title: Remove reference to csproj Visual Studio
body: <p>Hi I received a project and there is a reference that I need to remove, but when I right click on the reference name inside the Solution explorer the option <code>Remove</code> is not displayed, when I check the properties, this is the path: <code>C:\Users\User\Desktop\MyProject\MyClasses\ClassReferenced.csproj</code>
  This is an image of what I'm describing:</p>

  <p>How can I remove that reference? I'm using ASP.net Core pointing to the <code>.net</code> framework.</p>
  
  <p>The reference icon looks like this, it's different from the Nuget icon and from the system icons, it's referencing a csproj file(it's the one with blu color filled besides):
