Initializing Core Host

The main entry point for the application, responsible for initializing the ArcGIS Core Host.

[STAThread]

{
  //Call Host.Initialize before constructing any objects from ArcGIS.Core
  try
  {
    Host.Initialize();
  }
  catch (Exception e)
  {
    // Error (missing installation, no license, 64 bit mismatch, etc.)
    Console.WriteLine(string.Format("Initialization failed: {0}", e.Message));
    return;
  }

  //if we are here, ArcGIS.Core is successfully initialized
  Geodatabase gdb = new(new FileGeodatabaseConnectionPath(new Uri(@"C:\Data\SDK\GDB\MySampleData.gdb")));
  IReadOnlyList<TableDefinition> definitions = gdb.GetDefinitions<FeatureClassDefinition>();

  foreach (var fdsDef in definitions)

  }
  Console.Read();
}
