LLBLGen Pro QuerySpec: the basics
Last time I introduced LLBLGen Pro QuerySpec, a new fluent API for specifying queries for LLBLGen Pro. As promised I'll write a couple of blogposts about certain aspects of the new API and how it works. Today I'll kick off with the basics.

Introducing LLBLGen Pro QuerySpec: a new fluent query API
In the past two months I've been busy creating a new query specification API for LLBLGen Pro. Our native query API is modeled after SQL statement fragments (like a 'predicate', a 'relationship', a 'field'), but specifying a query with it can be a little verbose, and above all: the code doesn't look like a query. Especially with complex queries and projections it can sometimes be tedious to grasp what the SQL will look like and what the query is doing. With LLBLGen Pro QuerySpec this changes: a fluent, compact, highly expressive API which allows you to write queries in the structure of the SQL it will produce and with the expressiveness of Linq.

How to find and fix performance problems in ORM powered applications
Once in a while we get requests about how to fix performance problems with our framework. As it comes down to following the same steps and looking into the same things every single time, I decided to write a blogpost about it instead, so more people can learn from this and solve performance problems in their O/R mapper powered applications. In some parts it's focused on LLBLGen Pro but it's also usable for other O/R mapping frameworks, as the vast majority of performance problems in O/R mapper powered applications are not specific for a certain O/R mapper framework.
