MSB3270 Warnings in Visual Studio

[BMurri]

When building in Visual Studio, three of the unit test projects report warnings like:

Warning	MSB3270	There was a mismatch between the processor architecture of the project being built "MSIL" and the processor architecture of the reference "[full-path-to-the-built-x64-binary-being-tested].dll", "AMD64". This mismatch may cause runtime failures. Please consider changing the targeted processor architecture of your project through the Configuration Manager so as to align the processor architectures between your project and references, or take a dependency on references with a processor architecture that matches the targeted processor architecture of your project.

This warning is benign and can be suppressed.
