title: multiple .net core SDK (of different versions) installed, can I just keep the latest?
body: <p>I've been using Visual Studio Community IDE to develop some apps lately, and I just saw multiple .NET Core SDK with slightly different minor version updates installed on my desktop. (possibly installed along with the VS updates pushed by Microsoft)</p>
  
  <p>Question:
  <strong>can I just keep the latest version? (e.g. 2.1.103 in the case).</strong> </p>
  
  <p>or I have to keep all these versions (~460MB each in size) to keep the Visual Studio working, which is insane considering that my SSD is running out of free space (eventually)...</p>
