HOW TO CREATE SPFieldLookup programmatically

This is a nice snippet I saw and will like to share

Let us assume we have two list aList and bList already created.

Requirement is to create a lookup column in aList which will look up values in bList.

SPList aList = web.Lists["aList"];
SPList bList = web.Lists["bList"];

aList.Fields.AddLookup("Lookup", bList.ID, false);
SPFieldLookup fldLookup = aList.Fields["Lookup"] as SPFieldLookup;

fldLookup.LookupField = bList.Fields[SPBuiltInFieldId.Title].InternalName;
fldLookup.Update();

PublishingAssociatedContentType

The Content Type to be associated with a page layout is indicated by the 'PublishingAssociatedContentType'. In the actual sense it means a binding setting between the Page Layout and the content type. If you fail to provide one, the SharePoint framework will make use of the Page Content type. The format of the binding is: ';# e.g. ';#ContentPage;#0x010100C568DB52D9D0A14D9B2FDCC96666E9F2007948130EC3DB064584E219954237AF3900470b13dd348649d08f9e5151501df9a4000dbd46dad8d045f98c83ad983b66d3f2;#'. where Content Type name: ContentPage Content Type ID: 0x010100C568DB52D9D0A14D9B2FDCC96666E9F2007948130EC3DB064584E219954237AF3900470b13dd348649d08f9e5151501df9a4000dbd46dad8d045f98c83ad983b66d3f2 respectively.
