  I create a simple table in SqlServer .. key field integer, 4 strings and a Timestamp This Table is called Event .. which pluralizes to Events.(the checkbox was ticked) I run the Entity Builder in VS2010 just adding this table only. EntityModelXXX x = new EntityModelXXX(); // create an object 'e' here x.AddToEvents(e); produces an error : The EntitySet name 'EntityModelXXX.Events' could not be found.

• Entity Framework - avoiding another query

  - by adamjellyit

  I have a requirement to only save data to a table in a database (I don't need to read it) If the record already exists I want to update it otherwise I will add it. It usually exists. My entity context might already hold the object .. if it does I want to find it and use it again without causing it to refresh from the database when I 'find' it i.e. The context holds a collection of entities (rows of a database) I want to find an entity in the collection and only want the context to go to the database if entity is not in the collection. I don't care about the current values of the entity .. I just want to update them. Hope this is clear ..... thanks

• Threading and iterating through changing collections

  - by adamjellyit

  In C# (console app) I want to hold a collection of objects. All objects are of same type. I want to iterate through the collection calling a method on each object. And then repeat the process continuously. However during iteration objects can be added or removed from the list. (The objects themselves will not be destroyed .. just removed from the list). Not sure what would happen with a foreach loop .. or other similar method. This has to have been done 1000 times before .. can you recommend a solid approach?
