Pourquoi C# reste aussi décrié par les libristes, et pourquoi ils ont raison ?

– Le langage C# est normalisé ECMA, mais n’est que open-source
– .NET Core est libre (licence MIT), mais reste sous l’EULA Microsoft... je ne sais pas comment ca se résoudrait devant un juge.
– Le compilateur est libre (Roslyn, licence MIT).
– Xamarin, le cross platform implementation, est privateur
– je ne parle pas du compilateur indépendant MONO

Donc on peut vite penser que C# et .NET sont libres, mais en vrai, ils s’adossent à des outils qui ne le sont pas. On peut tomber dans des superpositions de licences qui ne sont pas libres, juste open-sources.

Et n’oublions pas : L’open-source, c’est la laisse que le maitre a faite tomber au sol, mais qu’il peut reprendre à tout moment.

Why you should check values of public methods’ parameters
▻https://hownot2code.com/2021/10/22/why-you-should-check-values-of-public-methods-parameters

This note will answer the question – why PVS-Studio considers parameters of public methods potential sources of tainted data. The analyzer can issue warnings if such parameters haven’t been checked before use. The point is that undue confidence in external data may lead to various vulnerabilities – SQLI, XSS, path traversal and others. Most obvious … Continue reading Why you should check values of public methods’ parameters

How to Unwrap an AggregateException Thrown by #aws #lambda

https://cdn-images-1.medium.com/max/1024/1*zEBtn3FyT0jD78047BvStQ.png

If you’ve written a .NET Lambda function which calls async code and returns either Task or Task<T>, you’ve probably seen an AggregateException which wraps the real exception.This example comes from the handler below which calls an asnyc method that always throws a FormatException.The AggregateException can be unwrapped, though. When AWS added .NET Core 2.1 support to Lambda, they also added an undocumented feature toggle. The only real mention of it is by the AWS .NET team on Reddit.When the UNWRAP_AGGREGATE_EXCEPTIONS environment variable is set to 1 or true, Lambda will call GetAwaiter().GetResult() instead of using theResult property.Note that this only works if your method returns Task or Task<T>.This causes the first exception thrown to be returned instead of an (...)

SourceWhen I started my very first career in software development many years ago, I remembered that I really like to learn and achieve a lot of skills in software development via read notably books by gurus in this fields as well as read blogs of them. Some of the very famous books that I have read are Code Complete: A Practical Handbook of Software Construction, The Clean Coder: A Code of Conduct for Professional Programmers, Design Patterns: Elements of Reusable Object-Oriented Software, Refactoring: Improving the Design of Existing Code, and so on. And I strongly believed that all developers just like me also stepped into the software development industry in this way.By the time, I wondered how to share what I have learned to the software development communities out there so that it (...)

A Token Smart Contract Executing in Native C# / .NET on #stratis

The First Token Smart Contract Executing in Native C# / .NET on StratisNote: Hundreds of you have been messaging me that X other platform has smart contracts in C#. I can say with certainty that Stratis is the first to be executing C# natively. Other platforms (e.g. NEO) may be compiling C# syntax to custom machine code but we’re definitely the first to be executing actual .NET code on the Common Language Runtime, .NET’s virtual machine. (I should know, I previously built EthSharp which compiled C# for the EVM!)Over 12 months ago, slightly frustrated with the “young” state of solidity and #ethereum smart contract development environments, I started craving bringing my favourite development environment (C# / .NET / Visual Studio) to #blockchain development. Over the course of a couple of months I (...)

Exploring what could be the Universal Windows Platform at its finest.All code for this article can be found here.Whilst Microsoft’s mobile offering is well and truly dead, their push to provide platform agnostic solutions for developers is alive and well. #xamarin.Forms’ growth has accelerated since Microsoft purchased Xamarin back in 2016 and with .NET Core & .NET Standard providing a simple way to create libraries for all targets easily, C# is becoming a go-to language for creating quality software that scales.That being said, the ecosystem for mobile app development is also evolving and it’s not hard to get the idea that Xamarin.Forms may not be the go-to solution for mobile app development. Both iOS & Android have beloved languages for native applications in Swift and Kotlin (...)
