Error when installing Json.Net to a project targeting Windows Phone 7

I tried installing Json.Net via NuGet using the command install-package newtonsoft.json.

I got an error like the one shown below. How can I resolve this?

Install-Package Newtonsoft.Json
Installing 'Newtonsoft.Json 6.0.6'.
Successfully installed 'Newtonsoft.Json 6.0.6'.
Removing 'Newtonsoft.Json 6.0.3' from ReadJSON.

Install failed. Rolling back...
Install-Package : Could not install package 'Newtonsoft.Json 6.0.6'. You are trying to install this package into a project that 
targets 'Silverlight,Version=v4.0,Profile=WindowsPhone71', but the package does not contain any assembly references or content files 
that are compatible with that framework. For more information, contact the package author.

Support for Windows Phone 7 and Silverlight 4 was removed from Json.Net in version 6.0 (source). If you still need to target WP7 / SL4, then you will need to use Json.Net v5.0.8 instead. You can install this by using the following command in the Package Manager console:

Install-Package Newtonsoft.Json -Version 5.0.8
