Namespace:  System.Data.Entity
Assembly:  EntityFramework (in EntityFramework.dll)

public static IQueryable<T> AsNoTracking<T>(
	this IQueryable<T> source
where T : class

Type Parameters


The element type.

Type: System.Linq.IQueryable<T>
A new query with NoTracking applied, or the source query if NoTracking is not supported.

Usage Note

In Visual Basic and C#, you can call this method as an instance method on any object of type IQueryable<T>. When you use instance method syntax to call this method, omit the first parameter. For more information, see http://msdn.microsoft.com/en-us/library/bb384936(v=vs.103).aspx or http://msdn.microsoft.com/en-us/library/bb383977(v=vs.103).aspx.

This method works by calling the AsNoTracking method of the underlying query object. If the underlying query object does not have a AsNoTracking method, then calling this method will do nothing.
