I would like to know how to attach windbg to a process running in windows phone 8.1. Googling didn't help. Can anybody help me? Thanks
To Connect WinDbg to an existing process on the phone
1. In TShell, enter this command:
debug-device –debugger WinDbgPath
where WinDbgPath is the path to WinDbg on the host computer.
2. Example:
debug-device –debugger “C:\Program Files (x86)\Windows Kits\8.1\Debuggers\x86\WinDbg.exe”
3. In WinDbg, on the File menu, choose Attach to Process. Select one of the listed processes, and click OK.
For more Refrence Use debug-device in TShell to attach a debugger to a process
You can't use windbg to attach to a process running on a WP8.1 device or emulator (which is really a virtual machine and so for all intents and purposes is a different machine) using the public tools. Microsoft may have internal tools for this but IF they do they're not available.
You haven't said what you're trying to achieve but you'll probably need to use the Performance and Diagnostics tools (via debug menu) to get the information you need.
For more see http://blogs.msdn.com/b/visualstudioalm/archive/2014/04/03/performance-profiling-on-windows-phone-8-1-with-visual-studio.aspx
You have to connect that device using USB-EEM.
Then you can connect windbg for that device by below methods on host:
1. open windbg.
2 go to file-> kernel dbug
3.skip port number, enter the key value as 1.2.3.4.
Then restart your device.
will connnect to your device.

Summary
I'm developing firmware and a PC test application for a custom USB device, using the STM32F072 Discovery board. The device includes Microsoft Windows Compatible IDs (WCIDs) to enable automatic installation of the WinUSB driver on the PC.
The device is enumerated correctly on other Windows 10 hosts, but not on my Windows 10 development PC. My development PC had previously tried to enumerate the device when it had the same VID/PID combo, but with different descriptors/metadata. If I change the PID to some other number (new to my development PC), it does enumerate correctly.
Questions
How can I get this to work with my desired VID/PID combo on my development PC?
Is Windows caching USB metadata the cause of the failed enumeration on this one PC?
What are best practices on the (Windows) PC-side for testing/development of USB device firmware, during the stage when device descriptors and metadata are in flux? Is it possible to avoid chewing up PIDs just to avoid the Windows caching?
Details
Because of the way Windows caches USB descriptors and the like from previous enumerations, during firmware development, I was incrementing the device Product ID (PID) in the firmware after each time I made other changes, to ensure that Windows wasn't caching things from previous iterations of the descriptors, and messing up stuff that would otherwise work.
Now I've gotten the device to enumerate successfully on Windows 7, 8, and 10 PCs as a WinUSB device, and I've established communication. But when I change the firmware back to using the VID/PID that I started with, and then connect the device to my development PC, it shows up in Device Manager under "Other devices" with an error icon. I think this is because my (Windows 10) development PC previously had seen this VID/PID combo as having different descriptors, so it's getting confused by some bad cached stuff.
I've tried using regedit to delete the device's registry keys under HKLM\SYSTEM\CurrentControlSet\Enum\USB\VID_xxxx&PID_yyyy, but the problem persists. (Also, I get an error, because it can't delete the VID_xxxx&PID_yyyy\zzzzzzzzzzzzz\Properties subfolders.) I also tried using USBDeview to uninstall old iterations of the device, but that hasn't made a difference either.
Also of note is that I can no longer pass the device through to Virtual Box virtual machines. I'm not sure what happened there.
Try removing any relevant registry keys of the form:
HLKM\SYSTEM\CurrentControlSet\Control\UsbFlags\vvvvpppprrrrr
The MSDN article Microsoft OS Descriptors for USB Devices says:
The operating system creates a registry entry, named osvc, under this registry key that indicates whether the device supports Microsoft OS Descriptors. If the device does not provide a valid response the first time that the operating system queries it for a Microsoft OS String Descriptor, the operating system will make no further requests for that descriptor.
I know the OP has resolved his issues, but for future reference for anyone else having this problem: I had similar issues while developing a USB device with a vendor-specific class. Specifically, (similar to your experience) I was unable to delete the keys from:
HKLM\SYSTEM\CurrentControlSet\Enum\USB\VID_xxxx&PID_yyyy,
so I had to increment the PID every time I modified my device code.
The reason why these keys can't be deleted is that the Properties registry subfolder is owned by the System user, so even running as Administrator you can't delete this subfolder nor change its permissions.
Running Regedit via PsExec (which is part of the SysInternals suite from Mark Russinovich) from an elevated command prompt with: psexec -s -i regedit.exe runs regedit as System user, which means you can delete that pesky Properties subfolder and the parent VID_xxxx&PID_yyyy keys.
I'm confronted with the same issue and uninstalling the device did not help.
Messing around with the registry makes me feel uneasy.
I still don't see a real answer to question #3.
What worked in my case: open device manager, select the non-working device and do "update driver". Select the driver manually from the list of locally available (Microsoft) drivers.
This did not solve all my problems but at least Windows does not ignore my device anymore and I can continue developing.
EDIT: I found a very helpful description on a github project named WCID Devices by Pete Batard. I strongly recommend reading the section Implementation and the following on this page WCID Devices
there are tools for removing hidden traces of USB devices like USBOblivion http://www.thewindowsclub.com/usboblivion-remove-usb-traces-windows , USBDeview,...
sources of USBOblivion are here: https://sourceforge.net/projects/usboblivion/ (https://www.openhub.net/p/usboblivion)
http://www.techerator.com/2010/05/how-to-remove-hidden-duplicate-copies-of-usb-device-drivers-in-windows/
To Remove TrustedInstaller Owned Registry Keys
Unfortunately the old PsExec trick of running RegEdit doesn't always work. In that case try to use:
ExecTI - Run as TrustedInstaller
Run it to open the ExecTI GUI and enter: C:\Windows\regedit.exe
To repair file and registry permissions
You can also try using the very old tool: subinacl.exe
Example:
subinacl.exe /subkeyreg HKEY_LOCAL_MACHINE\SYSTEM\ControlSet\Enum\USB\VID_0000&PID_0002\
Further described here. And has been shown to still work on Win10.
I need to go through this manual:
https://msdn.microsoft.com/en-us/library/dn197917.aspx?f=255&MSPPError=-2147217396
And I do not understand point 2. It says: "Set the SYSGEN_NETUTILS variable in your OS design to include ipconfig.exe"
Can someone, please, explain what it means and how to do it?
My situation is that I am using Visual Studio 2013 and I want to use it to debug my C++ program on Windows Embedded Compact 2013. Deploying works well for me, but when the exe should be launched I receive error: "A socket operation was attempted to an unreachable network." I hope that your answer will help me to solve this.
Step 2 in the linked description only applies to OEMs who use Microsoft Platform Builder to create their own, customized OS images.
What it means is that setting the SYSGEN_NETUTILS variable includes the ipconfig tool in the image, which can then be used to obtain the IP address of the CE device (this is needed in step 4).
If the ipconfig tool is already included in the image (open a command prompt on the device and execute ipconfig to check), or if you have other means of determining the device IP address, you can ignore step 2 entirely.
The socket error you are getting indicates an unrelated network configuration issue. To fix it, you will need to modify the network settings on either the CE device or on your host PC to bring the two onto the same network, allowing the PC to connect to the device.
I am having really difficult time to cope up with the windows phone emulator.
My ultimate goal is to deploy my application and sniff http requests through fiddler.
I am on Visual Studio 2013 Update 4 on Windows 8.1
Problems which i face
Sometimes the emulator does not start at all and gets stuck "Window Phone OS is starting ".
Here first i get the message of "Attempting to modify switch settings" info dialog. I clicked on ok. Then i get Error dialog of "Windows Phone emulator is unable to connect to the windows phone operating system" "Object reference not set to an instance of an object "(Internal c# error). I click close and it gets stuck at "Windows Phone OS is starting".
if i get past this problem and my application gets deployed. I cannot connect to internet. Even a link in browser does not open.
Now for the rarest of rare times i am able to connect to internet. I am in no way able to sniff http request.
But sniffing is still my secondary problem, but my first issue is to get the emulator run and connect to internet.
Steps which i have performed to troubleshoot.
Hyper-V as a Windows feature is turned on.
My firewalls have been disabled.
I have removed the virtual machines and switch created by Hyper-V manager and let it be created through Visual Studio.
In network connections, disabled and enabled the vEthernet (Windows Phone emulator switch ).
Have also tried ipconfig/renew.
Have gone through lot of msdn posts, blogs, so questions but the behaviour of emulator is pretty inconsistent.
Is there any way i can get emulator logs/info ?
Any help to direct to me to any direction will be hugely appreciated.
UPDATE
only thing which is consistently working for me right now is disabling Hyper-V windows feature and then enabling it again.
Mind the expensive system restarts also. Then adding my user name to Hyper V admin group and then deploying the application.
So whenever i am changing my network i have to perform these steps. Definitely not sustainable
UPDATE 1
So now i have fiddler also acting as a man in the middle. Followed the steps here http://blogs.msdn.com/b/wsdevsol/archive/2013/06/05/configure-the-windows-phone-8-emulator-to-work-with-fiddler.aspx. Couple of thing to change here are the port number and to give the ip number instead of host name.
Also have fiddler always start first and then the emulator. Fiddler is able to sniff the requests happening in emulator. But my application http requests are not going through which is fine if i run without fiddler. I am currently looking into this.
Best Regards,
Saurav
Have you tried to run Visual Studio as Administrator? Sometimes, the user must have highest privileges to run Hyper-V.
I've tried to find an answer to this before posting this question. I've got a windows service running on another machine. I've written the service in C# and the directory from which the service executable runs holds both executable and debug files (.pdb). I'm attempting to remote debug the service for the first time using VS 2012 Remote debugging. I'm able to attach to the service process successfully. However, as this is my first time I'm not sure what I can do next. I've clicked the pause button and that pauses the service on the line ServiceBase.Run(ServicesToRun) which isnt much use to me. The service has a timer which sets off every 30 seconds and will run the code in the timer event.
My question is ... is there a way of stepping through the code using the debugger in such a scenario.
Do I need to have some debug specific code already in my codebase so that when a debugger attaches it will take me to a place in the code from where i can step through the code?
Thanks,
Andrew.
There are several ways to debug your developed remote application or windows service. If you were in your machine(local) that would be simple to debug.
System.Diagnostics.Debugger.Launch();
But as you are in different machine it depends how your both Machines are connected. Which means you have some limitations on debugging remote application/services.
A Quick search gave me the following result that seemed helpful to me for you,
You can use Remote Debugging Monitor that visual studio use for connecting to remote device and debugging. You can have a clear instruction here on How to: Run the Remote Debugging Monitor.
There's another tool which lets you debug remote application's after a proper setup. But it has some limitations or conditions that you must abide by.
Here is the tool named Remote Tool, you can find a detailed setup process from MSDN here on How to: Set Up Remote Debugging.
It has been clearly quoted there about the prerequisites for using this tool. But still I'm rephrasing those again for quick reviewers.
Prerequisites to use Remote Tool for Visual Studio
To debug on a remote device:
The remote device and the Visual Studio computer must be connected over a network or connected directly through an Ethernet cable. Debugging over the internet is not supported.
The remote device must be running the Remote Tools for Visual Studio 2012.
You must be an administrator to install the remote tools on the remote device. To communicate with the remote tools, you must have user access to the remote device.
Feel free to share if you get to a better and working solution.
Thanks for your response. It reminded me to post my solution here for others like me.
The solution is simple (It always is once you know it).
Ensure that you are running the same code on the target machine as you have open in Visual Studio. It has to be the same assembly and version else the debugger will not hit your breakpoints. Ensure you have your breakpoints setup where you want the debugger to break execution. Then attach to the target machine process and wait for the timer to kick in and run the process where you breakpoint is set.
Hope this helps.

I've got a Windows 7 machine set up on Paralells.
Everything is working fine. Can access internet from IE or other browsers on my Parallels.
However, when trying to debug a web application in Visual Studio 2010 (by pressing F5 for example) then my default browser in OSX launches, which is great, with localhost:4243 (or whatever port Cassini has allocated on my vm)
Naturally, this doesn't find anything...
What do I need to do to either my parallels vm, or the settings on OSX to get debugging working? ie- my mac talking to the vm?
Make sure you are on the same network.
Use IIS.
Like so:
Your Win-machine has a name, let's say it's called "myWin7machine". Change "localhost:4243" to "myWin7machine:4243" in the browser.
If this doesn't work (well... it shouldn't) you might have the firewall on or the network not bridged. Let's start with the bridging.
Time to check some basics - be on the same network
Check your IP address. It's "ipconfig" on the Win machine and "ifconfig" on the mac; both run from the command prompt. The IP address should be something like 10.4.... or 192.168... on both. The important thing is that only the last number is different. (this is technically not correct but works for 99% of the cases) If they are equal (except the last) you are bridged - which means both machines are on the same network. If they differ too much you had running the Win machine's network "inside" the Mac's. Go to the settings for Parallels (in windows: move your mouse to the top to show Parallel's menu and go to Devices->Network and something "(bridged)". Wait until the balloons disappear and check ipconfig again.
Check that you can ping the Win machine from the Mac. Ping functionality might be turned off in the Win machine but probably isn't.
Now we know we are on the same network.
Still doesn't work
Can you do http://myWin7machine:4243 from the mac? Well.. you shouldn't be able to.
Can you do it from the Win machine? You should.
IIRC Cassini doesn't talk to strangers. I.e. it doesn't talk to anything but localhost.
If I am wrong - just open port 4243 in the firewall on the win machine and you should be good to go.
But otherwise...
Time to change web server.
Install IIS on the win machine.
In the Mac: surf to http://myWin7machine and see the IIS7 logo show.
If you don't you have a firewall issue. Open port 80. Try again.
If you have come this far then you can surf from the Mac to the IIS on the Win machine.
Time to set up your VS solution
Open the IIS admin GUI. Create a new Site. Let's say you call it MyTestSite. (you can always rename it later) Point it to your VS solution's web. Typically the same folder as web.config resides in. On the win machine: try surfing to "http://localhost/MyTestSite". Your site should show up. You might get an Apppool error.
Now try http://myWin7machine/MyTestSite on the Mac. It should work.
ROCK!
Time to set up debugging in VS
For debugging in IIS you have to connect to the process. In Win7 it requires elevated privileges so either you restart VS as admin or you try to connect and VS will do it for you.
The menu in VS is Debug->Attach to process and you choose w3wp.exe.
This is how you debug faster anyway - by connecting. Restarting your web for every debugging session is a waste of time.
To make connecting faster - use ctrl-alt-p and the continue with using the keyboard.
To make connecting even faster use a macro.
There is more info in these 4 articles: http://www.selfelected.com/tag/iis/
Set a breakpoint. Refresh your browser and the breakpoint should be hit.
Time to hack some code
Good luck!
I'm using Windows 10, VS 2015, Parallels 11 on iMac with OS X El Capitan (10.11.5). The following are the steps that worked for me:
On Windows side:
Get the IP (run ipconfig command in command window)
Get the host name (run hostname command in command window)
In control panel look for Windows Firewall -> Advanced Settings and add a new inbound rule and a new outbound rule. For both make sure you select Port, Allow Connection, TCP and specific IPs. I added a range of IPs 45000 - 45999 but you can select the range you like.
In Visual Studio:
Look for project properties and under web section change Server settings to look something like this.
Instead of "winmac" you will use the host name found in "Windows Side - Step 2". The port can be any number inside the range you setup for your firewall rules.
On Mac OS side:
Update /etc/hosts file. At the end of the file add the IP and host name that we found on steps 1 and 2 of the "Windows side" section. When you finish this step the file should like something similar to this.
Ready to debug:
Now you can start debugging in your Mac from Visual Studio. Make sure that before start the debugging process you select "Open In Mac" option (instead of Chrome or IE in your debugging options in visual studio).
