Map Multilist field with objects of different templates

I have a multilist field on an item that can contain items from different templates. I was wondering if there was any way to map this field in such a way that the objects are mapped to the correct model based on their template. So for example:

public interface IPerson
{
    string FullName {get; set;}
}

[SitecoreType(TemplateId="....")]
public class Professor
{
    [SitecoreField]
    public string Prefix {get; set;}
    [SitecoreField]
    public string FirstName {get; set;}
    [SitecoreField]
    public string LastName {get; set;}

    public string FullName
    {
        return string.format("{0} {1} {2}", Prefix, FirstName, LastName)
    }
}

[SitecoreType(TemplateId="....")]
public class Student
{
    [SitecoreField]
    public string FirstName {get; set;}
    [SitecoreField]
    public string LastName {get; set;}

    public string FullName
    {
        return string.format("{0} {1}", FirstName, LastName)
    }
}

[SitecoreType(TemplateId="....")]
public class ClassSession
{
    [SitecoreField]
    public IEnumerable<IPerson> Participants {get; set;}
}

In this instance I'd like the Participants property to contain Student and Professor objects since they implement the Fullname property differently.

You can use infer types in Glass.mapper, Inferred types allows you to load a more specific type based on the template of the item being loaded. :

public interface IPerson
{
    string FullName {get; set;}
}

[SitecoreType(TemplateId="....", AutoMap = true)]
public class Professor : IPerson
{
    [SitecoreField]
    public string Prefix {get; set;}
    [SitecoreField]
    public string FirstName {get; set;}
    [SitecoreField]
    public string LastName {get; set;}

    public string FullName
    {
        return string.format("{0} {1} {2}", Prefix, FirstName, LastName)
    }
}

[SitecoreType(TemplateId="....", AutoMap = true)]
public class Student : IPerson
{
    [SitecoreField]
    public string FirstName {get; set;}
    [SitecoreField]
    public string LastName {get; set;}

    public string FullName
    {
        return string.format("{0} {1}", FirstName, LastName)
    }
}

[SitecoreType(TemplateId="....", AutoMap = true)]
public class ClassSession
{
    [SitecoreField(Setting = SitecoreFieldSettings.InferType)]
    public IEnumerable<IPerson> Participants {get; set;}
}

Notice that i added AutoMap = true in your classes atrributes, and changed your multilist property attribute to be like:

[SitecoreField(Setting = SitecoreFieldSettings.InferType)]

For more details, go to mike tutorials here: http://glass.lu/docs/tutorial/sitecore/tutorial17/tutorial17.html

Edit:

You need to include your assembly in configurations loader, find the GlassMapperScCustom class in your solution. You should then update the GlassLoaders method:

public static IConfigurationLoader[] GlassLoaders()
    {
        var attributes = new AttributeConfigurationLoader("Your assembly name");

        return new IConfigurationLoader[] {attributes };
    }
