marten: Install-Package Marten -Pre fails in Visual Studio due to missing dependency.

• Visual Studio 2015 Community Update 3
• Fresh console application with no other packages.
• Execute Install-Package Marten -Pre from package manager console.

Install-Package : Failed to add reference. The package 'Marten' tried to add a 
framework reference to 'System.Linq.Expressions' which was not found in the
GAC. This is possibly a bug in the package. Please contact the package owners
for assistance.

It might just be my machines (Desktop + Laptop). If so, please let me know how to fix.
