Entra External Identities over B2C — lessons from a greenfield product

Sat, 04 Apr 2026 10:00:00 +0200

In early April I recorded a VoD for Warsaw IT Days 2026 about Microsoft Entra External Identities — the Polish title was something like “scalable cloud auth without rolling your own AuthN/AuthZ stack.” English write-up here. YouTube recording · demo repo.

I picked the topic partly because of the calendar. Azure AD B2C is not vanishing overnight — Microsoft still supports existing tenants until at least May 2030 — but the product line has been in wind-down for a while. New customers could not buy B2C after May 2025. B2C Premium P2 went away on 15 March 2026, a few weeks before I sat down to record. No new features land on B2C anymore; External ID gets those instead. If you are starting a B2B portal in 2026, that is worth knowing before you copy an old B2C sample repo.

AzureDay Poland 2026 — security hits, skipped AI tracks, and a hotel I had seen before

Sun, 22 Mar 2026 18:00:00 +0100

Thursday, 12 March — AzureDay Poland 2026 at Airport Hotel Okęcie in Warsaw. My second time at the event, same venue as last year. Small coincidence: I had already slept in that hotel as a regular guest on the way back from Ignite in San Francisco a few months earlier. Conference day turns the lobby into badges, queues, and sponsor stands; a Tuesday night layover is just a quiet corridor and room service. Same building, completely different atmosphere.

OpenSSH Beta on Windows

Fri, 23 Feb 2018 19:16:38 +0200

As mentioned in previous post, the time has come to install proper development tools on every environment that I used. And so I had my first chance to use OpenSSH Beta on Windows.

While installation is rather simple (and does not require to reboot computer — looks like Microsoft is finally learning something from *nix Systems), for configuration there were some surprises for me. See the post details to read more about it!

Google Authorization in ASP.Net MVC 6

Sun, 03 Jan 2016 19:15:54 +0200

So, as the new year break is coming to an end, I finally found some time to look into new ASP.Net 5 MVC version (currently marked as a Release Candidate) and started working on some simple project that I currently call FoodyRater on Visual Studio 2015 Community version. First things that I decided to set up was website layout and authorization by Google account.

As for layout, it went surprisingly smooth — I just right-clicked project name, selected “Managed Bower Packages” and replaced Bootstrap/jQuery with ‘Admin-lte’ package. Then all I had to do was change the shared _Layout.cshtml file and everything started working.
