Project using PCL 'TPL Dataflow' won't compile when targetting .NET 4.5.2 - task-parallel-library

Question

I'm using Windows 7 Pro x64 SP1 and Visual Studio 2012 Update 4. I can't get my VB.NET WPF project to compile when using the TPL Dataflow package and .NET 4.5.2. I've created a base project with nothing except this code and compile only for x64:
Imports System.Threading.Tasks.Dataflow
Class MainWindow
Dim test As New System.Threading.Tasks.Dataflow.BufferBlock(Of String)
End Class
I've tried adding the facade reference to System.Runtime.dll and System.Diagnostics.Tracing.dll with no effect. It compiles fine if I change to .NET 4.5. I must have a reference to 4.5.2 because of other features that will be in the project that require it.
Specific errors:

Solution:
It turns out the Microsoft .NET Framework 4.5.2 Developer Pack I was using had a bug that wouldn't let PCLs compile correctly.
I downloaded and installed the updated version of the Microsoft .NET Framework 4.5.2 Developer Pack from http://support.microsoft.com/kb/2901951 and my application was able to compile without errors.

Answer 1

There is a ticket on connect specifying the use of .NET 4.5.2 with PCL libraries causing builds to fail.
This was fixed in the Microsoft .NET Framework 4.5.2 Developer Pack
When you recompile a Microsoft .NET Framework 4.5.1 application that uses .NET portable libraries to target the Microsoft .NET Framework 4.5.2, you receive the following error message during compilation:
The type '{type}' is defined in an assembly that is not referenced. You must add a reference to assembly '{assembly}'
