title: Requirement of 64-bit version DLLs in a .NET project
body: <h3>Introduction</h3>
  <p>I'm working on a .net project, in which I'm using some 32-bit version DLLs. The list of DLLs are:</p>
  <ol>
  <li>System.*</li>
  <li>Microsoft.*</li>
  <li>AWSSDK.*</li>
  <li>Npgsql.dll</li>
  <li>Newtonsoft.Json.dll</li>
  <li>Some other dlls from other vendors</li>
  </ol>
  <p>(The list of DLLs is actually too long to be attached in this post without making it too long.)</p>
  <h3>Requirement</h3>
  <p>I require 64-bit version DLLs only and at the moment, I only have 32-bit version DLLs in our hand.</p>
  <h3>Things that I have tried</h3>
  <p>I verified the DLLs' version using a tool named SigCheck.</p>
  <p>I tried to find/convert the DLL version using the following methods:</p>
  <ol>
  <li>I searched on the internet and NuGet Package Manager but, I was not able to find 64-bit DLLs.</li>
  <li>I tried recompiling the project to 64 bit by changing below setting under project properties:
  <em>- Build -&gt; Platform Target -&gt; x64</em></li>
  </ol>
  <p>After compilation, the project DLL got converted to 64-bit. However, the remaining project DLLs' version didn't change.</p>
  <h3>Question</h3>
  <p>I would be grateful if someone could share documentation links/steps to convert 32-bit version DLLs to a 64-bit version?</p>
  <p>or</p>
  <p>Could someone please send us a link to find recompiled 64-bit version of the given DLLs?</p>
  <p>Please note that I'm using .NET framework 4.6</p>
