The usual cause for this is that one of the GDAL DLLs that you need is 
not being found at runtime. If you look at the inner exception details 
you may see a message about DLLs.

The gdal_csharp.dll assembly you added a reference to in your project is 
merely a front for gdal_wrap.dll, which in turn calls gdal14.dll to do 
the work.

You need to make sure that the GDAL DLL  and the "wrap" DLLs are in a 
place that they can be found at runtime. This usually means they either 
have to be in the same directory as your applications, or in a directory 
that is listed in your PATH. Note that this is all in addition to adding 
a reference to the GDAL C# assemblies.
