I've downloaded the Windows Phone 8.1 SDK Update and I'm attempting to make a Windows Phone 8.1 project. I've updated visual studio with the latest patches but the only template options I have for 8.1 is the standard Windows Store apps as seen in the screenshot below:
Windows Store
Any idea how I can get "Windows Phone" to appear with the appropriate OS target?
I think you didn't install everything. Because i've got actually another screenshot. Following this link you must install Visual Studio 2013 Update 2 - everything needed for WP8.1 is there. Also if you wish to develop Windows Store apps (universal or something) you should install Windows 8.1 SDK from here
Look a bit bown in the list on your screenshot. On the same level the 2nd last option is Windows Phone. That should be it.

I am creating a Xamarin project, and I made it working with Android and iOS, but I can't figure out how to start the Windows Phone 8.1 emulator.
Windows Phone 8.1 is created as a project just like the other platforms.
I am running Visual Studio 2015 Community and Xamarin Business.
EDIT
I made it running by setting it as startup project, but are there others way by e.g. changing the project (where you choose if it is debug or release)?
I also want to know, how I can create the application to Windows store
To create app package go to
Project->Store->Create App Package - It will open wizard for creating app package that You are able to send to store (reference: https://msdn.microsoft.com/en-us/library/hh975357.aspx)
As for the other ways:
In Visual Studio 2015 You can choose in taskbar: debug/release, CPU architecture, startup project and where to deploy an app - eg. emulator or device
The app is live on the Windows Store and has a 8.0 version. If I re-target to Windows Phone 8.1 and publish with new features, will it be available for Windows Phone 8.0 users?
Most of our users are still on 8.0.
The user (OS/Store) downloads the most suitable package of the app. If user has WP8.1 and your app has a 8.1 package, then this will be installed, otherwise 8.0 app package will be downloaded.
From what you have written, you already have a working WP8.0 version of the app, now if you want to add some new features from 8.1 then, once you retarget the app, you have to add new package to your app when you are updating it. Do not replace the old working 8.0 package. Once you have added new package and it has passed certification, all users that have 8.0 version of your app and 8.1 OS version, will be prompted that there is an update available.
What is important:
you can retarget to both 8.1 Silverlight and Runtime (of course the second option needs some more changes and some things to be rewritten),
IsolatedStorage is preserved,
when you retarget to Runtime, you will have to parse IsoalatedStorageSettings from file in LocalStorage.
I've done similar thing with WP8.0 -> WP8.1 Runtime, I also recommend to test it on beta app, so you will be sure how it works.
If you re-target the app to Windows Phone 8.1, it'll be available to only Windows Phone 8.1 users. If you submit such an app to Store, it'll be displayed only in devices running Windows Phone 8.1.
However, you can submit two packages for same app in Windows Phone Store. So while submitting an update for your app, instead of replacing the existing Windows Phone 8.0 package, you can add another package for the Windows Phone 8.1 version which will have new features. The Windows Phone Store will ensure that it shows the correct XAP to correct OS version. This way, Windows Phone 8.1 users will be able take advantage of the new features, while Windows Phone 8.0 users will still be able to access the old app.
Going forward, if you want to support both OS versions, I'll suggest to keep a copy of Windows Phone 8.0 project before re-targeting to Windows Phone 8.1.
Yes, if you just re-target the project! But make sure you aren't using native WP 8.1 features, as they wouldn't work on WP8.
We are evaluating Xamarin Forms for our next project to develop the same application for the three major platforms: Android, iOS and Windows Phone.
As we mostly work with WP and Windows apps within the company, we have a well working base setup for work environment. It consists of a Windows 8.1 Pro/Enterprise install, Visual Studio 2013 Update 4 with both WP 8.0 and 8.1 emulators and targets, and all the rest of the packages (e.g. Office Development packages, etc.).
So I grabbed such a laptop, and installed Xamarin on it, using the official download URL on their site. It installed fine, but when I tried to create a new Forms project, it only created the Android part of it, no WP or iOS projects were created.
After checking the settings and all, it turns out that Xamarin Studio won't load the iOS and WP parts which would make it possible to create the projects.
How could I make it see those extensions?
You will need to download the Windows phone SDK update and that will create Windows phone project for you
2008: We don't allow the capability you've specified: ID_CAP_RINGTONE_ADD
I'm submitting a windows phone app (WP8 version) that uses SaveRingtoneTask, and in its WMAppManifest.xml I've specified ID_CAP_RINGTONE_ADD capability, however the error message above still showing
There's WP7.1 version of this app, which I add the assembly reference to this WP8 version, and the SaveRingtoneTask is code is stored in that assembly, does this affect the error above ?
AppPlatformVersion in WMAppManifest.xml already set to "8.0"
Are you creating a Windows Phone 8 app? ID_CAP_RINGTONE_ADD is only available for Windows Phone 8 version.
From this link
In case you haven't you should upgrade the app to Windows Phone 8 by right-clicking the Windows Phone 7.1 project in Visual Studio 2012 and selecting Upgrade to Windows Phone 8. You’ll receive a prompt that cautions you that this upgrade can’t be undone and doesn’t update any referenced projects. You’ll want to make sure that your app is backed up before proceeding. You can also upgrade to Windows Phone 8 by selecting Project Properties, clicking on the Application page, selecting Windows Phone OS 8 from the dropdown list and saving your changes.
I recommend backing up your project before trying this because the changes are not reversible.
Thanks and hope this helps you.
How can I downgrade the target of my project from 8.0 to 7.1?
I tries to set it from project>settings>"Target Windows Phone OS Version" , but in dropdown list there is only one line: "Windows Phone OS 8.0".
Thank you.
That is probably not possible. One thing you can try, set up windows phone 7.0 sdk and try to port your app there from scratch.Yes, i think that's the only way, so create a new project under wp 7.0 and import all of your files there.
SO also tells about it, some suggestions for you that may help:
