I assume since you are reading this article you are involved in development of applications using C# and .NET platform. Microsoft .NET and C# have been around for quite a while but there is not much talk on haw you can use C# for writing code apart from creating your projects in your IDE of choice and compiling them to executables. This is typical approach for writing robust applications and that is fine, but from time to time, this whole ceremony of creating a project, adding packages and libraries just to run for example a simple scheduled task that cleans up old logs from IIS seems like and overkill...read more

Object relational mappers or ORMs are a great tool which can significantly reduce application development time, but if they are not use wisely they can cause bottlenecks and performance issues. Same goes for dependency injection containers. The lifetime of the components, especially the ones that can cause recurse locks like SQL Server connections must be as short as possible and they should be released as soon as work is done. ...read more

.NET Core has done a great job by introducing interface for most of classes which makes them easy to write unit tests around them. However, there are a lot of classes that re commonly used which are not refactored in .NET Core...read more

This is not a new subject and the support for handling WebApi input and output was introduced in .NET Core 2.0 and it's been there since then. There are couple of useful pages out there and it is even well documented on Microsoft official page Custom formatters in ASP.NET Core Web API...read more

With growing popularity of dotnet Core, Git and Docker, developers who used to work mainly on Windows are now getting used to CLI environment and obviously Linux. Windows is still a development environment platform of choice, bit since Microsoft already developed and published Visual Studio Code as a cross platform IDE for Windows, Linux and Mac. Although it is still not mature as Visual Studio 2017, it is a decent tool for .NET Core applications development...read more

In memory caching is not a bullet proof way of caching data in an application, especially if this application is distributed. The lack of synchronization between nodes can cause you application to misbehave showing wrong data or even throwing exceptions and crashing. This is one of the main reasons why distributed caching is the best way of doing the caching in your web application. But not all applications you might be developing need to run as distributed on multiple machines...read more

One of them is definitely a custom solution that can track and store count of every visit per page you have, or without any re-inventing of wheel you can just hook to Google Analytics API to pull the data...read more

Few months back I wrote an article on how to create Linux daemon in .NET Core using generic host class introduced in 2.1 version of .NET Core. This code works just great on Linux OS when configured as a daemon in systemd and provides more less same concept you would have with Windows Service written in .NET Framework 4.x. The code works just fine on both Windows and Linux hosts, but because it is compiled as a Console Application, you do not really get to run it on your Windows machine as a Service...read more

Limiting the number concurrently running Tasks is not that often requirement in a code, but eventually you'll find yourself in the situation that for the most likely performance issues you'll have to limit number of concurrently running Tasks. One of these situations is when you have long running operations in the Task. If you spin up to many Tasks you will seriously degrade your application performance...read more
