Application Pools in IIS can be somewhat of a mystery. Since they’re created for you automatically many times Administrators don’t give them a second thought. But understanding application pools is crucial to having a good running IIS server. 

Since October 2015, the WPF designer from SharpDevelop has been a standalone component that can be re-used in any application that needs to integrate a XAML designer. That component is now free of dependencies.

Typescript full course | Zero to Mastery

In this course, we are going to start at the basics of TypeScript and how primitive JavaScript data types integrate into the work of TypeScript. There is going to be challenges along the way to strengthen basic concepts.

Dropzone.js is a light weight JavaScript library that turns an HTML element into a dropzone. This means that a user can drag and drop a file onto it, and the file gets uploaded to the server via AJAX.  Demo

ExtCore allows you to decouple your application into the modules (or extensions) and reuse that modules in other applications in various combinations. Each ExtCore extension may consist of one or more projects and each project may include everything you want (as any other ASP.NET Core project). Controllers, view components, views (added as resources and/or precompiled), static content (added as resources) will be resolved automatically. These projects (extension pieces) may be added to the application directly as dependencies in project.json of your main application project (as source code or NuGet packages), or by copying compiled DLL-files to the Extensions folder. ExtCore supports both of these approaches out of the box and at the same time. 

There are two MySQL providers for Entity Framework Core:
- The official one from MySQL: MySql.Data.EntityFrameworkCore. As of now, the latest version is 8.0.19, and works with Entity Framework Core 2.1 (and probably also 2.2). Since EF Core 3.0 is a major version with breaking changes, you cannot use it with this provider.
- The Pomelo provider: Pomelo.EntityFrameworkCore.MySql. There is a 3.1 version of this provider.
In other words, if you want to use EF Core 3.0/3.1 with MySQL, at this point you need to use the Pomelo provider (or wait for the official MySQL one to get released).

In order to cleanse the data as we parse it, we thought using a try/catch would be ok. If we don’t catch the exceptions, we’re good, right?
Turns out it kills our performance when we throw a lot of exceptions, even if we don’t catch them. Each exception has some costs . We needed to find a way to handle this data without involving exceptions.
TryParse turns out to be a method designed to solve our problem. We ran some benchmarks to prove it. 

Singleton design pattern is one of the simplest design patterns: it involves only one class throughout the application which is responsible to instantiate itself, to make sure it creates not more than one instance; in the same time it provides a global point of access to that instance. In this case the same instance can be used from everywhere, being impossible to invoke directly the constructor each time.
