Azure DevOps Pipeline vs. .NET Core 3.1

Yesterday I have updated the target of my personal projects to .NET Core 3.1 and immediately I had a problem with the continuous integration in DevOps: all my build failed with this error:

“error NETSDK1045: The current .NET SDK does not support targeting .NET Core 3.1.”

Well, the problem seems to be that .NET Core 3.1 is not directly supported in the “native” DevOps Pipeline and to make it work, you need to add an “UseDotNet” Task, to download the framework you need.

This is the fragment of my YML configuration file:

# ASP.NET Core (.NET Framework)
– task: UseDotNet@2
    packageType: ‘sdk’
    version: ‘3.x’
    includePreviewVersions: true

Mac apps will be retired in 2020

My dear MyUptime/GTUptime and GTFractals users, with the beginning of the new year 2020 I decided not to renew my commitment for the development and publishing of Mac/iOS Apps. Unfortunately I miss time and I moved my interest somewhere else.

I want to take the time to thank you once again for having had fun with my software and I hope you enjoyed a bit the result of my work 🙂


Say hello to GT Uptime!

During the last night, Apple has approved and published into the Mac App Store the new GT Uptime.


GT Uptime is the new version of My Uptime: it brings all what has been appreciated in the old app (including the In-App Purchase of course!) plus, as a new features, the possibility to see directly in the app’s Menu the charge of the battery into a progress bar.

This is the link from which to download GT Uptime.

Say hello to GT Fractals!

This night Apple has approved my second app on the Mac App Store: GT Fractals.

The purpose of this App is really simple: to allow the user to explore and display the Mandelbrot Set, one of the most famous Fractal.

Despite this is a brand new app (I’m incrementing the time spend on my App because of my goal to achieve a good experience with Swift & Cocoa/CocoaTouch) it has a long history. It’s since at least 1992 that I’m interested into the Mandelbrot Set and writing software to explore it.

I hope you’ll like this new App: keep in mind that it’s just a starting point, new Fractals are yet to come! Of course in case of suggestions and/or problems, just use the contact form of this website.
