We have a Xamarin.Forms app that also supports Windows 8/8.1 as a platform. Xamarin.Forms has support for WinRT and that's how it can be deployed to Windows 8/8.1.
We are using TeeCharts for Xamarin.Forms however, it doesn't seem to support WinRT as a platform. Is there a way to use TeeCharts for Xamarin.Forms with Windows 8/8.1?
I'm afraid TeeChart for Xamarin.Forms doesn't support WinRT (Windows 8/8.1).
However, TeeChart.Store.dll should be able to target this environment without problems. Please, contact "info at steema dot com" - referencing this post - for further instructions about how to get it.

The code works fine on Windows 10,
but I'm getting TargetInvocationException in Windows 8.1 when using uwp bluetooth APIs in my .NET 5 winforms app
inner exception is
Class not registered (0x80040154 (REGDB_E_CLASSNOTREG))
code:
private BluetoothLEAdvertisementWatcher BTWatch = new BluetoothLEAdvertisementWatcher();
in my project I have added reference to "UwpDesktop-Updated" package & windows SDK 10.0.17763.132 is installed on my Windows 8.1 machine.
Let me know how to fix this issue occurring on windows 8.1
TargetInvocationException when using uwp bluetooth APIs in .NET 5 winforms app
I'm afraid you can't run it in Windows 8.1 system, please refer BluetoothLEAdvertisementWatcher document, the support lowest version is Build 10240, and it will not work in Windows 8.1 system.
In my windows phone 8.1 project I am using MediaCapture Api for capturing photo's, but I experienced issue on the devices that comes with 8.0 and later upgarded to 8.1,
The problem is that on such devices camera capture fails after taking 10-15 images and it's just saves green screen instead of original image.
So what I thought is to create 8.0 class library and use CameraCaptureTask of 8.0.
Will that work? If so than Is it recommended way to do so?
Guessing that your 8.1 project is 8.1 XAML not 8.1 Silverlight the answer is no. The camera API really sucks in 8.1 XAML, if it is a core functionality of your app, just go with 8.1 Silverlight.
I'm trying to integrate AdMediator into an Windows Phone 8.1 XAML project. I installed the AdMediator extension and when i access the Ad Networks it only shows Microsoft Advertising, AdDulex,Smaato. Does this mean Admob does not work inside AdMediator, or it needs to be installed manually.
Admob only works on Windows Phone 8.1 Silverlight apps. At the moment, there's no SDK for XAML based apps. See this
To further clarify the title.
I don't mean HTML5 hybrid apps or apps that have been developed for windows 8/ windows phone 8 and run on windows 8.1/ windows phone 8.1
I would like to know if IBM MobileFirst supports native apps written for windows 8.1 and/or windows phone 8.1 .
For example a universal app.
From what I have read and the tutorials I've seen there is no way to generate dlls for windows 8.1 and windows phone 8.1. Am I missing something?
Have you taken a look at the IBM MobileFirst Platform Developer Center or the IBM MobileFirst Platform Knowledge Center? you'll find your answers there...
Windows Phone 8 - There are tutorials for Native Windows Phone 8.x development (more to come in the future).
https://developer.ibm.com/mobilefirstplatform/documentation/getting-started-native-wp8-development-6-3/
http://www-01.ibm.com/support/knowledgecenter/SSZH4A_6.2.0/com.ibm.worklight.dev.doc/dev/c_developing_native_apps_wp8.html
Windows 8 - Native Windows 8 support is also available (but not yet mentioned in the dev center)

#corus I was able to reproduce your problem consistently! What fixed was the changing the build action of the wlclient.properties file to Content.
Go to solution explorer
Right click on wlclient.properties and select "Properties"
Set the "Build action" property to "Content" (this is missing in the knowledge center)
Also set the "Copy to output directory" to "always"
This should fix the crash issue.
#corcus Part 1 - Currently upto IBM MF 6.3 - there is no formal support in the product UI but we have been qualifying Visual Studio 2013 in the meanwhile (https://www.ibm.com/developerworks/community/blogs/worklightsmobileplayground/entry/ibm_worklight_and_microsoft_visual_studio_2013?lang=en)
Part 2 - our current WindowsPhone8 environment is Silverlight based. What you can try doing is Create a native app with Windows8 environment (this will create a C# app). Open it in VS2013 and then add a Windows Phone 8.1 project to it. Then add the DLL references to the phone project and copy the assets to the Phone Project (or Shared Project) and try running on the Win 8.1 phone. This should work (I have tried Hybrid and it works, but not native - hence not saying conclusively)
I have updated my code to WP 8.1 and wanted to organise it better by using Class Libraries.
The doubt comes when I find there are 2 Class library project templates for Windows Phone:
Class Library (Windows Phone)
Class Library (Windows Phone
Silverlight)
If i select template 1, i see the assemblies referenced by default are .NET for Windows Store Apps and Windows Phone 8.1
If i select template 2, i got asked the target version of the Windows Phone OS (8.0 or 8.1) and the assemblies references by default are .NET for Windows Phone and Windows Phone.
Do you know the differences between them?
I have looked into the matter and seems it depends if you want to load the .NET runtime namespaces or not, am i correct? Are there any more differences?
The class library type will depend on whether your main app will be a Windows Phone 8.1 Silverlight app, or Windows Phone 8.1 XAML app.
The advantage of WP8.1 XAML app is that it is converged with Windows 8.1 - you can even create an Universal App that shares almost all code and xaml between the Win8 and WP8.1 apps.
The advantage of WP8.1 Silverlight app is that it is more closer to the old WP8.0 app - less changes are required, and also it has access to some APIs not available to WP8.1 XAML apps.
