AssetDatabase BUILD ERROR u3f5

Hello Team !
here is my code :

function IsThisABug()
{
	var _billboard=AssetDatabase.LoadAssetAtPath("Assets/Prefabs/billboard.prefab",GameObject);
}

this code seems OK and runs nice at runtime but I get the following ERROR if i try to build (a standalone &a webplayer -i didn’t try builds for IOS, WII; Androïd,etc…) :

from Console Message :Assets/scripts/bug.js(3,24): BCE0005: Unknown identifier: 'AssetDatabase'.'.
and then from Console Message :

Error building Player because scripts had compiler errors
UnityEditor.HostView:OnGUI()

:shock:

AssetDatabase class is an Editor class so it works only in Editor…
