Use JOIN instead of LEFT JOIN for associations with non-nullable foreign key columns

Currently OpenAccess uses left joins to retrieve data from multiple related tables in a single query. It is more optimal to use inner joins when the foreign key column does not allow null values.

from product in context.Products
select new { product.ProductName, product.Category.CategoryName };

results in the following SQL statement:
SELECT a.[ProductName] AS COL1, b.[CategoryName] AS COL2 FROM [Products] a LEFT JOIN [Categories] AS b ON (a.[CategoryID] = b.[CategoryID])

but could be optimized as follows, if a.[CategoryID] is not a nullable column.:
SELECT a.[ProductName] AS COL1, b.[CategoryName] AS COL2 FROM [Products] a JOIN [Categories] AS b ON (a.[CategoryID] = b.[CategoryID])

Mono support

Hey guys,

Mono support would be nice - just for the fluent API.
See this post, it's from 2009 and nothing happened so far (

Out of the box asynchronous queries

As OpenAccess developer I would like to be able to queries against database in asynchronous manner. This will allow me to develop more responsive applications and improve performance in numeric scenarios.
Currently I have to implement asynchronous queries manually which is tedious and error prone work.

Generation of fluent models with Data Access Q2 2015 and higher

After the deprecation of the Visual Studio integration, the database-first approach of building Data Access models is not supported, and a tool that provides it will be handy.
