How do I solve this problem with Visual studio 2010?

Question

Warning 4 The currently targeted framework ".NETFramework,Version=v4.0,Profile=Client" does not include "Microsoft.Build, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" which the referenced assembly "Microsoft.Data.Schema, Version=10.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" depends on. This caused the referenced assembly to not resolve. To fix this, either (1) change the targeted framework for this project, or (2) remove the referenced assembly from the project. TUGABASEMENT
