I'm trying to generate map shapes in WKB format as shown in the example "WktReader". The only difference i made is to change the geospatial property string Geometry to byte array in order to store the wkb data which comes from database. When i run the program nothing shows up in the map. What else should i do in order to make it work, am i missing something??

Hello Dilsah,
It is very complicated and it is hard to reproduce the problem without your solution or code. Probably the problem is in a conversion data to WKB format.
When the SqlGeospatialDataReader.GeospatialPropertyName property specifies a property which represents Geospatial data in a the binary type (byte[]), then it will be read as Wkb. I have attached a sample solution which uses Geospatial data in the WKB format.
Note, that the 'StateCountiesWKB' view which is used in the database model uses the Geometry.STAsBinary() function of MSSQL to get the Geometry field in WKB format.
I hope it helps.
