what is Error (CS1752 Interop type 'PointClass' cannot be embedded. Use the applicable interface instead.)

I am trying to update my Addin from ArcObject 10.3 to 10.5 using VS2015 .net 5.2 Frame work but I am getting Error

CS1752: CS1752 Interop type 'PointClass' cannot be embedded. Use the applicable interface instead.)

 // Get selected line segments end points
 pPolyline = pFeature.Shape as IPolyline;
 IPoint pOutPoint = new PointClass();
 // Convert screen coordinates to Map coordinates
 //pPoint = ;
 pMxApp = pApp as IMxApplication;
 pPoint = pMxApp.Display.DisplayTransformation.ToMapPoint(X, Y);  ‍‍‍‍‍‍‍

and same Error here as Well.

//Get normal
 ILine pTangent = new LineClass();
 pPolyline.QueryTangent(esriSegmentExtension.esriExtendTangentAtFrom, FromDist, false, 100.0, pTangent);‍‍‍

I do appreciate any help or hint

Check that Embed Interop Types is set to False for your ESRI assembly references. Its set to True by default when you add them in VS.

Thank you Sean, I found that just Removing the suffix Class solve the Problem..

// Get selected line segments end points
 pPolyline = pFeature.Shape as IPolyline;
 IPoint pOutPoint = new Point();
 // Convert screen coordinates to Map coordinates
 //pPoint = ;
 pMxApp = pApp as IMxApplication;
 pPoint = pMxApp.Display.DisplayTransformation.ToMapPoint(X, Y);

//Get normal
 ILine pTangent = new Line();
 pPolyline.QueryTangent(esriSegmentExtension.esriExtendTangentAtFrom, FromDist, false, 100.0, pTangent);
