  62&gt;C:\Windows\Microsoft.NET\FramModuleork\v4.0.30319\Microsoft.Common.targets(1578,5): warning MSB3270: There was a mismatch between the processor architecture of the project being built "MSIL" and the processor architecture of the reference "D:\Autobuild\10.0\dotNET_tc\My.Legacy\bin\x64\Release\My.Legacy.dll", "AMD64". This mismatch may cause runtMye 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.

  <p>We change host for out virtual build machine, we reinstall OS on build machine but error still appeared sometime.</p>
  
  <p>Any thoughts?</p>
  
  <p>P.S. we start builds from Jenkins and TeamCity. In both error was reproduced.</p>
