These idiots have no idea what they're doing. It's posted all over their website that they support ASP.NET 3.5. Which one would suppose means that they support LINQ too. But apparently thier server guys have never read the .NET readme. Which states (in section 2.3.1.4) that they need to modify the configuration for Medium Trust to allow the LINQ ...

Hi,Thank you very much for reporting the issue.Current implementation (in SVN) improved this time to something around 6 seconds (running on an emulator; running in an actual device should be faster)Note that the first time a Linq query is executed various assemblies must be loaded from the disk (flash memory); also, device cpus are slower than a ...

After the introduction of an ...

Db4o for .NET 3.5 ships with an optimizing LINQ provider. This provider is able to optimize the execution of a query by analyzing the LINQ expression tree emitted by the C# (or VB.NET) compiler to produce an equivalent SODA query which can be executed by db4o at full speed.The Compact Framework 3.5 however includes no support for expression trees. ...

So i've been doing some work with LINQ in one of my projects and I ran into a few difficulties. After a few postins in the MSDN support newsgroups, this is what we've come to. I almost had to rip out all the LINQ code I'd written, but instead we've gone into our application with a chainsaw and had to GREATLY simplify the entire application arround ...

One of the key ideas behind db4o is that it should integrate as tightly as possible with the programming language. We are not trying to invent new concepts or new theories, we simply use the ones that are already there, in your programming language. The elegance of what we can deliver varies with what the programming language provides us with. On ...

Here are latest thoughts on LINQ for Java and a newly registered domain for an open source initiative, for now pointing to a dedicated Google group: LINQ for Java http://www.jlinq.org

LINQ - Language INtegrated Queries - are a developers dream come true. Queries are an integral part of the primary programming language. They are typesafe, compile-time checked, refactorable and autocompleted by the IDE. If you want to read up more on LINQ, Charlie Calvert’s Links to LINQ are a nice starting point. At db4objects we really like ...

Dutch senior web developer Edwin Vermeer just published a demo web application on The Code Project for demonstrating the power of LINQ for db4o. In order to show the most basic operations the demo solution includes a very simple console application that creates 2 new objects and stores them in a db4o database. Before and after ...
