I have one app, I copied the whole folder and proceeded to edit it out, turning it into a new app.
Now, during testing, if I debug the first app (let's call it parent app), and then proceed to debug the second app (child app), the parent app is no longer there. It has been replaced by the child app and vice versa.
Digging deeper into this, I proceed to change out some of the Properties. I changed the Assembly Information to fit it properly, changed the GUID and all.
The only piece of data that stays the same is the Assembly name. The Assembly name is the same for both of the apps because changing it is a bit trickier since I get an debugger error if I do that.
My question is what makes an app unique and how could I achieve to have both the apps installed at the same time ?
Apparently, an app is considered unique based on the
ProductID="{XXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX}" line found in the WPManifest.xml.
This line can't be found in the Properties, and can only be found in the mentioned xml.

Windows 8 has a feature: it can launch an application from the search panel (on the right side of the screen). It works like following:
Developer registers his or her application following this instruction. It is a bit legacy instruction, but the project I participate in uses this way to register its settings.
At user logon Windows creates (if none exists) a special .xml file in C:\User\<UserName>\AppData\Packages\windows.immersivecontrolpanel_cw5n1h2txyewy\LocalState\Indexed\Settings\en-US with content shown below. This file has extension settingscontent-ms
As soon as user clicked on this file, the system launches the specified application (actually explorer calls for it, as I discovered by ProcMon).
Xml file content:
<?xml version="1.0" encoding="UTF-8"?>
<PCSettings>

We can see node with the name HostID. Windows writes specified in code GUID to this node, but it breaks the ability of my application to work. If I try to execute my app through this "shortcut" by clicking on xml file or chosing my app in search panel, the system shows me a message: "Unspecified error".
When I manually change the HostID value to {12B1697E-D3A0-4DBC-B568-CCF64A3F934D}, it starts to wrk fine.
I looked through registry in order to find something about these two GUIDs, but I didn't find anything. Also I looked for the difference between registry values corresponding to my app and to another, but working, app and didn't find any significand differences too.
Also I tried to delete this file and login into the system under ProcMon, I caught some moments: explorer tries to open the file and fails with ERROR_FILE_NOT_FOUND, explorer creates missing file, reads registry and writes something to created file, then it closes the file. But I didn't find anything interesting in between of these messages, that can help me to solve my problem.
I found out that registry key HKEY_CLASSES_ROOT\CLSID\%App GUID%\System.ApplicationName contains exactly the same with DeepLink tag (it was the first error in my app - specified key was empty), but the proble with "wrong" HostID remains.
Does anyone know, what it is and how to make Windows to write the rigth GUID to this tag, or at least some useful info about this tag? I just can't imagine anything else to change, but I think, that I need to change something in corresponding to my app registry keys.
I found the solution: just put app's GUID (the same as in PageID) into DeepLink.
To do this, you need to write this GUID as string value to HKEY_CLASSES_ROOT\CLSID\%App GUID%\System.ApplicationName.
That's the solution. However, I haven't found the meaning of HostID tag :(
I'm creating a cordova app for Windows.
Now when I build this normally (with my own identity of which I have no clue where he gets it from) everything works fine and my app launches with success.
Although when I then associate my app with the Store, and have my actual app name + package name etc filled in for me, I get a blank screen when trying to run my app.
The head and body tags stay empty and no error is thrown in my JavaScript console.
Any idea of why this happens? The problem definitely is that I associate my app with the Store and then something happens which makes my app crash or fail to start.
But why does it do this? And how can I resolve it?
(currently building with VS2017)
edit
Alright, so I figured out that because the package name changed, I had to edit that as well in the manifest. Now My main root component is loaded, but it isn't setting the app root to any page, just a blank screen. (with a menu that can open on swipe).
Alright, so my Microsoft assigned package name was different than my own. This caused the app to look for my own package name instead of the Microsoft one I associated with.
The solution was quite simple, just set your widget-id in your config.xml to the Microsoft assigned package name and rebuild your solution.

iOS 10 / Xcode 8 GM build getting the below, never had it before on Xcode 7. Any ideas?
objc[25161]: Class PLBuildVersion is implemented in both
/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator.sdk/System/Library/PrivateFrameworks/AssetsLibraryServices.framework/AssetsLibraryServices
(0x12049a910) and
/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator.sdk/System/Library/PrivateFrameworks/PhotoLibraryServices.framework/PhotoLibraryServices
(0x1202c4210). One of the two will be used. Which one is undefined.
(NOTE: Only seems to happen in simulator, does not appear on real device).
Main Idea
Main idea is simple:
If your app (or dependencies, such as Pods) uses framework, that uses explicit (or implicit) PhotoLibraryServices.framework or AssetsLibraryServices.framework as dependency, Xcode warns you (even if you are using only one of them). It might be Photos/PhotosUI.framework or AssetsLibrary.framework, or another (I don't have full list of dependencies, but it is possible).
What is the problem?
Class with name PLBuildVersion is defined in both PhotoLibraryServices.framework and AssetsLibraryServices.framework. Class name is unique in Objective-C (you can't define 2 classes with same name), so it is undefined which one will be used in runtime.
However, I think that it will not be a problem, because both classes have same methods and fields (checked this with disassembler) and I guess that both were compiled from the same source.
Radar is already sent.
As per answer from Apple employee on Apple's Developer Forum:
You don't control either of the class sources listed, so there isn't anything you can or should do – aside from Reporting a Bug.
I was unable to find a way to get rid of the warning, but if you want to prevent the app from crashing, you need to provide a description for why you are accessing the camera, photo library, etc. This is new in iOS10.
Input the following into your Info.plist file.
Photo
Key: Privacy - Photo Library Usage Description
Value: $(PRODUCT_NAME) photo use
Camera
Key: Privacy - Camera Usage Description
Value: $(PRODUCT_NAME) camera use

I find you can get this error merely by using a UIWebView. My solution was to replace my use of UIWebView with WKWebView.
I had this after adding Answers on Fabric to my project.
Deleting derived data did the trick for me. (shift alt command k in XCode)
Edit a year later:
After deleting derived data, always exit XCode and start it again.
In unrelated cases I have the impression that deleting derived data does not clear XCode’s in memory caches of the derived data.
Resetting the iOS simulator fixed this for me. Simulator -> Reset Content And Settings.
In my case this warning started to appear after opening a second xcode project and running the second app on the simulator. After changing back to the first app, the warning started to appear. I just quit the Simulator and Xcode and reopened my project. The warning disappeared after that. If that doesn't solve it, proceed with the other answers. Xcode can be really picky sometimes.
Long story short, I made an app, and now that it is done, I thought of a better name.
When I change the product name, it asks if I want to let it automatically change the name everywhere else. Unfortunately, after doing so, I deploy the app, but it still shows the old name on my device. I have tried many things to fix it, but no luck.
Any ideas?
Did you try deleting the app from the device and cleaning the targets on the project before deploying to the device again.
I guess we can add this question to the list. Basically It's been taking me twice the time to try something out because everytime I try to debug my app I have to wait about a minute to lauch the app. There are 3 files in order that it complains about.
Resources file (.g)
Program Debug Database
DLL (.dll)
I tried removing the first two, but then it complains about the DLL file. Strangely enough I have never encountered this and I've been using the the WP7 emulator in VS2010 for about a year. Any ideas? Is there possibly a setting or cache that can be deactivated?
Basically when you add images to your project, by default they are added as a resource. By doing this everytime you try to build the project the images are saved in the dll file thus the long wait time. I set 95% of my images to content and have not had the issue since.
