NET CORE business layer service automatic registration – DI
<strong>App background In the development of the three-layer structure of net Core, many people still use the manual registration method, which is to write code to register. Generally, there is a class in which all the implementation classes corresponding to the XX interface are manually registered, such as code. I’m lazy and don’t like to […]
ASP.NET Core Globalization and Localization Series 2
In actual work, we often use ASP.NET Core’s Globalization & Localization features and resource files. Resource files (.resx) are used to separate language strings from code. These files contain key/values items. , you can use vs to create this file, for example: Your website supports 3 cultures – French, Spanish, English, so you have to […]
BindingFlags in C#: Core enumeration types for reflection
The C# programming language provides a very powerful feature: reflection, which allows us to dynamically obtain and operate type information at runtime. Reflection can be used to implement many advanced functions, such as dynamically loading assemblies, creating object instances, calling methods, accessing fields and properties, etc. To use reflection, we need to use some classes […]
.net core webapi implements localization
Nowadays, projects often require support for localized configuration. There are many ways to achieve localized configuration. For example, Microsoft’s official website provides localized configuration through resx resource files and PO files. However, the scalability of resx resource files is not good, and PO files need to introduce dependency packages. This article mainly introduces another scalable […]
Locust single-machine multi-core stress test, and data communication processing of master-slave nodes
Let me briefly explain the background first. Before the APP is launched, the login interface needs to be performance tested. After evaluation, I gave priority to locust for script development. This time I used locust’s single-machine multi-core running capability, but it also involves data communication between master and slave nodes. There are very few effective […]

Linux implementation principle – multi-thread scheduling overhead and performance optimization in NUMA multi-core architecture
Foreword NOTE: The “thread” referred to in this article refers to the executable scheduling unit Kernel Thread. NUMA Architecture The design concept of NUMA (Non-Uniform Memory Access, non-uniform memory access) is to partition the CPU and Main Memory autonomously (Local NUMA node), and to cooperate across regions (Remote NUMA node), in this way to alleviate […]
ASP.NET Core Web API development practice using Dapper
