title: NuGet: How to increment nuget package version when any file in the solution changes?
body: <p>I have a NuGet nuspec file responsible for creating a NuGet package from HelloWorld.Main.dll
  and the package version is incremented each time I make a change in HelloWorld.Main project.</p>
  
  <p>What if I want to get the version incremented whenever I make a change to any other project in my solution.</p>
  
  <pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt;
       &lt;package xmlns="http://schemas.microsoft.com/packaging/2011/08/nuspec.xsd"&gt;
       &lt;metadata&gt;
           &lt;id&gt;HelloWorld.Main&lt;/id&gt;
           &lt;version&gt;$version$&lt;/version&gt;
           &lt;title&gt;$title$&lt;/title&gt;
           &lt;authors&gt;$author$&lt;/authors&gt;
           &lt;owners&gt;$author$&lt;/owners&gt;
           &lt;requireLicenseAcceptance&gt;false&lt;/requireLicenseAcceptance&gt;
           &lt;description&gt;$description$&lt;/description&gt;

           &lt;dependencies&gt;
           &lt;dependency id="HelloWorld.Helpers" version="[0.0.7,0.1)" /&gt;
           &lt;/dependencies&gt;
       &lt;/metadata&gt;
