I have Thinkgeo’s MapSuite Version 9.0 to work on MvcEdition. I want to add shapefile over google map.  
but m getting this  
Could not load type ‘GisSharpBlog.NetTopologySuite.Index.Quadtree.Quadtree’ from assembly ‘NetTopologySuite, Version=1.14.0.0, Culture=neutral, PublicKeyToken=f580a05016ebada1’  
exception for below line  
FeatureLayer layer = new ShapeFileFeatureLayer(Server.MapPath(“filePath”));

I am unable to proceed further

Thanks,  
djay

Hi Djay,

Please try our latest V10, some known issue on V9 should get fixed in the new version.

And for your problem I guess that’s related with environment, you can build a simple sample and let us test that to make sure it. And you can reinstall our product to see whether it can be fixed.

Regards,

Ethan
