EF4 LINQ Include(string) alternative to hard-coded string?

Question

Is there any alternative to this:

Organizations.Include(\"Assets\").Where(o => o.Id == id).Single()

I would like to see something like:<

Another option is to include an internal partial class inside your class using the TT template.

T4 code:

<#
    region.Begin("Member Constants");
#>
   public partial class <#=code.Escape(entity)#>Members
   {
<#
    foreach (EdmProperty edmProperty in entity.Properties.Where(p => p.TypeUsage.EdmType is PrimitiveType && p.DeclaringType == entity))
    {
        bool isForeignKey = entity.NavigationProperties.Any(np=>np.GetDependentProperties().Contains(edmProperty));
        bool isDefaultValueDefinedInModel = (edmProperty.DefaultValue != null);
        bool generateAutomaticProperty = false;
        #>
        public const string <#=code.Escape(edmProperty)#> = "<#=code.Escape(edmProperty)#>";
        <#
    }
    #>
    }
    <#
    region.End();
#>

Which will produce something like:

    #region Member Constants
   public partial class ContactMembers
   {
        public const string ID = "ID";
                public const string OriginalSourceID = "OriginalSourceID";
                public const string EnabledInd = "EnabledInd";
                public const string EffectiveDTM = "EffectiveDTM";
                public const string EndDTM = "EndDTM";
                public const string EnterDTM = "EnterDTM";
                public const string EnterUserID = "EnterUserID";
                public const string LastChgDTM = "LastChgDTM";
                public const string LastChgUserID = "LastChgUserID";
            }

    #endregion
