The mesosphere is a layer of Earth's atmosphere. The mesosphere is directly above the stratosphere and below the thermosphere. It extends from about 50 to 85 km (31 to 53 miles) above our planet.Temperature decreases with height throughout the mesosphere. The coldest temperatures in Earth's atmosphere, about -90Â° C (-130Â° F), are found near the top of this layer.redit: Randy Russell, UCAR. The mesosphere is a layer of Earth's atmosphere.

Entity Framework (EF) is an open source object-relational mapping (ORM) framework for ADO.NET. It was a part of .NET Framework, but since Entity framework version 6 it is separated from .NET framework.
Entity Framework is an Object Relational Mapping (ORM) Framework for the .NET Framework. Entity Framework returns the data in your database as an object. Entity Framework is actually written on top of ADO.NET, meaning under this framework, we are still using ADO.NET. So we cannot say that Entity Framework is a replacement of ADO.NET.
