bizarre NullLogger behaviour

i was using NullLogger in orchard and I needed to do this

    public MenuProvider(UrlHelper urlHelper, IOrchardServices services)

              {

                     _urlHelper = urlHelper;

                     _services = services;

            Logger = NullLogger.Instance;

              }

instead of just referring to NullLogger.Instance.Log("blah")

View dependencies

in ssms is not always correct because it depends on sysdepends



this is more accurate

select t.name as TableWithForeignKey, fk.constraint_column_id as FK_PartNo , c.name as ForeignKeyColumn
from sys.foreign_key_columns as fk
inner join sys.tables as t on fk.parent_object_id = t.object_id
inner join sys.columns as c on fk.parent_object_id = c.object_id and fk.parent_column_id = c.column_id
where fk.referenced_object_id = (select object_id from sys.tables where name = 'BLAH')
order by TableWithForeignKey, FK_PartNo

cache: false in $.ajax( calls

work because they add the following request header

1. Cache-Control:
   no-cache

De-serialization issue checklist

make sure

1) all base classes and properties are properly adorned

          [DataContract]

          [Serializable]

2) base class and property may need also knowntype

       [KnownType(typeof(BlahBase))]

        public class Blah: BlahBase

in order to get type name from collection

 typeof(T).FullName.Between(


the between is an extension i found here 

for Serialization with distributed caching

 [DataContract]

was not enough

i needed

[Serializable]
