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


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

Question:

Tag: .net,json,jsonobject

I am using .NET Framework 4.5 and I'm having this issue. The type or namespace 'Json' does not exist in the namespace 'System'

So, I tried to Install-Package System.Json -Version 4.0.20126.16343 but I had this issue afterwards.

The type 'System.Uri' is defined in an assembly that is not referenced. You must add a reference to assembly 'System, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089'

Source: https://www.nuget.org/packages/System.Json

Any ideas would be really appreciated!


Answer:

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

If you have a console application, I could recommend two options:

Both are capable of reading and writing JSON. I find the JSON.NET library easier to use and more feature complete.
