Hey

I have a problem with my LINQ to Entity model many to mant relation. I am new to both C# and LINQ, so bear with me.

I have a model containing pictures and tags, where each picture can have many tags, and each tag can be on many pictures. In the db there is a normal relation table, but in the object model I see it as picture.tags (as a list) and tag.pictures (as a list). A search query contains several tags, and the result of the search is to contain all pictures that are tagged with all the tags (but maybe more) I have searched for. The number of tags to search for is not fixed.

How can this best be done?

The dynamic type in C# 4.0 is a welcome addition to the language.
