Is using the system.text.json no longer possible for serializing / deserialiing in c#

Question

As described in the official microsoft docs which has been Updated in September of 2019 it says that using system.text.json for serializing or deserializing can be done.

https://docs.microsoft.com/en-us/dotnet/standard/serialization/system-text-json-how-to

However when I tried that in a program I was working on , I kept getting the error using system.text.json does not exist

This made me stumble upon this Stack Overflow Question

The type or namespace name 'Json' does not exist in the namespace 'System' (are you missing an assembly reference?)

In which as shown above says that the

package is discontinued and shouldn't be used any more.

Is there any update on this ? or Is there any way I can work around with system.text.json

Answer 1

You just have to install the System.Text.Json NuGet package.

1. In Solution Explorer select your solution (at the root of the tree) and click with right mouse button.
2. In the contextual menu choose Manage NuGet Packages for Solutions...
3. In the window that will appear, click on Browse on the top.
4. In the search textbox type System.Text.Json
5. Select the package, then on the right select all the project of your solution for which you want the package to be installed, and then click on the Install button.
