By Joydip Kanjilal When developing database-driven .NET and .NET Core, regardless of the database we intend to deploy in the end, we will often want to work with a database engine that is lightweight and fast, in order to execute tests quickly and speed up development. Here SQLite is an ideal choice. You can use SQLite to gain both faster data access and a smaller footprint. The SQLite database is usually stored as a single disk file, although it can also work as an in-memory database. However, unlike an in-memory database, SQLite allows you to query data without having to load the entire data...

By Joydip Kanjilal ASP.NET Core offers a simplified hosting model, called minimal APIs, that allows us to build lightweight APIs with minimal dependencies. However, “minimal” doesn’t mean minimal security. Minimal APIs need authentication too. We’ve explored JWT authentication in an earlier post here. In this article we’ll examine how we can build a basic authentication handler for minimal APIs in ASP.NET Core. Below we’ll implement a basic authentication handler that will identify and authenticate the user. Because we will validate the user’s identity using credentials stored in a database, w...

By Joydip Kanjilal ASP.NET Core offers a simplified hosting model, called minimal APIs, that allows us to build lightweight APIs with minimal dependencies. Ideal for building fast and simple services, minimal APIs were initially introduced in ASP.NET Core 6 to strip away the complexity of traditional APIs and make it easier to build microservices. The goal of this post is to explore the new features for building minimal APIs introduced in ASP.NET Core 8. To use the code examples provided in this article, you should have Visual Studio 2022 installed in your system. If you don’t already have a c...

By Joydip Kanjilal A high-quality application must be stable, performant, scalable, and reliable. The reliability of an application depends on many factors, but one of the most important is resiliency, or the ability to withstand failures or faults during run time. In this article, we’ll see how we can bring resiliency to database connections in ASP.NET Core using Entity Framework Core. EF Core has a feature called connection resiliency that automatically retries failed database commands to maintain connectivity during transient errors or network instability. By encapsulating the logic for ide...

By Paul Krill Parasoft has launched a tool to enhance safety testing for C and C++ applications. The tool comes at a time when the two venerable programming languages have come under fire over safety concerns. Announced April 8, the C/C++test CT (Continous Testing) tool is intended to empower large developer teams to build reliable and dependable embedded systems. It provides a comprehensive solution for large teams engaged in the development of safety-critical and security-critical C and C++ products, Parasoft said. C/C++test CT integrates with developers’ desktop environments such as Visual ...

By Joydip Kanjilal With the release of .NET 8, Microsoft introduced a plethora of new features and enhancements in the .NET Core and ASP.NET Core frameworks. One such feature is the SearchValues class, which marks a significant step forward in efficiently fetching data from data sets. SearchValues is a new type introduced in .NET 8 designed to improve application performance. By using optimization techniques like vectorization and hardware acceleration, SearchValues delivers speed enhancements while seamlessly blending with .NET Core and ASP.NET Core. In this article, we’ll explain how you can...

By Serdar Yegulalp Over the past decade, Rust has emerged as a language of choice for people who want to write fast, machine-native software that also has strong guarantees for memory safety. Other languages, like C, may run fast and close to the metal, but they lack the language features to ensure program memory is allocated and disposed of properly. As noted recently by the White House Office of the National Cyber Director, these shortcomings enable software insecurities and exploits with costly real-world consequences. Languages like Rust, which put memory safety first, are getting more att...

By Joydip Kanjilal When working on applications, you will often need to represent a group of constants in the business logic and even in the domain layers. However, you should avoid using enumeration types, or enums, in the domain layer and instead use alternatives such as record types. Why? In this article, we’ll explain the downsides of using enumerations in the domain layer.

By Paul Krill C++ creator Bjarne Stroustrup has defended the widely used programming language in response to a Biden administration report that calls on developers to use memory-safe languages and avoid using vulnerable ones such as C++ and C. In a March 15 response to an inquiry from InfoWorld, Stroustrup pointed out strengths of C++, which was designed in 1979. “I find it surprising that the writers of those government documents seem oblivious of the strengths of contemporary C++ and the efforts to provide strong safety guarantees,” Stroustrup said. “On the other hand, they seem to have real...
