c# - ALINK : warning AL1073: Referenced assembly 'mscorlib.dll' targets a different processor

Question

We are using VS2013 and .Net 4.5.1(recently migrated, but this error is there from .Net 4.0) . This error occurs only when compiling the project in platform target x64. Is this really a error which will break in runtime? Why MSBUILD does not resolve this mrcorlib.dll properly ? This happens only in projects which were created in VS2010 and does not occur in newly created projects. What am I missing here. All my third party assemblies are in x64bit.

In TeamCity build server, I get following error:

Answer 1

While the bug referenced by @jero2rome is closed as Won't Fix, VS2015 RC w/ .NET 4.6 no longer emits this warning:

From VS2013/.NET 4.5.1, I would see the same issue:

ALINK : warning AL1073: Referenced assembly 'mscorlib.dll' targets a different processor [c:svnprojectMyComponent.csproj]

With VS2015 RC/.NET 4.6, no warning is emitted:
