I have, and I think it is better. To be fair to #Copilot, I'm working in the #cslanet codebase, which is not trivial.

I do like how #copilot picks up the English language around #cslanet - like metastate properties and other CSLA jargon.

I suppose this is because CSLA has been #oss for 28 years and Copilot was trained on open-source code (including CSLA).

CSLA 2-tier Data Portal Behavior History The CSLA data portal originally treated 2- and 3-tier differently, primarily for performance reasons. Back in the early 2000’s, the data portal did not serialize the business object graph in 2-tier scenarios. That behavior still exists and can be enabled via configuration, but is not the default for the reasons discussed in this post. Passing the object graph by reference (instead of serializing it) does provide much better performance, but at the cost of being behaviorally/semantically different from 3-tier. In a 3-tier (or generally n-tier) deployment, there is at least one network hop between the client and any server, and the object graph _must be serialized_ to cross that network boundary. When different 2-tier and 3-tier behaviors existed, a lot of people did their dev work in 2-tier and then tried to switch to 3-tier. Usually they’d discover all sorts of issues in their code, because they were counting on the logical client and server using the same reference to the object graph. A variety of issues are solved by serializing the graph even in 2-tier scenarios, including: 1. Consistency with 3-tier deployment (enabling location transparency in code) 2. Preventing data binding from reacting to changes to the object graph on the logical server (nasty performance and other issues would occur) 3. Ensuring that a failure on the logical server (especially part-way through the graph) leaves the graph on the logical client in a stable/known state There are other issues as well - and ultimately those issues drove the decision (I want to say around 2006 or 2007?) to default to serializing the object graph even in 2-tier scenarios. There is a performance cost to that serialization, but having _all_ n-tier scenarios enjoy the same semamantic behaviors has eliminated so many issues and support questions on the forums that I regret nothing.

Some #cslanet #dotnet history

Just merged what may be the largest PR in #cslanet history - Stephan added NRT support throughout much of the codebase!

Obviously this is a breaking change, and so will be part of version 10.

It is also a big improvement to the code.

We've pushed #cslanet version 7.0.7. Normally v7 would be too old for such a thing, but it is the last version that supports #xamarin and a community member submitted a fix to an issue that was blocking them from working, so it seemed wise to do the update.

We're excited to share that #cslanet version 9.0.0 is online!

This is a big release, though with limited breaking changes. Tons of enhancements, optimizations, and bug fixes. And the most contributors of any release to date

#cslanet 9 release candidate 3 is now online.

github.com/MarimerLLC/c...

So close to a #cslanet v9 release - except it turns out that the #dotnet #aot stuff required by #dotnetmaui now has quite the cascade effect in the code, so we're working through those issues before releasing 9.0. Some of the fixes may require subtle breaking changes.

I am sometimes reminded just how great it is to work on #oss projects like #cslanet and #kidsidkit.

People occasionally submit PRs out of the blue to fix bugs or backport massive changes to a previous version because they can't upgrade and need a feature.

So cool, and I am so happy!
