For any shops using the “Critter Stack” (Marten and Wolverine), JasperFx Software offers support contracts and custom consulting engagements in support of these tools — or really anything you might be doing on the server side with .NET as well. Something we’ve had some success with, especially lately, is positioning these “support” contracts as essentially … Continue reading Little Diary of How JasperFx Helps Our Clients→| The Shade Tree Developer
We’re targeting October 1st for the release of Wolverine 5.0. At this point, I think I’d like to say that we’re not going to be adding any new features to Wolverine 4.* except for JasperFx Software client needs. And also, not that I have any pride about this, I don’t think we’re going to address … Continue reading Update on Wolverine 5 and CritterWatch→| The Shade Tree Developer
So here’s a common scenario when building a system using Event Sourcing with Marten: As an example, let’s say that your application has some reference information about system users saved in this document type (from the Marten testing suite): And you also have events for some kind of UserTask aggregate that manages the workflow of … Continue reading Event Enrichment in Marten Projections→| The Shade Tree Developer

Earlier this week I did a live stream on the upcoming Wolverine 5.0 release where I just lightly touched on the concept for our planned SignalR integration with Wolverine.

I’ll be doing a live stream tomorrow (Thursday) August 4th to preview some of the new improvements coming soon with Wolverine 5.0. The highlights are: And of course anything else folks want to discuss on the live stream as well. Check it out here, and the recording will be up later tomorrow anyway:| The Shade Tree Developer
A couple weeks back I posted about some upcoming feature work in Wolverine that might push us to call it “5.0” even though Wolverine 4.0 is only three months old. Despite the obvious issues with quickly cranking out yet another major point release, the core team & I mostly came down on the side of … Continue reading Update on Wolverine 5.0 Work→| The Shade Tree Developer
I just pulled the trigger on Marten 8.8 and Wolverine 4.10 earlier today. Neither is particularly large, but there’s some new toys and an important improvement for test automation support tha…| The Shade Tree Developer

Let’s just say that Marten incurs some serious benefits to being on top of PostgreSQL and its very strong support for transactional integrity as opposed to some of the high profile commercial Event Sourcing tools who are spending a lot of time and energy on their “Dynamic Consistency Boundary” concept because they lack the ACID … Continue reading Operations that Span Multiple Event Streams with the Critter Stack→| The Shade Tree Developer
