Ever since I started coding in Visual Studio 2012, I'm seeing the following warning in eConnect projects:
Warning:
There was a mismatch between the processor architecture of the project being built "MSIL" and the processor architecture of the reference "C:\Projects\LRVTools\LRVLibrary\bin\Debug\LRVLibrary.dll", "x86". 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.

It's not a serious thing, but it is an irritation. This article briefly discusses the warning and how to remove it.
