VS2012 can't connect to WP8 emulator

Question

I use

• Windows 8 Pro 64 bit
• AMD FX(tm)-4100 Quad-Core (support Hyper-V)
• Visual Studio 2012 update 2
• Latest Windows Phone 8 SDK
• Latest DirectX

My problem: Visual Studio can't connect to emulator. Exactly CAN'T CONNECT, because I can see running emulator from Hyper-V Manager when try to run project.

On picture I present situation:

I have following scenario:

1. Click "Run" on emulator
2. Hyper-V Manager I can connect to emulator and check that it's works, but in VS I see only "The Windows Phone OS is starting..."
3. After 5 minutes emulator turned off by himself.

I already check all popular similar discussion about that problem, but can't make it works.

Note: All works great a week ago.

Answer 1

I ran into the exact same symptoms. For me, the following worked:

1. Shut down the emulator
2. From Hyper-V Manager, open Virtual Switch Manager
3. Select the Windows Phone Emulator Internal Switch
4. Click Remove
5. Click OK

Once I did that, debugging from VS magically worked again. Checking back in Virtual Switch Manager shows it automatically recreated the switch for the emulator. Hope it helps.
