VS 2013 error when using JSON deserialization method

Question

I created a C # ASP.NET method that simply takes a string property containing JSON, like inside a single class. My problem is that whenever I type .Deserialize method (comment line), Visual Studio 2013 crashes "Unhandled Exception" in the event logs.

public object JSONAsObject() { object obj = new object(); JavaScriptSerializer js = new JavaScriptSerializer(); // obj = js.Deserialize<object>(this._json); return obj; } 

If I write a line in the comments (as indicated above), then delete the comments there without problems, so the problem arises with Intellisense or the way I write code - who has any ideas?

Please let me know if you need this to upgrade to SuperUser.

Edit 1: Just to confirm that this problem occurs at design time and not at run time. VS crash while entering code.

Edit 2: This issue only occurs on this particular line. The system I'm working with is massive and I have never seen a problem before.

Edit 3: The same problem in the new project is potentially a bug in VS 2013, but I don't know what throws an exception in the first place.

Answer 1

As @Jehof explained in the comments, I turned off all VS 2013 extensions that fixed the problem. Enabling each extension one at a time showed that the Bing development assistant caused this problem. There was an update that was not installed - installing this update fixes the problem.

For anyone else with this problem, make sure that VS and all extensions are fully updated.

Answer 2

Visual Studio continues to crash 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 for medium and large projects, which can lead to crashes and instabilities - you can turn off improvements in Tools / Options / Text Editor / Node.js / Completion / Automatic List to avoid this (recommended).

Answer 3

You cannot use an "object", you must use a type.

 Deserialize<T>() 

where T is a type, cannot be an "object"
