title: Visual Studio 2019 Data Sources not available
body: <p>I installed Visual Studio a few weeks.<br />
  Now I want to connect a Microsoft SQL table to my windows form project in C#.</p>
  <p>Therefore I want to use the data source window.
  But this window shows a problem.</p>
  <p>Please have a look at my screenshot.</p>
  <p>I installed Visual Studio already a second time.</p>
  <blockquote>
  <p>this window is not supported for the selected project. Steps to activate data binding can be found here.</p>
