F# and ArcObjects, Part 1

After having a first look on F# its time to ask: How could i use F# with ArcObjects.

So my first steps was to do something with a feature in a F# interactive session. And these are my first code lines:

open System;;



#I "C:\Program Files\ArcGIS\DotNet";;

#r "ESRI.ArcGIS.System.dll";;

#r "ESRI.ArcGIS.DataSourcesGDB.dll";;

#r "ESRI.ArcGIS.Geodatabase.dll";;

open ESRI.ArcGIS.esriSystem;;

open ESRI.ArcGIS.DataSourcesGDB;;

open ESRI.ArcGIS.Geodatabase;;



let aoInitialize = new AoInitializeClass();;



let status = aoInitialize.Initialize(esriLicenseProductCode.esriLicenseProductCodeArcEditor);;



let workspacefactory = new SdeWorkspaceFactoryClass();;



let connection = "SERVER=okul;DATABASE=p;VERSION=sde.default;INSTANCE=sde:sqlserver:okul;USER=s;PASSWORD=g";;



let workspace = workspacefactory.OpenFromString(connection, 0);;



let featureWorkspace = (box workspace) :?> IFeatureWorkspace;;



let featureClass = featureWorkspace.OpenFeatureClass("Praxair.SFG.BP_L_ROHR");;



let feature = featureClass.GetFeature(100);;

printfn "%A" feature.OID;;
