Fabio Maulo closed NH-2637.
---------------------------

    Resolution: Not an Issue

It is by design because properties and fields are case-sensitive in .NET and if you have a property called "FirstName" with a field called "firstName" the default transformer have to know to which one it have to access. 
You can specify the alias in your query or you can implement your AliasToEntityResultTransformer.

> We are running NH 2.1 and discovered this bug trying to upgrade to NH 3.1. We do a lot of AliasToBean stuff, mapping tables to DTOs, and AliasToBean will call this method to get the properties. Problem is, it's case sensitive now! Reading code comments i see this:
> ============ <CODE SNIPPET> ================
> 			BindingFlags bindingFlags = BindingFlags.Instance | BindingFlags.Public | BindingFlags.NonPublic | BindingFlags.DeclaredOnly;
> 			if (type.IsValueType)
> 			{
> 				// the BindingFlags.IgnoreCase is important here because if type is a struct, the GetProperty method does
> 				// not ignore case by default. If type is a class, it _does_ ignore case... we're better off explicitly
> 				// stating that casing should be ignored so we get the same behavior for both structs and classes
> 				bindingFlags = bindingFlags | BindingFlags.IgnoreCase;
> 			}
> ============ </CODE SNIPPET> ================
> "If type is a class, it _does_ ignore case..." -- incorrect. By default in classes case will _not_ be ignored, you explicitly have to specify it using a flag, same as you do for value type.
> The fix for this is rather simple, just add the BindingFlags.IgnoreCase flag and all's good. No need for the "if (type.IsValueType)" anymore either. GetGetterOrNull suffers from the same.
> Thank You!!!
