title: SqlGeometry in C++ Application?
body: <p>I've used Microsoft's <code>SqlGeometry</code> from <a href="https://msdn.microsoft.com/de-de/library/microsoft.sqlserver.types.aspx" rel="nofollow noreferrer"><em>Microsoft.SqlServer.Types</em></a> in a C# application and was quite happy with the performance. I saw that it's actual functionality is contained in a native library, <em>SqlServerSpatial110.dll</em> (or another number, depending on the SqlServer version it belongs to), since this DLL exposes the common geometry functions like <code>Overlaps</code>, <code>Centroid</code>, <code>Buffer</code> etc.</p>
  
  <p>Is there any chance that I could use that DLL from a <strong>C++</strong> application <em>directly</em>, i.e. without going through a managed wrapper (e.g. C++/CLI)? Is there a header file and a lib somewhere that I could use, and maybe some documentation?</p>
