Ok, I have tried to build the examples on two development machine and I get this error on both.
Error 1 'Esri.FileGDB.Row' does not contain a definition for 'Geometry' and no extension method 'Geometry' accepting a first argument of type 'Esri.FileGDB.Row' could be found (are you missing a using directive or an assembly reference?) C:\FileGDB_API_VS2010_1_1\samplesC#\Display\Form1.cs 115 43 Display
Am I missing something? I installed OpenTK to overcome that error. I have tried compiling as x86 and x64. Same errors.
The systems are both using VS2010 and the operating systems are Windows XP Version 2002 SP3 (32-bit) and Windows Server 2008 R2 Datacenter Service Pack 1 (64-bit).
