Just a quick follow-up that may elaborate more fully for the archives:
AppDomain.CreateInstance returns a System.Remoting.ObjectHandle. In
order to get at the object created, you need to use
CreateInstanceAndUnwrap. Here is the code I wrote that uses it:
public static IGroupOneSetting GetSetting(XmlNode settingNode)
{
string typeName = settingNode.Attributes["type"].Value;
string typeAssembly;
if(settingNode.Attributes["assembly"] == null)
{
typeAssembly = "GroupOne.Goat.Comet";
}
else
{
typeAssembly = settingNode.Attributes["assembly"].Value;
}
AppDomain thisDomain = AppDomain.CurrentDomain;
object theSettingObject =
thisDomain.CreateInstanceAndUnwrap(typeAssembly, typeName);
IGroupOneSetting theSetting =
(IGroupOneSetting)theSettingObject;
theSetting.Deserialize(settingNode);
return theSetting;
}
Hopefully, this will save someone some time in the future.

All--
I'm sure I've seen this somewhere before, but can't find it now. If I
have the name of a type as a string (ie "System.Text.StringBuilder," how
do I use it to construct an instance of that type?
TIA
