I had the same problem a few weeks ago. My problem with the trust medium level was that my cshtml had a "~" at the javascript tag, like:
<script src="~/Scripts/foo.js"></script>
Removing the "~" simply resolved my problem.
It's a weird error because it points to a Razor declaration instead of the "~" line. Although the "~" is a special Razor symbol in this case.
Hope this might help.
I am working with ASP.NET MVC 5 Web Api.
I am having existing application with many api's.
Recently I have implemented custom JsonConverter which will convert Date as per timezone.
public class CustomInfoConverter : JsonConverter
{
public override bool CanConvert(Type objectType)
{
return objectType == typeof(CustomType);
}
public override bool CanRead
{
get
{
return false;
}
}
public override bool CanWrite
{
get
{
return true;
}
}
public override void WriteJson(JsonWriter writer, object value, JsonSerializer serializer)
{
var customType = (CustomType)value;
if (customType == null || null== customType.TimeZone) return;
//DateTime currentDateTime = customType.Date??DateTime.Now;
DateTime currentDateTime = DateTime.SpecifyKind(customType.Date ?? DateTime.Now, DateTimeKind.Unspecified);
DateTime userDateTime = TimeZoneInfo.ConvertTimeFromUtc(currentDateTime, customType.TimeZone);
customType.Date = userDateTime;
JsonSerializer innerSerializer = new JsonSerializer();
foreach (var converter in serializer.Converters.Where(c => !(c is CustomInfoConverter)))
{
innerSerializer.Converters.Add(converter);
}
innerSerializer.Serialize(writer, customType);
}
public override object ReadJson(JsonReader reader, Type objectType, object existingValue, JsonSerializer serializer)
{
throw new NotImplementedException();
}
}
After implementing this custom JsonConverter all api are working except one api, which is throwing below exception
{"Message":"An error has occurred.","ExceptionMessage":"The

You can refer to this link for more details.
The problem looks to be that, in certain situations, you are returning from WriteJson() without writing anything, specifically when customType.TimeZone == null:
var customType = (CustomType)value;
if (customType == null || null== customType.TimeZone) return;
Doing so will result in an invalid JSON object, because the property name will already have been written by the caller, resulting in:
{
"customType":
}
Trying to do this results in the exception you are seeing.
Instead, you need to prevent the property itself from being serialized. That's not possible in the converter however, it needs to be done in the containing type.
To avoid serializing a property with a null value, you should set NullValueHandling = NullValueHandling.Ignore in serializer settings, or on the property itself:
public class ContainerClass
{
[JsonProperty(NullValueHandling = NullValueHandling.Ignore)]
public CustomType CustomType { get; set; }
}
To prevent serializing your property when its TimeZone property is null, you should use conditional property serialization by adding a ShouldSerializeXXX() method to the containing type, where XXX exactly matches your property name:
public class ContainerClass
{
public CustomType CustomType { get; set; }
public bool ShouldSerializeCustomType()
{
return CustomType != null && CustomType.TimeZone != null;
}
}

The RelatedExceptions property is 'readonly' for the (de)serializer.
Add a set to the property as well.
The same goes for the other private setters.
They need to be public for the serializer to set them.
Given the following class structure, which includes a dictionary of derived objects, how can I serialize and deserialize using NewtonSoft’s Json library? When I deserialize, I am getting an exception. It looks like it is having issues reconstituting the dictionary.
[JsonObject(MemberSerialization.OptIn)]
public class GameObject
{
[JsonProperty]
public string Id { get; set; }
[JsonProperty]

public GameObject()
{
Components = new ConcurrentDictionary<string, Component>();
}
}
[JsonObject(MemberSerialization.OptIn)]
public class Component
{
[JsonIgnore] // Ignore circular reference
public GameObject GameObject { get; set; }
public Component()

}
[JsonObject(MemberSerialization.OptIn)]
public class TestComponent : Component
