Steve Sanderson, the original creator of Blazor, recently posted a quick peek at some of the new Blazor prototypes they are experimenting with for .NET 8. I think this looks great. Mixing client and server is a brilliant concept. Essentially one would be served with server-side Blazor on the first landing. While using the app, a background task would download the client-side stuff, ready to be consumed at any subsequent access....
Today, my last self-assigned duty before the Christmas break was to migrate our in-house rate-limiting implementation (based on the AspNetCoreRateLimiting third-party package) to the new, shiny rate-limiting middleware introduced by ASP.NET Core 7. While the process was relatively straightforward, I stumbled upon a few quirks I want to annotate here. Our use case is simple. We use what the ASP.NET Core 7 documentation defines as a “fixed window limiter.” It uses a specified time window to limit requests....
Today I upgraded to JetBrains’ Rider 2022.3. Startup speed has been enhanced, and full .NET 7 and C# 11 support is included. So far, my favorite feature is the conversion of regular and verbatim strings into their raw counterparts (it’s often the small, simple things.) My second best is the fulls upport for WSL2 remote development. This one took a good while to come out of the trenches, but better late than never, I’d say....
The other day we did a .NET 7 Spotlight event at this month’s DevRomagna meetup. The speakers were Ugo Lattanzi and me. In my session, I chose to talk about my top 7 new features in .NET 7 (pun intended.) What follows is a mix of my preparation notes and what I ended up really saying1. 1. Performance Since the initial release of “new dotnet” (.NET Core), performance has always been a critical goal for the ....
Today I released v3.4 of FatturaElettronica, a .NET open source project that allows validation and de/serialization of electronic invoices adhering to the standard defined by the Italian “Agenzia delle Entrate”. It’s doing very well for such a niche project, with downloads now well beyond the one hundred thousand mark. Be aware that this release anticipates support for v1.7.1 of the specification going into effect on October 1, 2022. For more information, see the appropriate ticket and the changelog....
I am happy and humbled to have been awarded the Microsoft MVP Award for the seventh consecutive year. July 1, the award assignation day, always comes with curiosity and a bit of trepidation. Being a member of the MVP community has been a very positive experience for me, especially in the years before COVID, when the MVP Summit, the main MVP event, was held in person in Seattle at the Microsoft HQ....
If you understand Italian, the recording of my Playwright session at UGIdotNET’s WebDay 2022 is now available on YouTube1. Playwright is a phenomenal cross-browser, cross-platform, cross-language, single-API, mobile-friendly front-end testing tool. I’m looking forward to giving the same session in English sooner or later, but I should first win my laziness and start looking for exciting events with open CFPs. If you happen to know one, please let me know....
The first preview of C# 11 is out, and well, I think I like what I see. I dig the new List patterns and am a fan of allowing newlines in the “holes” of interpolated strings. Parameter null-checking is a bit contentious, and it’s good that they are releasing it in preview one and asking for feedback. In a nutshell, they want to spare us a lot of boilerplate. Code like this:...
I spent the last few days migrating our ASP.NET REST services, MVC web applications and Blazor server apps to .NET 6. Overall the process was pretty straightforward. The few issues I went through were easy to solve and well documented. Things got more involved with the EF Core 6 transition, especially with the Npgsql Entity Framework Core Provider. The official ASP.NET Core 5.0 to 6.0 migration guide was my first stop....
A few months after I released my first .NET open source project (a niche one targeting the Italian fintech world), I was contacted by a representative of Team Digitale, the digital innovation branch of the Italian Public Administration. He suggested joining the Developers Italia initiative and moving my project to the their organization on GitHub “to enjoy enhanced visibility and broaden the audience”. I politely refused. I did not doubt my counterpart’s good faith....
