When you open your IDE you can only stare on that blinking cursor, your mind is blank and you don’t know what to do. I’ll tell you why this happens and what to do about it. ...
Why do I think you only need 3 or 4 programming languages? Because I think that with 4 different languages represents big enough array of programming techniques to complete (almost) any project. It’s not about the languages itself, but rather the way of thinking and working which helps us become better as software developers and cover large area of projects which you may encounter. But the main point of it is that it gives you wide array of skills, presumably enough to learn any other language and easily get you a job. ...
It’s an interesting feature. In some cases it’s better when users can preview image before uploading it, e.g. when you want to let users trim the image or process it in any way.

Reflection code snippets tested under .NET Core 2. What is reflection and how can you benefit from it Reflection allows a program to inspect or modify itself during runtime. In practice it means that you can do all sorts of stuff on objects/properties including checking type of an object at runtime (typeof), listing all fields of an object without knowing variable names (including private members), modifying properties of an object (also including private members), instantiating object by class name and ivoking its methods dynamically, inspecting attributes attached to objects/properties, finding all classes implementing given interface in an assembly and so on. ...
One of the many security risks which you should consider is a mass assignment vulnerability (cheatsheet) also know as overposting. While it’s not in OWASP Top 10 it’s still considered important. Read on to understand the issue and find out possible ways of fixing it. Mass assignment explained ASP.NET Core allows automatic model binding of request parameters into variables or objects to make developers life easier. It can be as simple as binding id parameter via route: ...
