使用JSON反序列化方法时VS 2013崩溃

Question

我创建了一个C#ASP.NET方法,它只需要在同一个类中包含一个包含JSON的字符串属性.我的问题是每当我键入.Deserialize方法(注释行)时,Visual Studio 2013在事件日志中崩溃并出现"未处理的异常".

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

如果我在评论中写下这一行(如上所述)然后删除评论没有问题,所以问题似乎是Intellisense或我编写代码的方式 - 任何人都有任何想法？

如果需要进入SuperUser,请告诉我.

编辑1:只是为了确认在开发期间发生此问题,而不是在运行时.我在输入代码时VS崩溃了.

编辑2:此问题仅发生在此特定行.我正在使用的系统是庞大的,我以前从未见过这个问题.

编辑3:一个全新的项目中的相同问题 - 可能是VS 2013中的一个错误,但我不知道什么是首先抛出异常.

Answer 1

正如@Jehof在评论中建议我禁用了所有VS 2013扩展,这解决了问题.逐个启用每个扩展程序表明Bing Developer Assistant导致了问题.有一个未安装的更新 - 安装此更新解决了该问题.

对于有此类问题的其他任何人,请确保VS和所有扩展程序都已完全更新.
