I can now get the Raster Layers working fine with your patch... however when I try to use MapInfo TAB files and the OGR provider I get the following error
"Error 1 '.ctor' is ambiguous because multiple kinds of members with this name exist in class 'SharpMap.Data.Providers.Ogr'. C:\Liverpool\WindowsApplication1\WindowsApplication1\Form1.vb
8 37 "
The code that seems to mess up is... (VB.NET Express 2008 version)
MyMapInfoLayer.DataSource = New SharpMap.Data.Providers.Ogr("MyMapinfoTABFile.TAB")
I have the GDAL unmanaged DLLs in the bin\debug folder including the "*wrap.DLLs" too.
Any additional help greatfully received.
