There is a big buzz about AI these days and major Cloud vendors like Amazon Web Services, Azure, Google Cloud are competing to bring better products to their platforms for variety of AI tasks. One of these services is speech recognition and generating transcription text from the audio. I recently worked on a project which involved transcribing large amount of daily generated audio recordings...read more

Over the time various techniques to manipulate database data have evolved in .NET. Entity Framework is certainly the most advanced one, but for small ad hock applications where you have few inserts to deal with, ADO is still the fastest way to write data to the database...read more

Paging a REST API response is equally important as filtering the data returned through REST API endpoints and they quite often come together. Just like filtering, paging limits the amount of data returned from the endpoint, saving both client and server side resources...read more

Apart from running on Windows and Linux both x86 and x64 architecture, .NET Core is an ideal platform for IOT (Internet of things) projects because it can also run on ARM32 and ARM64. This means you can run it pretty much any device with both RISC or CISC processor architecture. If you are .NET developer or you are familiar with .NET platform and C# language, this means you can now write applications that run on Raspberry Pi which is based on RISC architecture by writing them in Visual Studio...read more

Starting from .NET Core version 2.1, there are so far three types of WebApi responses that controller actions can return. All three types had it's own pros and cons but all are lacking in options to satisfy both REST and the high level of testability. The available response types in ASP.NET Core including recently released 2.2 version are ...read more

Now here is a trouble that was bugging me for some time and I guess who ever is using IConfigration injected in the constructor and using extension methods to access configuration values reached whan trying to write Unit Tests. IConfiguration interface is a great way to easily replace your configuration layer in application, but it has it's drawbacks. The way interface envorces configuration reading is by exposing GetSection method which return IConfigurationSection...read more

Tracing data changes can be beneficial in narrowing down the issue that may occur in production. If you are using Entity Framework Core you have several ways to store actions performed against your data...read more

Entity Framework Core implements optimistic concurrency strategy which is opposite to pessimistic concurrency strategy. Lets's first clear out what are main differences between these two approaches in concurrency control. Optimistic concurrency control allows multiple processes to access and modify data without any explicit lock on the data...read more

Versioning of your endpoints is important especially if you have 3rd party dependent clients of your REST API service. Any change in your endpoint, for example in data structure may impact clients even if it is backward compatible, clients may process your endpoint data in different ways, so even adding one additional property to your model may also impact functionality of the client which is consuming your endpoint. Prerequisites ...read more

If you are building .NET Core application your choice for logger library is most likely Serilog. It is really powerful and easy to use library which allows you easy logging in all levels in your application. One of the best features it has is easy extending of the data you want to have in your logs...read more

Logging is an essential part of the application. It gives you insights which allows you to see your application behavior or even user behaviour and actions taken by them in the application.Serilog is most probably the most popular library for logging in .NET Core applications...read more

Tagging Docker images is important to keep track of versions of the service running and to easily roll back in case of faulty behavior of the application. The version strategy which is the most clear and understandable is tagging image with version of the application for example ...read more

Recently I wanted to try to spin up a simple .NET Core application on my local cluster which I built in my previous article Manual setup of Kubernetes cluster on a Virtual Machine with kubeadm. The problem I had is that I needed to test applications in this cluster and deploy them as service in order to monitor potential issues behavior. As deployment of Kubernetes service needs an image to pull from, I decided to use dockerhub to push my test images, but they first needed to be created. ...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

For my website, since it runs on Umbraco 6 and it is basically ASP.NET MVC application. To reduce load time and increase website performances I decided to alternate the response of the application and minify it using simple regular expression. Initially I was trying to do this with YUI Compressor library which has .NET port as NuGet YUICompressor.NET which works fine in most of the cases, but in my case does not skip PRE tags which I use for code snippets on the website...read more
