After the update
we're having this issue when trying to build our project.
The needed nuget package it's already added and even adding the Telerik.DataSource as a package that's not needed in theory we're not able to build.
Error CS0012 The type 'CompositeFilterDescriptor' is defined in an assembly that is not referenced. You must add a reference to assembly 'Telerik.DataSource, Version=2.1.3.0, Culture=neutral, PublicKeyToken=29ac1a93ec063d92'.
