Hello,

I decided to switch my C# application to 64-bit, but I’m having a problem with the method:

ImportFromESRI ();

The application closes, without any error message.

> string proj = “GEOGCS["GCS\_WGS\_1984",DATUM["D\_WGS\_1984",SPHEROID["WGS\_1984",6378137,298.257223563]],PRIMEM["Greenwich",0],UNIT["Degree",0.017453292519943295]]”;
> 
> GeoProjection g = new GeoProjection();
> 
> g.ImportFromESRI(proj); // Crash!

Do you have an idea of ​​the problem ?

Thanks for your help,

Sorry I didn’t have time to test it. I’ll try to do that this week.

I can reproduce the crash when in x64 mode.  
I’ve created [[MWGIS-271] GeoProjection.ImportFromESRI() crashes on x64 build](https://mapwindow.atlassian.net/browse/MWGIS-271)

I will have a look at it.
