Hi Dave,

Can you please clarify the scenario?
Is this issue present building UWP projects caused by having Xamarin current stable installed on the same environment? or are you reporting an issue on Xamarin.Forms UWP support?

As per description, it seems like the bug is already fixed with `cycle8` builds. Please confirm.

Thanks!
Comment 2 Dave Voyles 2016-08-24 18:36:27 UTC
I thought the bug was fixed (it managed to fix it on my Surface Book), but did not fix the issue on my desktop.

On my desktop, I just switched back to the latest stable build, 4.1.2.18, and still receive this error.

Scenario 1 :
Open an existing Xamarin.Forms shared project.
Select UWP as the startup project
Select x86
Deploy to local device

ERROR:
Could not locate C:\Users\Desktop\Desktop\8.24.16\Hendrick%20Mobile\ShopInsightsMobile\ShopInsightsMobile.UWP\packages.config.  Ensure that this project has Microsoft.Bcl.Build installed and packages.config is located next to the project file.	ShopInsightsMobile.UWP
Comment 3 Jose Gallardo 2016-08-29 13:41:55 UTC
Moving the report to Product Forms, for visibility from the Xamarin.Forms team, as this looks like an issue with Xamarin.Forms UWP support.

Thanks
Comment 4 Dave Voyles 2016-08-29 14:13:16 UTC
Thanks.

Oddly enough, the Stable branch works fine on my Surface Book, but not on my desktop.

I compared my Desktop w/ my Visual Studio diagnostics (versions of VS, Xamarin, etc) with a co-worker, and they are identical, but he does not have that problem.

On the Surface Book, it will still throw an error about packages.config, but it still builds the project. Not sure.
Comment 5 Paul DiPietro [MSFT] 2016-08-30 16:42:09 UTC
What version of Forms are you trying to use? I'm able to build and run a UWP project on the latest prerelease, and have the stable branch installed on VS.
Comment 6 Dave Voyles 2016-08-31 11:37:49 UTC
I am in Seattle for the rest of the week, and this work was done on my desktop, in Philadelphia.

When I return on Monday I'll follow up in this thread with the version information and my DXdiag.
Comment 7 Samantha Houts [MSFT] 2016-09-23 17:36:47 UTC
@Dave Voyles,

Were you able to resolve this issue on your Surface Book? 

Warm regards,
Xamarin Forms Team
Comment 8 Dave Voyles 2016-09-23 18:01:33 UTC
Hello,

I just tried building a new project on my desktop. It works fine.

Tried the same steps on my Surface Book, and ran into these errors:

Figured I had to restart VS, so I did, and it only came back with:

Error	CS0103	The name 'InitializeComponent' does not exist in the current context	XamTest.UWP
Comment 9 Paul DiPietro [MSFT] 2017-02-21 17:28:04 UTC
Are you still experiencing issues with this using the latest stable versions of everything?
Comment 10 Dave Voyles 2017-02-21 21:25:07 UTC
It seems to work again!
Comment 11 Paul DiPietro [MSFT] 2017-02-21 21:36:18 UTC
Glad to hear it. Going to set this to resolved, then.
