Visual Studio 2010无法添加Newtonsoft.Json库

Question

I've got a Problem with Visual Studio 2010 and the Newtonsoft.Json library.

A few hours ago nothing was wrong with my project, but now it throws this error

The type or namespace name 'NewtonSoft "could not be found. (Missing a using directive or an assembly reference?)

--I just saw that the Reference was deleted and i can't re-add the NewtonSoft.Json library.

Answer 1

You can use the package manager console to remove the package, if you're having trouble getting NuGet to uninstall or reinstall it using the GUI:

Uninstall-Package Newtonsoft.Json

Be sure you've selected the right target project from the dropdown at the top of the console if your solution contains several projects.

Answer 2

确保项目目标的.NET Framework版本与Json.NET nuget软件包所需的版本相同或更高。
