title: JetBrains Rider targets 4.5 framework and no option to switch to 4.7
body: <p>Basically, when trying to add NuGet package which is not supporting older frameworks getting the error.</p>
  
  <p>However in project configuration only 4.5 is available.</p>
  
  <p>During the project creation no option to select the target is present.</p>
  
  <p>Is there any way to configure it properly?</p>
