  • Json.NET 12.0 Release 1 - .NET Foundation, NuGet and Authenticode signing, SourceLink and more

    .NET Foundation

    Json.NET has joined the .NET Foundation! The .NET Foundation is an independent organization dedicated to fostering the .NET open source community. The .NET Foundation provides technical and legal guidance .NET open source projects. Joining the .NET Foundation ensures that Json.NET stays open and supported into the future.

    NuGet package and Authenticode signing

    Json.NET 12 is the first release to sign the *.nupkg using NuGet package signing and sign the assembly files using Authenticode. Although it isn't a common request, some users of Json.NET have asked for signed binaries because of company policy. This feature is made possible by the .NET Foundation, who offer code signing certificates and a signing service to member projects.

    Better debugging with SourceLink

    SourceLink is an neat technology that links a library to its source code. Originally created in the community by @ctaggart, SourceLink has been adopted by Microsoft and is supported in Visual Studio. This release adds SourceLink support to Json.NET, making it possible to step into the Json.NET source code as you debug your application.

    And lots more

    JSON Path supports JavaScript's strict equality operators (=== & !==), StringEnumConverter can use a NamingStrategy and is faster, JavaScriptDateTimeConverter supports JavaScript date constructors with multiple arguments, there is a new option on JsonMergeSettings for case insensitive merging of property names, serializing Span<T> properties no longer errors, and dozens of other new features and bug fixes.
