Windows phone app development in WP8 SDK - windows-phone-7

I am a Windows Phone 7 app developer. Now I am using Visual Studio 2010 and WP7 SDK and Windows 7 OS. But I am planning to install Windows 8 OS and Windows Phone 8 SDK and Visual Studio 2012 in my system. If I do so, can I develop windows phone 7.0 and windows phone 7.1 apps with WP8 SDK and Visual studio 2012 ?
And also I developed some apps in WP7, So if any bug fix needs, Can I do it using WP8 SDK ?

You can develop 7.1 Apps and 8.0 apps but NOT 7.0 apps with the 8.0 SDK... Although I think devices with system version prior to 7.1 don't have access to the store so you don't need to maintain a 7.0 version of your app....
Of course any wp7.1 project can be opened with the new SDK 8.0 without problems.

Yes, Windows 8 and visual studio 2012 support WP7 development. There's a WP7 emulator and you can also connect and use your own WP7 test device.

Upgrade from Windows Phone 8.0 Development to Windows Phone 8.1 Development

I am Developing Apps on "Microsoft Visual Studio Express 2012 For Windows Phone". I develop Windows Phone 8.0 Apps.
Now I need to develop Windows Phone 8.1 Apps free. Which Visual Studio to use for this purpose.? and What about windows Phone 8.1 Emulator.
If possible share both download links.
You Should use Visual Studio 2013. here is a download link for Express 2013 for Windows
that can be used for windows and windows phone as well as Universal Apps. for windows phone 8.1 emulators, you can download them from here Windows Phone 8.1 Emulators
To develop Windows Phone 8.1 App, You should use Visual Studio 2013.
And here is the download link: Visual Studio Downloads
On the Dev Center of Microsoft you can find all information, samples and tools you need to develop Windows and Windows Phone apps.
Info from the site regarding to WP development:
Windows Phone 8.1 development tools:
The Windows Phone 8.1 development tools are installed with Visual Studio Express 2013 for Windows with Update 2 and Visual Studio 2013 Update 2.
Windows Phone 8.1 Emulators:
This package requires Visual Studio 2013 with Update 2 or later, Windows 8.1 (x64) Professional edition or higher, and a processor that supports Client Hyper-V and Second Level Address Translation (SLAT).
Here are several links to useful parts of the site:
Downloads (scroll to Windows Phone section)
SDK
Note: with these tools, you can still develop Windows Phone 8.0 apps as well.
You have to use Option in visual studio 2013 express from here.
Edit:
After Installation open your windows phone 8.0 project in visual studio 2013 fallow the process described here. As same as windows phone 8 emulators will comes under windows phone Sdk
Check this link about Documention.
Note:
I suggest you to back up of your windows phone 8.0 project to separate Folder to continue the development of windows phone 8.0.
Why:
You cannot downgrade a upgraded app with version 8.1 to version 8 or 7.1.
All the Best.

Testing windows phone 7.1 app on windows phone 8

Now from what I see it is possible to test my app on windows phone 8, however would I need to import the project to vs2012 and would i need to download the sdk8.0 or can i use the sdk that i have (7.1, vs 2010)
You need the Windows Phone SDK 8.0 to deploy your app to a Windows Phone 8 device. And the SDK 8.0 only works with Visual Studio 2012 (Pro, Express, ...). Here's more reading on deploying and testing 7.1 apps for version 8: How to deploy and run a Windows Phone app (About deploying and running apps on a Windows Phone device).
You need to add the new sdk and follow all the explanation of this link :

Develop Windows Phone on Visual Studio 2013 On Windows 7

I own a Windows 7 (Home Premium) and Visual Studio 2013.
As a part of a project for Uni, we are required to write an application for Windows Phone, basically - they require for Windows Phone 8, but I even think that Windows Phone 7 will do.
My question is this:
Other than installing Visual Studio 2012 + WindowsPhone7 SDK or Installing Windows 8 and Visual Studio 2013, or using a VM with one of these -
Is there a way to develop for Windows Phone 7 or 8, under Windows 7???
I don't currently have a physical windows phone and will have to use an emulator for that.
Windows phone 8/windows store apps under windows 7 OS is not possible, you need a windows 8 OS
You can develop for windows phone 8/windows phone 7 (7.1) with windows 8 OS
Windows 7 OS obviously supports windows phone 7 development
See this post
there are other hardware requirements such as Hyper V for windows phone 8 emulator support in windows 8 OS
Hy,
You can keep both versions of VisualStudio on the same machine, but keep in mind that if you want to develop applications for Windows8 or WindowsPhone8 on Windows7 operating systems this is not possible because you miss the new framework WindowsRuntime, so I advise you to keep windows 8 as operating system, VisualStudio 21012 + sdk for WindowsPhone7 and VisualStudio 2013 SDK for windowsphone 8 and developments already built for Windows Phone8.
You cannot develop a WP8 app on Windows 7. You can develop a WP7 app on Windows 7 using VS 2010 plus the WP7 SDKs - WP 7.1 SDK, WP7.1.1 SDK, WP7.8 SDK - http://blogs.windows.com/windows_phone/b/wpdev/archive/2013/01/22/now-available-windows-phone-sdk-update-for-7-8.aspx.

How to run windows phone app from visual studio?

I am developing phone gap application for windows phone.I am using visual studio 2010 & windows phone sdk 7.0.
How to run my application on windows phone 8?Or I have to run it on windows phone 7.
I am unable to connect my windows phone os 8 to visual studio.
Please help
If you have a windows phone 8 device which you want to use for app debugging purpose, you NEED the Windows Phone SDK 8.0 installed, which needs at least a 64-bit Windows 8 Pro or better.
If i haven't forgotten something, then Phonegap has 2 project templates - 1 for WP7 and 1 for WP8. Which allows to think that WP7 project won't run on WP8.

Develop for Windows Phone 7 (or 7.1) using Visual Studio 2012 (RTM,Premium)

Is it possible to get the WindowsPhone 7.1.1 sdk to work with Visual Studio 2012?
Edit: As stated in the title of my question: I wanted to know whether its possible to develop windows phone 7.1.1 apps using Visual Studio 2012.
I already tried installing the SDK and the hotfix but I still can't open Windows Phone 7.1 projects with VS2012. Hence, my question: Am I missing something obvious or is it simply not possbile?
There we go :) --> Windows Phone SDK 8.0
I have both Visual studio 2012 RTM (for Windows 8 store application development) and Windows phone 7.1.1 SDK in my Windows 8 Release Preview and they are working fine.
And like you, I am also waiting for the Windows Phone 8 SDK.(btw, there is no windows phone 7.8 sdk)
UPDATE: This Windows Phone 8.0 SDK link states that "you can install Windows Phone SDK 7.1 (and the WPSDK 7.1.1 Update) and continue to build apps and games that target Windows Phone 7.5. The existing Windows Phone SDK installs side by side with Visual Studio 2012, and you can feel confident that the code you write today will work on Windows Phone 8 devices."
