UWP: AutoSuggestBox crashs in RS1 mobile devices

I'm coding a UWP app. The problem is that AutoSuggestBox works everywhere, but crashes on RS1(Build 14393) phones and mobile emulators and I donno what's wrong.
This is the code.
<AutoSuggestBox Margin="2" x:Name="txtAutoComplete" PlaceholderText="Search" QueryIcon="Find"
TextChanged="AutoSuggestBox_TextChanged"
QuerySubmitted="AutoSuggestBox_QuerySubmitted"
SuggestionChosen="AutoSuggestBox_SuggestionChosen" Style="{StaticResource Box1}"/>
Note: I removed my styles and events. But no result :(
EDIT:
The error I get:
NOTE: It worx just fine in PC (any build) and mobile (RS2).And not tested in Th2 mobile phones.
Error: The text associated with this error code could not be found.\r\n\r\nCannot find a Resource with the Name/Key AutoSuggestBoxIconFontSize [Line: 2746 Position: 284]

This is a known issue I blogged about a few months ago.
Since you're able to develop for RS2, I assume you have the SDK for it installed as well. When creating a style, it uses the target version (probably RS2) as the default template to start from, bringing along all new properties that are not available in older releases.
If you want to be able to run on 14393, change the target version to 14393 and recreate your style.
You can also try to use the 14393 style and start from there on to customize (I haven't tried that approach myself though). You can find it in C:\Program Files (x86)\Windows Kits\10\DesignTime\CommonConfiguration\Neutral\UAP\10.0.14393.0\Generic\generic.xaml starting at line 14174.

Windows 10 System.Exception: Install failed. Please contact your software vendor

I'd like to create 2 apps from the same project(VS solution), both of them has the same functional with small differences. So I just made 2 copies of my solution and I changed solution name, namespace and asigned app to different Microsoft Store app. When I try to instal secnod app on phone I get:
2>caught exception: System.Exception: Install failed. Please contact your software vendor. (Exception from HRESULT: 0x80073CF9)

As is mentioned in other questions, if I uninstall one of them, the second is installing but I'd like to made some changes to install both of them. Have to mention that on PC I can install both apps from Visual Studio with no errors.
I am using:
Windows 10 Pro
Visual Studio Version 14.0.24720.00 Update1
Mobile Emulator 10.0.10240.0
Any advices are appreciated.
P.s. In android we have gradle flavors that helps us to build different apps from the same Android Studio project, maybe there is something similar in Visual Studio?

The purpose of reserving multiple names for an App is that the name has meaning for different languages. E.g. an English speaking person would understand "My Great App" and a German speaking e.g. "Meine tolle App". When you assign multiple names to the same App which is identified by it's ID you do not have two Apps but just one with multiple names. That is why you're getting the error.
You could try to change these IDs manually but the easiest, fastest and safest way would be to just let Visual Studio do the work by creating a new project and copy/paste/include your files.
Anyway if your intention is to create a "Free" and a "Pro" version you should consider doing it the recommended way and use in App purchases or create a trial version.

In the package.appxmanifest file, in the Package tab change the Package Name value. Notice how changing this will also change the Package Family Name as well.
Lastly, change the Display Name from the Application tab so you can differentiate the apps when ruuning.

MdilXapCompile.exe failed with error code 2001

Release/Debug ARM deploy to device isn't possible. But the build succeeds.
I get following exception:
Severity Code Description Project File Line Error Error : DEP6810 :
MdilXapCompile.exe failed with error code 2001. See log file
'C:\Users..\obj\ARM\Debug\MDIL\MDILXapCompileLog.txt' for more
details.
MDILXapCompileLog.txt:
CrossGen failed Error processing assembly
C:\Users...\obj\ARM\Debug\MSIL\Microsoft.Band.dll Raw error code:

Google lead me to following solution:
Close Visual Studio
Navigate to YourSolution/Packages/
Delete everything except packages.config
Reopen the solution in Visual Studio
Right click on solution and select "Manage Nuget Packages"
Click the "Restore" button that appears at the top of the dialog
window
Doesn't work for me. Any other suggestions?
Thanks in advance

If WP 8.1, uninstall the app and run deploy, it worked for me.

When you deploy the Device make sure to select Debug instead of Release. If you set to Release the app will not be deployed and the above error will occur.
Select Debug and set the deployment destination as Device. Unlock the phone and run. It will work.

Upgrading wp8 to wp8.1 silverlight, debugger cannot be launched

I have now had an error with VS2013 and WP8.1 silverlight for a couple of days.
I get a couple of different errors, ..Ensure unlocked screen.., AgHost.exe could not be launched, port is in use by another program and ensure the device is unlocked.
These errors came suddenly after I retarged the solution. I have no compiling errors.
Solution Attempts
Restart PC
Restart program
unregister and reregister the phone
reinstall Update 3
reinstall VS2013
Windows Phone 8 Application crash once its launched AgHost.exe' has exited with code -532265403
Install VS2015 with no luck.
reinstall VS2013 Update 4
Nothing worked. The error is also the same for emulator as well as different devices. I can however get the release mode installed. Break points can be used when using release mode, but I have to Clean, Rebuild and then deploy for every time I want to deploy the application. Further the deploy time has gone up exponentially. Before upgrading I used a maximum of 10 seconds. Now it is above a minute in wait time. :/
Anyone has a solution for this ?
Extra
If I run the solution before upgrade on device or Emulator It spins up with debugger. If then go to the updated WP81, I get a popup with info Something is taking longer then normal and then it crashes with ..Ensure unlocked screen.. :/
Could it be an issue with the differen SDKS?
During a repair of all the SDKs, I found an issue with the event log, which I cleared based on The Event Log File is full
Still no success.
Extra
I cannot spin up the emulator from VS2013, when using the WP8.1 solution, but the wp8.0 solution in the same VS works :S
I found an error in a log file, from:

Anybody knows what to do with this? The error is coming when I repair Windows Phone SDK 8.0

There was a post-VS2013 update for the Windows Phone 8.1 SDK, some odds that you don't have it installed since you did not need it before. The download location is here.
Getting error messages like "port is in use" when there's no obvious reason why it should be in use and seeing excessive download times is also a very strong selector for your installed anti-malware product getting in the way. No specific advice on how to configure it when we don't know what it might be. You definitely first want to try to temporarily disable it so you can identify it as the source of the problem.

I have no Idea of what is the issue, but creating a new solution and importing the existing projects into a new solution has solved all the issues regarding emulator and debugger an AgHost.
Seems like the upgrade function integrated in the solution did not work properly.

Windows store app fails AppContainerCheck

I'm getting the below error when I try to run the app certification test on my windows 8.1 app. I've looked around for a while and can't seem to find any solutions for this. The app is written in C#/xaml which I wasn't aware even had a linker.
I'm hoping that someone can guide me in the right direction on how I should start to investigate an error like this as web searches have thus far failed me
Binary analyzer
•Error Found: The binary analyzer test detected the following errors:
◦File [MyTabletApplication.exe] has failed the AppContainerCheck check.
•Impact if not fixed: If the app doesn’t use the available Windows protections, it can increase the vulnerability of the customer's computer to malware.
•How to fix: Apply the required linker options - SAFESEH, DYNAMICBASE, NXCOMPAT, and APPCONTAINER - when you link the app. See links below for more information:

If you are using Visual Studio 2015 and this is a new solution/project make sure the 'Compile with .NET Native tool chain' check box is cleared in the startup project properties in the Release configuration.
