Solved Global.ItemManager on C#?

How is the global.ItemManager instruction in C#? I search in Assemblu-CSharp, Oxide.Core and Oxide.Ext.Rust but i can't find anything.

I'm trying with

Code:

ItemManager itemManager = ItemManager.Instance;

or

Code:

ItemManager itemManager = SingletonComponent<ItemManager>.Instance;

But i have an error saying that not have access to a member (for example: ItemManager.FindItemDefinition(string))

 

just:

Code:

ItemManager.FindItemDefinition(itemname)

 

xD Thnx
I didn't see it was a static method
