Safe handle has been closed error with XAML designer

Question

Since last Visual Studio update every time I start debugging after I return all xaml designer crashes with the Safe handle has been closed error... I Have to restart the IDE every time wasting 5 min in the process... Can't find a proper answer nowhere... The link Click here to reload the designer doesn't work either...

Answer 1

Hi,

For instance the XAML designer crash, how about WPF designer and is it only affect Windows Store App? Please try to create a WPF project to test.

And make sure you can  get latest update and then restart the machine.

“Safe handle has been closed error and I Have to restart the IDE every time wasting 5 min in the process”

looks some other process lock the resource, you can  close the possible process one by one and then open the VS to test.

Best Wishes

I did the latest .Net update and it never happened again... ?

Corrupted files maybe... But the error source always came from the .Net cache...

Answer 3

Hi,

If the error occurs in all of apps not only one app, lt seems your VS may be corrupt. Please try to repair the VS. If the error occurs after you repair the VS, Please share some logs file to me:

Try to use http://aka.ms/vscollect  to gather the installation logs. You will find vslogs.cab from %temp% folder. Please upload the file to  https://onedrive.live.com/   and share the link here.

Best Wishes!

Answer 4

I was working on Windows Server 2012 R2 for development of Windows Store apps using the Administrator account (I know very bad)... So had to do a little bit of tweaking. Anyway, the fact is why Administrator account cannot access Windows Store apps is quite bothering... Installed a new pc with Windows 8.1 still got to restart VS as admin some times depending on the code (Registry access require admin to write...), but still you can't work on a remote shared folder on Windows Store apps (cannot register bla bla bla...) but there is no DFS in Windows 8.1 so I have to write scripts to copy the code to the DFS Shared Folder with replication... It's annoying to have to always use workaround just to get basic stuff that used to be quick and simple before !
