuts with file handles?</p> <p>I can usually use the task manager to start up a new explorer.exe task (I can only take so much alt-tabbing), and Visual Studio will continue to load nice and quick. But if I so much as open Windows Explorer again, it almost always goes back to super-slow-mo.</p> <p>So, if you've got a redirected network share, give it a shot. It sure beats working locally.</p>
