  foreach (MountPointScanSource source in sourceList.Where(x => !x.AnythingFound))

• we are looking for dlls only with specific filenames (should contain netcoreapp, netstandard, net4)
  

  templating/src/Microsoft.TemplateEngine.Edge/AssemblyLoadContextHelper.cs

  Line 38 in 65f6271

  if(file.IndexOf("netcoreapp", StringComparison.OrdinalIgnoreCase) > -1 || file.IndexOf("netstandard", StringComparison.OrdinalIgnoreCase) > -1)

• we are treating components as found even if there are no components loaded
