Silverlight文件未找到Newtonsoft反序列化中的System.Runtime.Serialization

试图反序列化JSON时出现异常。据我了解，这个文件是由用户本地文件系统上的Silverlight运行时提供的，不需要包含在XAP文件中。Silverlight文件未找到Newtonsoft反序列化中的System.Runtime.Serialization

T result = default(T); 

result = JsonConvert.DeserializeObject<T>(data);

任何想法为什么我得到这个错误？

检查您的数据是否为空值。布尔变量中的空值会抛出奇怪的错误。 – bperreault 2012-04-20 01:41:35

出于兴趣是您的程序集引用，System.Runtime.Serialization，标记为“复制本地”= true？ – 2012-04-20 08:48:17

我尝试过使用Copy Local = false和Copy Local = true，并且两次失败。我将运行测试以确保值不为空。我可以保证该值永远不会为空，但它将是'{}'来表示一个空数组。 – 2012-04-20 12:13:35

的问题是，我们有一个Newtonsoft.Json.dll内置的Silverlight 4，这是4.0.5.14411版本它不是为Silverlight 5构建的。当Visual Studio构建解决方案时，它将项目正确映射到正确的System.Runtime.Serialization dll。在使用MSBUILD的TFS中排队构建不会。

我升级到最新版本，并解决了问题。
