无法加载文件或程序集“ Newtonsoft.Json”

Question

I am using Nhibernate in my MVC3 site. I have 4 tables in database and a service which is used by the site to get data from database. Now I am getting this error :

Could not load file or assembly 'Newtonsoft.Json, Version=3.5.0.0, Culture=neutral, PublicKeyToken=30ad4fe6b2a6aeed' or one of its dependencies. The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040)

I found out that by installing the Newtonsoft.Json by NuGet instead of adding reference to its dll solves the problem, so I did that and it solved the problem. When i debug all works fine. But when I publish and upload on my staging server, it gives the error I mentioned above.

Also, please note that I have 3 methods in my service, but only one gives the error, rest all works fine. And even that one method works fine locally. Just cannot on staging.

Edit: Now i uninstall the Newtonsoft.Json by NuGet and then i added reference to Newtonsoft.Json dll kept in the Bin folder of the Project. Again its working locally but not on server.

Why so?

Please reply.

Thanks.

If it works on your system locally, but does not work on the server. I would assume you have some library installed on your PC that is not available on your server.

What library could be missing is hard to say, try looking at the references in your project and see if you are referencing libraries that might be using libraries that you have installed locally.
