Versioning
Just like any other Visual Studio SDK assemblies, extensions must reference lowest version matching the lower bound of supported Visual Studio versions. For instance, if the extension supports Visual Studio 14.0, 15.0, and 16.0, then it must reference the 14.0 SDK assemblies.
Binding redirects
When referencing a lower version of Newtonsoft.Json than ships in Visual Studio, a binding redirect is in place to automatically change the reference to the later version at runtime. Here’s what that looks like in the devenv.exe.config file of Visual Studio 15.0:
Introduction

What is Newtonsoft.JSON?
Newtonsoft.Json has a TypeNameHandling setting that adds type name metadata to the JSON while serializing. It uses the metadata while deserializing to do polymorphic deserialization. System.Text.Json can do a limited range of polymorphic serialization but not polymorphic deserialization.
What is Newtonsoft.Json ObjectCreationHandling?
The Newtonsoft.Json ObjectCreationHandling setting lets you specify that objects in properties should be reused rather than replaced during deserialization. System.Text.Json always replaces objects in properties. Custom converters can provide this functionality.
What is System.Text.Json?
System.Text.Json is strict by default and avoids any guessing or interpretation on the caller's behalf, emphasizing deterministic behavior. The library is intentionally designed this way for performance and security. Newtonsoft.Json is flexible by default. This fundamental difference in design is behind many of the following specific differences in default behavior.
Does Newtonsoft.JSON serialize by value?
By default, Newtonsoft.Json serializes by value. For example, if an object contains two properties that contain a reference to the same Person object, the values of that Person object's properties are duplicated in the JSON.

However, in System.Text.Json, TKey must be a primitive type, not a custom type. For more information, see Supported key types. Caution.

Does Newtonsoft.JSON throw exceptions?
Newtonsoft.Json can be configured to throw exceptions during deserialization if the JSON includes properties that are missing in the target type.

What is a system.text.json.utf8jsonreader?

Binding Redirects
- When referencing a lower version of Newtonsoft.Json than ships in Visual Studio, a binding redirect is in place to automatically change the reference to the later version at runtime. Here’s what that looks like in the devenv.exe.configfile of Visual Studio 15.0: It makes sure that when an assembly references a version of Newtonsoft.Json that is older than 8.0.0.0, it automatically red…

If you absolutely need a newer version than shipped by Vi…
