In the announcement for the Wolverine 5.0 release last week, I left out a pretty big set of improvements for modular monolith support, specifically in how Wolverine can now work with multiple databases from one service process. Wolverine works closely with databases for: And all of those features are supported for Marten, EF Core with … Continue reading Wolverine 5 and Modular Monoliths→| The Shade Tree Developer
The Wolverine 5.0 release earlier last last week (finally) added a long requested SignalR transport. The SignalR library from Microsoft isn’t hard to use from Wolverine for simplistic WebSockets or Server Sent Events usage as it was, but what if you want a server side application to exchange any number of different messages between a browser (or … Continue reading Using SignalR with Wolverine 5.0→| The Shade Tree Developer
That’s of course supposed to be a 1992 Ford Mustang GT with the 5.0L V8 that high school age me thought was the coolest car I could imagine ever owning (I most certainly never did of course).

Until today’s Marten 8.12 release, Marten’s Async Daemon and a great deal of Wolverine‘s internals were both built around the venerable TPL DataFlow library. I had long considered a move to the newer System.Threading.Channels library, but put that off for the previous round of major releases because there was just so much other work to … Continue reading Marten 8.12 with New Plumbing→| The Shade Tree Developer
To the best of my recollection and internet sleuthing today, development on Marten started in October of 2015 after my then colleague Corey Kaylor had kicked around an idea the previous summer to utilize the new JSONB feature in PostgreSQL 9.4 as a way to replace our then problematic usage of a third party NoSQL … Continue reading Celebrating Marten’s 10th Birthday!→| The Shade Tree Developer
A JasperFx Software client was asking recently about the features for software controlled load balancing and “sticky” agents I’m describing in this post. Since these features are both critical for Wolverine functionality and maybe not perfectly documented already, it’s a great topic for a new blog post! Both because it’s helpful to understand what’s going … Continue reading Leader Election and Virtual Actors in Wolverine→| The Shade Tree Developer
Little update since the last check in on Wolverine 5.0. I think right now that Wolverine 5.0 hits by next Monday (October 6th). To be honest, besides documentation updates, the biggest work is just pushing more on the CritterWatch backend this week to see if that forces any breaking changes in the Wolverine internals. What’s … Continue reading Last Sprint to Wolverine 5.0→| The Shade Tree Developer

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
