This MSDN thread explains how to fix it.
Either disable incremental linking, by going to
Project Properties -> Configuration Properties -> Linker (General) -> Enable Incremental Linking -> "No (/INCREMENTAL:NO)"
or install VS2010 SP1.
Edits (@CraigRinger): Note that installing VS 2010 SP1 will remove the 64-bit compilers. You need to install the VS 2010 SP1 compiler pack to get them back.
This affects Microsoft Windows SDK 7.1 for Windows 7 and .NET 4.0 as well as Visual Studio 2010.
