I have a problem regarding NewtonSoft.
I have a solution with 3 projects for example. Project A has reference points to Project B and Project C, Project B also has reference points to Project C. Both B and C has NewtonSoft assembly. Project C has function to get JsonMediaTypeFormatter:
new JsonMediaTypeFormatter()
the function is called by all three project. Both Project B and C can call the function without any problem. But when project A calls the function, it throws error:
Method not found: 'Void Newtonsoft.Json.Serialization.DefaultContractResolver.set_IgnoreSerializableAttribute(Boolean)'
Something I notice that even project A does not have NewtonSoft reference, when project is built, the Newtonsoft.json.dll is copied to its bin\Debug folder. I guess it is because of Newtonsoft assembly is set to true for Copy Local optoin in both project B and C. If I manually delete this dll from Project A's bin\Debug folder, problem solved.
My question is why project A can hit the exception, and is there any solution except manually delete Newtonsoft dll from project A's bin\Debug folder? Set Copy Local to false is not a option because it will prevent dll deploying to their own bin folder for project B and C too.
Any suggestion would be appreciated.
Update
Here is my code snippet
using Newtonsoft.Json.Converters;
using Newtonsoft.Json.Serialization;
using System.Net.Http.Formatting;
var jsonSerializerSettings = new JsonSerializerSettings
{
Formatting = Formatting.Indented,
ContractResolver = new CamelCasePropertyNamesContractResolver()
};
var dateConverter = new IsoDateTimeConverter
{
DateTimeFormat = "yyyy'-'MM'-'dd'T'HH':'mm':'ss'Z'"
};
jsonSerializerSettings.Converters.Add(dateConverter);
var formatter = new JsonMediaTypeFormatter
{
//SerializerSettings = jsonSerializerSettings
};
If I comment out SerializerSettings, it works fine.
If I uncomment this line, application will return such issue.
If I just pass in blank setting to it
var formatter = new JsonMediaTypeFormatter
{
//SerializerSettings = new JsonSerializerSettings{}
};
I got error:
Method not found: 'Void System.Net.Http.Formatting.BaseJsonMediaTypeFormatter.set_SerializerSettings(Newtonsoft.Json.JsonSerializerSettings)'
I think it may be related to different System.Net.Http.Formatting references inside projects, but I checked reference setting, they are all point to file
packages\Microsoft.AspNet.WebApi.Client.5.2.3\lib\net45\System.Net.Http.Formatting.dll
This code resides in Project C. It only failed when called by Project A, project B and C can call it without any problem. Once I remove NewtonSoft.Json.dll from Project A bin\Debug folder, it works in project A calls too.
Do you know what happened? and how can I check if there still have different reference version conflicit in project?
Thanks,
