Json.NET 4.0 Release 8 – Bug fixes
This is a relatively minor release that fixes all outstanding bugs and adds a couple of enhancements.
NuGet Silverlight/Windows Phone Assemblies No Longer Strong-Named
The big change this release is that the Silverlight/Windows Phone NuGet assemblies are no longer strong-named.
Unfortunately Silverlight/Windows Phone applications do not support redirecting strong-named assemblies like normal .NET apps do via <assemblyBinding> configuration. If a Silverlight or Windows Phone application uses two libraries that each reference a different version of Json.NET then the only solution is to get the source code for the libraries and recompile them yourself to use the same version of Json.NET – not ideal.
From 4.0.8 the NuGet assemblies for Silverlight/Windows Phone are no longer strong-named. If you do need strong-named versions of Json.NET for SL/WP then they are still available in the Json.NET zip download from CodePlex in the Bin\Silverlight\Signed and Bin\WindowsPhone\Signed zip folders. I don’t recommend using them with reusable SL/WP libraries because of the reasons above.
Json.NET Assembly Redirection
In case you ever do end up with multiple libraries that reference different versions of Json.NET in a normal .NET application, here is the configuration to fix your application use one version of Json.NET:
Update newVersion as needed to the version of Json.NET you are using. This can be found in Visual Studio by right-clicking on Newtonsoft.Json reference and selecting Properties.
