title: Visual Studio error There was a mismatch between the processor architecture of the project being built msil and the processor architecture
body: <p>I have a <code>.NET</code> project and when I try to build it shows me the following error:</p>
  
  <blockquote>
    <p>There was a mismatch between the processor architecture of the project being built "MSIL" and the processor architecture of the reference <code>"C:\WINDOWS\Microsoft.NET\Framework\v4.0.30319\\mscorlib.dll"</code>, <code>"x86"</code>. 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.<code>Showpad.Salesforce</code>    </p>

  <p>any one help me to solve that please.</p>
