I've created a C# ASP.NET method which simply takes a string property containing JSON, both inside the same class. My issue is that whenever I type the .Deserialize method (the commented line) Visual Studio 2013 crashes with an "Unhandled Exception" in event logs.
public object JSONAsObject()
{
object obj = new object();
JavaScriptSerializer js = new JavaScriptSerializer();
// obj = js.Deserialize<object>(this._json);
return obj;
}
If I write the line in comments (as above) then remove the comments there's no problem so the issue appears to be with Intellisense or the way I'm writing the code - anyone have any ideas?

Please let me know if this needs to go onto SuperUser.
Edit 1:
Just to confirm this issue occurs during development, not at runtime. VS crashes when I am typing the code.
Edit 2:
This issue only occurs with this particular line. The system I'm working with is massive and I've never seen the problem before.
Edit 3:
Same issue in a brand new project - potentially a bug in VS 2013 but I don't know what's throwing the exception in the first place.
As #Jehof suggested in the comments I disabled all of my VS 2013 extensions, which fixed the problem. Enabling each extension one by one showed that the Bing Developer Assistant was causing the problem. There was an update which hasn't installed - installing this update fixed the problem.
To anyone else with such a problem, ensure VS and all extensions are fully updated.
Visual Studio keeps crashing Visual Studio when working with TBS and Angular JS.
System.NullReferenceException was unhandled
Additional information: Object reference not set to an instance of an object.
IntelliSense uses large amounts of memory on medium/large projects which can result in crashes and instability - you can turn off completions in Tools/Options/Text Editor/Node.js/Statement completion/Auto list members to avoid this (recommended).
You can not use "object", you must use a type.
Deserialize<T>()
, where T is a type, cannot be "object"

I have an application on my desktop. The application folder contains a .exe file and .config file.
The config file shows Rsa Key.
I am swapping PC's and would like to run the application on new PC. I have tried simply copying the folder over but the app wont run. The windows event viewer error:

I also have .NET framewirk installed and up to date on target achine
How do i go about copying the app to a different. I do have access to server where the database and source code are hosted.
I have zero experience in deploying/compiling .NET apps.
It looks like the RSA key that was generated may have been machine specific. Most likely you will need a new one generated for your new machine. Another option would be to take an image of the machine and try to run it in something like virtual box. Lastly, you could look at figuring out what is making it machine-specific, something like values in the registry or mac addresses for the piece needed to get it working. But that last one is like looking for a needle in a very large haystack... Best option is the first, figure out how to regenerate the RSA key.
I'm having a window service and tried to start it by using ServiceController class from an windows application and it's working fine for few systems, but this is failing in few systems and giving exception like below.
Below is the sample code that I've written to start the service, also I don't want to do any manual changes to the target machine in order to start the service.
ServiceController service = new ServiceController("SampleService");
if (service.Status.Equals(ServiceControllerStatus.Running) || service.Status.Equals(ServiceControllerStatus.StartPending))
{
Bservice.Stop();
}
service.WaitForStatus(ServiceControllerStatus.Stopped);
service.Start(arguments);
service.WaitForStatus(ServiceControllerStatus.Running);
Am I missing anything from the code snippet? or please help me out how can i get rid of this.
Even I've commented out all the code in the service like it's empty service now, but with code and without code I'm getting same below error any idea??

The above exception is coming only when I install service using commad 'sc create "service name" ...' but when I install service using 'Installutil.exe "service"' then I'm getting no issues don't know why? Any reasons??
I have a program which is a authoring tool for making courses. I decided to create a screen recording feature for it using camstudio. The code I used to launch the exe is:
Process process = new Process();
process.StartInfo.FileName = "Recorder.exe";
process.StartInfo.Arguments = "";
process.Start();
When I am running the program in visual studio and step through the code it works fine and launches the recorder.exe with no errors. BUT when I make an installer for the project in visual studio 2010 and install the program, the program crashes when I press the button which should launch the recorder.exe.
I checked the windows error log and here is what it told me:

Found a similar unanswered question on here: Why i'm getting a win32exception once i'm starting the Process?
If more information is need please let me know and I'll provide as much as I can. I have seen similar questions on here and other forums but none have given me the answer.
Thanks, Jim
(Per Josh Gallagher's suggestion, reposting comment as answer)
That is likely an issue with current working directory (cwd). IIRC, VS actually sets cwd to the output folder when launching your exe in debug. However, in read world, cwd really depends on how exe is launched and does not necessarily point to the same folder where your target exe is.
You can actually test it easily by simply writing the value of Environment.CurrentWorkingDirectory (or something like that) and see what it points to. alternatively try to hardcode full path for now while troubleshooting. Either way, my money are on the fact that your context for execution is in wrong dir.
Wrap your code in
try
{
Process process = new Process();
process.StartInfo.FileName = "Recorder.exe";
process.StartInfo.Arguments = "";
process.Start();
}
catch(Exception e)
{
//Log using your logger the full error message.
}
This will give you indication of what's faulting your program. Difference between success in VS and failure in real world is likely some context such as current working directory. But at least this will give you information as to what is the nature of the error that causes it to crash.
The big problem I am trying to solve is identify why in one of our managed application we are receiving from time to time a access violation exception (0xc0000005).
Recently, on a completely different application we started to receive a NullReference exception (which is a know bug now), but it's followed by a (0xc0000005) error. I wonder if this is normal behaviour or it is related to our 'big problem'.

Yes, that's normal. There is no such thing as a "null reference exception" in Windows. These kind of pointer faults are reported by the processor with a general protection fault trap, that generates an access violation exception in the operating system. Exception code 0xc0000005.
Windows setS up the virtual memory for a process by always leaving the bottom 64KB, starting at address 0 unmapped. Specifically to detect pointer bugs, they are very common in programming. A NULL pointer will thus always trip the processor fault. As well as addresses somewhat larger than 0, generated when a program tries to access a field of an object through a null pointer.
The CLR intercepts the native access violation exception and looks at the address that caused the exception. If it is located within that 64KB address range then it raises System.NullReferenceException. If it is not then it raises System.AccessViolationException.
The top snippet were the diagnostics generated by Windows, the bottom by the CLR. The top one just shows the native exception code, Windows doesn't know anything about managed exceptions.
For me there was an overlay that would show some hardware info that was causing the error. Once I turned the overlay off (ASUS GPUTWEAK II), it solved the issue, make sure that you don't have 3rd party programs interfering with your own! :)
I have a WPF/Winforms application that works perfectly fine on XP, as well as Win 7. But on Vista, ONLY sometimes - may be 20-30% of the time I see this:
Any help is much appreciated

It looks like this exception occurred when the application tried to create a BitmapImage, could it be that your system blocks or locks access to a specific file that is needed to load the image from?
WIC, what you see on the top of the stack trace, is the underlying imaging library for WPF. It is a COM component, written in C++. It is not unusual for unmanaged code to bomb with AccessViolation. You could possibly wring some more info out of the stack trace by enabling unmanaged code debugging and enabling the Microsoft Symbol Server.
Nevertheless, the odds are not good to put any kind of dent in this problem. The only knobs you can tweak is the image itself, it might be corrupt in a way that makes the code bomb. And make sure that service pack 1 is installed on the machine. Beyond this, you'll need the help from Microsoft Support. They'll need a minidump of the crashing program and the image that causes the trouble.
Thanks a lot - and very helpful. Turning on unmanaged code debugging led me to the problem being "This indicates memory is corrupt elsewhere". Since I didnt too much finagling with memory, I knew it must have been one of the outside dlls that were being referneced. IT turns out that ICSharpCode.TextEditor.dll is the root of the issue, and updating to the latest version of it fixed it!!!
