Entity Framework LINQIf you’re doing Model First with Entity Framework you may run into a scenario where you want to design a 1-to-1 relationship, but also have a foreign key be available on your entity. The default behavior in Entity Framework when doing a 1-to-1 relationship (with Model First), or 1-to-0.1 relationship, is to create a foreign key on the 0.1 side of the association but hide the foreign key. better approach is this: Start a new model. Add the entity that goes on the 1 side of the association, give it a primary key of type integer. Add the entity that goes on the 0.1 DevelopMentor Courses - Wednesday, June 29, 2011 - Logging and tracing with Entity Framework

must have for people using LINQ to SQL and Entity Framwork. Helps a lot with figuring out what the exact SQL statement is that get generated from your LINQ statement. Last night at the BAND ( www.bangordevelopers.com ) meeting we all did 10 minute presentations on the tool(s) we love as developers. On my list were: Total Commander, LinqPad, Microsoft Office (codegen with Excel rules :-)), VMWare & VirtualPC, Live Mesh. Also on the list should have been Reflector. Total Commander. Also much more reliable in FTP-ing large amounts of files than Windows Explorer. LinqPad. Love it! The Blomsma Code - Wednesday, August 26, 2009 %>

'[ Note : I am reblogging this post which originally was posted to the LearningLine blog. Hope you all find it useful here as well]. recently had a conversation with someone who is looking to make a fresh start and become a developer (coming from other IT positions). The question they had was: What should I learn to get started in.NET and web development? Now this question was starting from a position of “I’d like to get started with.NET and the web. How do I do that?” That’s another blog post. :). jQuery basics. Michael C.

'This article demonstrates a technique and supporting library for adding optimistic concurrency control to NoSQL databases and MongoDB in particular. Quickly, what is optimistic concurrency control? Ideally, all databases that allow concurrent access or disconnected access need to implement some form of concurrency control. This usually comes in two flavors: Pessimistic concurrency control. Optimistic concurrency control. Pessimistic concurrency control is usually used when working heavily within transactions. Edit in memory. Michael C. Kennedy's Weblog - Monday, April 8, 2013 | -

Interact with the database using LINQ. Shortly we’ll look at an example where we build out a disconnected, offline RSS reader that uses MongoDB and LINQ to store its data. You have several options when choosing how to access MongoDB from.NET but generally that means using LINQ and a light-weight object-mapper on top of MongoDB itself. Then we’d use LINQ to SQL or Entity Framework to generate the ORM classes. We begin by generating the objects (Blog, RssEntry, etc) in memory and then serializing them via NoRM to MongoDB much as you would in LINQ to SQL. Ok, ok. Michael C.
