Mastering Entity Framework Core workshop (discount inside) and .NET DeveloperDays 2024
We are couple of weeks from .NET DeveloperDays 2024. Really excited to be there. My main “show” there is going to be Mastering Entity Framework Core workshop.
We are couple of weeks from .NET DeveloperDays 2024. Really excited to be there. My main “show” there is going to be Mastering Entity Framework Core workshop.
Tento týden se koná, dneska už tradiční dvojboj konferencí, WUG Days 2024 a SQL Server Bootcamp 2024 v Brně. A tak jako obvykle, připravil jsem několik přednášek.
I’ll be speaking this Thursday about Tips and tricks for VS debugger in Vienna for DotNetDevs.at. You can register here.
One of my favourite conferences – .NET Developer Days – that happens in Warsaw in fall is now having also a Berlin edition. And I’m a big fan of Berliner Fernsehturm. Looks like a perfect combination (well, perfect combination would be to have the conference in Fernsehturm 😉). Anyway, I’ll have two sessions there and I hope to see you there.
I’m excited to announce the release of Entity Framework Core 8 provider for Firebird.
I was working on a codebase the other day and it used heavily the pattern matching features of C#. And as I was writing string.IsNullOrEmpty
it got me thinking whether I could switch from this very specific method to using (maybe) a more general pattern matching approach. And also, how that compares in performance.

2.5.2024 od 17:00 na WUGu v Olomouci si popovídáme o async a await. Přednáška Async a await pěkně od podlahy má v mém reportoáru už asi 30 podob. Pokaždé když ji dělám řeknu něco jinak, někdo se zeptá na něco zajímavého atp. a ani tady to nebude jinak. Tak se přijďte podívat a udělat se mnou další podobu.
Zítra, 19. dubna, se koná globalní akce Global Azure 2024. I já přispěju trochu do mlýna s tématem Azure Spot instances as your secret weapon.
16.4.2024 od 17:30 na WUGu ve Zlíně si dáme dvojpřednášku. Laďte jak profík ve Visual Studiu a Práce se stringy v .NET 8 a SearchValues.
I’ll be speaking at this years Warsaw IT Days 2023. One sessions What’s new in C# 12 will be in-person in Warsaw, while other Dynamic PGO in .NET 8 and why you need to know about it is VoD.
V pondělí se uskuteční WUG Dev Day 2024. Připravil jsem dvě přednášky.
My mind was wandering, as usual when it is not 100% occupied, and I remembered that the Select
LINQ function has an overload that gives you the index into the enumeration and it uses an int. So, I thought what’s going to happen if I have longer enumeration and it goes over the range of the int?
Step forward for FbNetExternalEngine today – version 6.0 is ready, you can go and download it right now.
New major version 10.0.0.0 of ADO.NET provider for Firebird is ready for download.
Trhák letošního roku – .NET 8 – 14.11. v premiéře ve Zlíně s celebritami. Řečeno normálně, společné sledování keynote .NET Conf 2023 v rámci WUGu ve Zlíně, následná diskuze s experty a také neformální hospoda. Lepší úterní večer asi těžko vymyslíte (nebo nejste opravdový geek 😄). Tak doufám, že se tam uvidíme.
Less than a week until .NET Developer Days 2023. Can’t wait to be there. This year, I’ll be doing workshop and session.
After the Belgium version Techorama is going to Netherlands, in October 9-11.
I’ll deliver workshop called Mastering Entity Framework Core – basically in something like 8 hours I’ll try to teach you Entity Framework Core all the way into “monk” level. It will be a lot of stuff, but also lot of fun.
Besides the workshop, I’ll also have two sessions Autoincrement (identity) is not the only option for primary keys and What’s new in Entity Framework Core 7 (abstracts below).
Pokud to nemáte do Olomouce daleko, můžeme se ve středu 27.9.2023 od 17:00 potkat na WUGu v Olomouci s tématem Na co mám/můžu použít Roslyn.
Už zítra vypukne konference WUG Days 2023.2 a následovat bude SQL Server Bootcamp 2023. Protože čtete tento text, asi vás zajímá, jaké přednášky jsem připravil.
I was today’s years old when I realized I can create class named end
in C#.
I’ll be at this year’s WeAreDevelopers World Congress. I’m running a workshop Writing and measuring high performance code with latest .NET and C# features.
.NET fwdays’23 is happening 17 June and I’ll have one session there Making boring old WinForms game fun and cool with latest .NET features and cloud.
Příští týden se bude konat Gopas TechEd. Letos jsem připravil 3 přednášky.
For my day to day calls I’m using Logitech Brio webcam. It provides very decent picture quality and I like using Windows Hello for unlocking my PC. But I was experiencing major issues. Here’s a (weird) solution that worked for me.
I’ll be speaking at Techorama 2023 happening May 15-17. This year I’ll have one session and one workshop. The session is What’s new in Entity Framework Core 7. The workshop is Mastering Entity Framework Core.
This Saturday I’ll be speaking at Warsaw IT Days 2023. One sessions What’s new in C# 11 will be in-person in Warsaw, while other C# Source Generators – let the machine do the programming is VoD.
I recently put Tigo optimizers under remaining solar panels on my roof and also equiped my system with CCA (and TAP). During the whole process I contacted support few times and I was blown away by the quality of it. I don’t think I’ve ever had such an overwhelmingly good experience dealing with support.
Včera se konala konference WUG Days 2023.1. Měl jsem jednu přednášku se jménem What is QUIC protocol and how we can use it from .NET. Níže je ke stažení prezentace a demo.
As promised in previous blog post. Let’s implement that sum function using generic math from C# 11.
Some time ago I wrote blog posts playing with head- and tail-like functions and implementing sum function in C# using these. With the recent addition of list patterns into C# 11, I revisited that topic.
This combination of Task
and IDisposable
surprised me quite well. And yes, it’s my fault. As usual.
I was having one of those ideas that is useless at that given moment in time but might become the secret weapon in the future. This time it’s about application, Firebird Embedded and FbNetExternalEngine.
The feature I’m most excited from freshly released C# 11 is raw string literals. You can read about the feature more here. In this blog post I’m going to try some limits. For fun. And learning.
I’ll be speaking on MS Tech Summit 2022 (online) this Friday. I’ll present two sessions: What’s new in C# 11 and Azure Spot instances as your secret weapon.
Tak .NET 7 a C# 11 máme finálně venku. Příští čtvrtek na WUGu se tomu podíváme na zoubek.
This took me quite a while to debug, because I was constantly wrongly assuming my threading and synchronization context handling was wrong. At the end of the day it was very simple, I just couldn’t see the forest for the trees.
I usually create arrays like this. Nothing fancy. And most people around me use the same. I would even say it’s kind of a standard way in C#.
var data = new[] { 1, 2, 3 };
But today I realized, you can also use this (target-typed new expressions) when using arrays.
New version 9.1.0.0 of ADO.NET provider for Firebird is ready for download. This release adds new features here and there and also some bug fixes. Notable features are support for parallel workers (planned for Firebird 5) and support for “at number” for snapshot transactions.
Recently I spent surprising amount of time chasing behavior that didn’t match my expectations. As you can guess the problem was between keyboard and chair. Hopefully my mistake can help you save minutes (or hours) of debugging.
Tento týden se konají dvě akce, kde budete mít možnost poslechnout si několik mých přednášek.
První v pořadí je SQL Server Bootcamp 2022, kde si budete moci poslechnout Autoincrement (identity) není jediná možnost jak generovat PK. Následovat bude WUG Days 2022, kde mám Entity Framework Core 7 – Co nás čeká, Co čekat od .NET 7 a C# 11 – Co nás čeká.
After the Belgium version Techorama is going to Netherlands, in October 10-12. I was lucky one of my session was selected – C# Source Generators – let the machine do the programming.
Oh yeah. .NET Developer Days 2022 is coming. Can’t wait to be there. This year, I’ll be doing workshop as well as sessions. Lucky me.
Three years ago (yes, I looked it up), I wrote a blog post about switching from warnings in NRT to errors. But it required manually adding codes for all the warnings (luckily thanks to Roslyn being open source, it’s not that difficult) and keeping that list up to date. But recently I found much simpler way.
Můj výběr malých, ale přesto zajímavých, novinek v .NETu 6. Dnes 21.6.2022 od 17:00.
This Saturday (June 4th) at 19:00 (CEST) you can join the Rockin’ The Code World with dotNetDave live stream and listen to me and David McCarter talking about stuff like evolution of C#, databases, .NET performance, Entity Framework, open-source and probably more.
Příští týden se bude konat Gopas TechEd. Po několika letech online verzí, tentokrát v hybridním provedení. Letos si z mé strany můžete poslechnout jednu in-person i online přednášku a dvě čistě online.
Sometimes people ask me a question where the answer requires some kind of dialogue or follow-up questions and/or is too long to type. Thus, I’m trying new way of recording the conversation and then posting it for anybody to watch.
Sometimes it is in Czech (like this one), sometimes in English. Sometimes one person (and me), sometimes multiple.
Do you have an interesting question? Send me an email and let’s chat about it.
Now, here’s the recording:
New major version 9.0.0.0 of ADO.NET provider for Firebird is ready for download. Major version number change, big changes. Buckle up.

I’ll be speaking at Techorama 2022 happening May 23-25. And I’m very excited about it. Over the last decade or so I was working with/for Belgium based company on and off, so Belgium has somewhat special place in my heart.
Two of my sessions were selected. First is C# Source Generators – let the machine do the programming and other is Performance with Span<T> for dummies (should I care?).
20.4.2022 od 8:30 budu mluvit v rámci akce IT Ráno, kterou pořádá Gopas, o možná trochu méně známých novinkách v .NET 6, o kterých ale přesto stojí za to vědět. Registrovat se můžete zde.
Silly question, right? Whatever the limit is, it is surely beyond what one should practically ever write. Right? But as with mine other explorations of limits, I’ll try it anyway.
With the 20 years of .NET that’s happening now and also the Celebrating 20 Years of .NET: Entity Framework I realized, I have a piece of history that would be too bad to lose.
I’ll be speaking on MS Stage (online) February 25th April 1st. I’ll show you what Source Generators are and how to create one yourself.
Today I learned that you could use attribute, in C#, on itself. 🤯 Not sure why would I do that, but it’s cool.
As I was (at that moment) running out of ideas about optimizations in hot paths in FbNetExternalEngine, I turned my attention into other parts of code. And one piece that was doing casting on every call caught my attention. Could I make the casting faster? What is actually the cost of casting? Does it matter? I had to dive into it.
As I was writing bunch of if
s today, I was thinking whether it would be possible to use pattern matching from recent versions of C#. To make things more interesting, I was comparing multiple values and it was not a simple equality. Blindly typing the code, I was very surprised Roslyn didn’t complain.
When I read World’s Smallest C# Program (featuring `N`) I was so intrigued. I had to give it a shot myself.
Moje další přednáška ze série .NET 6 extravaganza, tentokrát o Entity Framework Core 6. 27.1.2022 od 17:00.
