Did I forget anything?
What should I do now?
I have a UWP Xamarin Forms app that is in the Microsoft Store. I've updated this app in the partner center several times without trouble. My last update was 1/31/2020.
Yesterday I submitted another update but it failed with the following message:
This submission failed with error code(s) 1201
In searching I've come across threads like this This submission failed with error code(s) 2003,1201 which point to problems with Microsoft.NETCore.UniversalWindowsPlatform, but I've not changed that in this submission. Here's a listing of the nuget packages that I changed with this new submission:
Microsoft AppCenter 2.1.1 to 2.6.4
Xamarin.Forms 4.2.0.848062 to 4.4.0.991640
I've also added Xamarin.Essentials 1.3.1
How can I go about troubleshooting this to figure out what the problem is?
Update:
I've determined it is not AppCenter nor Xamarin.Essentials.
Updating from Xamarin.Forms 4.2.0.848062 to 4.3.x OR 4.4.x causes the problem.
In addition, I noticed something I didn't see before: There is a 'silent' error when packaging for the store with Xamarin.Forms 4.3/4.4. This error is NOT present with Xamarin.Forms 4.2.x. The error is:
C:\Program Files (x86)\Microsoft Visual Studio\2017\Professional\MSBuild\Microsoft\VisualStudio\v15.0\AppxPackage\Microsoft.AppXPackage.Targets(3385,5): error MSB6006: "mspdbcmf.exe" exited with code 1106.
It seems likely that the above error is related to the submission error.
Update 2:
I found the following post on the mspdbcmf error:
https://developercommunity.visualstudio.com/content/problem/855376/mspdbcmfexe-exited-with-code-1106.html
I used the workaround described and I was able to get rid of the silent build error but my app submission still fails with error 1201.
When i install CORS Nuget package (Microsoft.AspNet.WebApi.Cors), Following error shows (TemporaryGeneratedFile .....),
Error 112 SA1633 : CSharp.Documentation : The file has no header, the
header Xml is invalid, or the header is not located at the top of the

have anybody encountered it before?
Edit:
There is this stylecop enabled in the project.
Looks like a StyleCop issue, see the link for a fix

I hope to build a social network website through monox. I downloaded monoX_5_1_40_5107. When I compiled monox project in visual studio, there are errors of missing RewrittenPath class. I searched the keyword "RewrittenPath" in the entire project, I can't find any definition about it. But when I like to continue and run the last successful build, the website runs well, I can create import the database into local database, and even can create new account info through website.
the compilation erorrs is as below: :
Error 3 The type or namespace name 'RewrittenPath' could not be found (are you missing a using directive or an assembly reference?) Documents\Visual Studio 2013\Projects\WebApplication1\WebApplication1\MonoX\T4Templates\RewrittenPaths.cs 27 13 WebApplication1
The latest version monoX_5_1_40_5150 was just released,and the problem is fixed in this version.So just update project with the latest version.
