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

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);

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.
