Just found this interesting article:

Heartysoft.com | Anonymous Types are Internal, C# 4.0 Dynamic Beware!

That explained why my spark templates where failing at runtime because the default dynamic object only works for public and non-internal members.

I implemented the following class in order to use dynamic and non-dynamic models in our spark templates that are used in standalone mode for emailing templating:

public class DynamicViewData : DynamicObject

{

private readonly object _model;

public DynamicViewData(object model)

{

_model = model;

}

public override bool TryGetMember(GetMemberBinder binder, out object result)

{

var member = _model.GetType().GetMember(binder.Name,

BindingFlags.Instance |

BindingFlags.Public |

BindingFlags.NonPublic).FirstOrDefault();

if (member != null)

{

switch (member.MemberType)

{

case MemberTypes.Field:

result = ((FieldInfo)member).GetValue(_model);

return true;

case MemberTypes.Property:

result = ((PropertyInfo)member).GetValue(_model, null);

return true;

}

}

return base.TryGetMember(binder, out result);

}

}

And a custom AbstractSparkView which has a dynamic property where I'm passing an instance of this class together with the anonymous model.

Now I don't have to define in my spark templates the model type, and also I don't have to define in my code every single viewmodel.
