title: HashCode equivalent in .Net Framework
body: <p>In converting .NET Core project to .NET Framework, one thing notice is using Hashcode now needs to be converted something equivalent. As can be read, Hashcode is specific to .NET core versions and some extensions.</p>
  
  <pre><code>https://docs.microsoft.com/en-us/dotnet/api/system.hashcode?view=dotnet-plat-ext-3.1
  </code></pre>
  
  <p>Wonder what would be close enough in terms of usages in .NET Framework, if there is any in-built object type.</p>
