Fix XDesProc.exe so it doesn't hang everyone's systems.

Just wondering, are you deliberately ignoring this bug, which has been reported by hundreds of developers?

Rest assured, we’re not deliberately ignoring the bug. Far from it, in fact. The issues with XDesProc are tricky, as I’m sure you’d understand. While the reliability is getting better and we’re seeing a decrease in reported issues, we’re still making some large steps to improve it further. Naturally, if you’ve got any details on what you were doing when XDesProc caused issues, we’d love to hear them and make sure that our efforts address the issues. You can report these issues using the “Report a problem” feature on the Help menu in Visual Studio, and also make sure that you’ve configured Visual Studio to send us crash reports (On the Help menu, select Settings under Send Feedback)

In the meantime, I can lay your fears to rest and assure you that we’ve redoubled our efforts to make the XAML designer the best designer anywhere.

    I am using log4cpp. When I run my app, then close it down, I cannot delete my log files because XDesProc is locking them. What gives? This isn't even related to building or opening project files. Then, when I do another Run, sometimes the logger creates another log file because the one is in use

    Using Community 2017. My build fails because a file it's trying to copy over is used by another process (XDesProc). This happens if and only if I have had a certain XAML file open at any point even if I had since closed it.

    Still problem with VS2013 Update 5.
    Cannot compile(link) my program 'cos DLL can't be deleted. Closed VS2013 but still cannot delete my DLL as 'This action can't be completed because the file is still open in XDesProc.exe - Close the file and try again' HOW CAN I CLOSE THE FILE??

    Still a constant hassle with VS2013 Update 4.This is becoming a serious problem for WPF's acceptance among dev's.

    It would be great if we could opt out of the xaml designer entirely and easily. There are some workarounds, but they generally end up with you having to "OK" an error message every time you open a xaml file.

    Completely agree! If it wasn't for intellisense I'd be using notepad++ to edit XAML. The visual designer is worthless for anything that isn't trivial anyway...
