I usually pass configuration to my web API via JSON files, but recently I needed to pass them also via command-line arguments. As the solution for ASP.NET Core 2.x is quite different than for ASP.NET Core 1.x I decided to describe both methods in here.

If you were looking for information about API versioning support for ASP.NET Core you’ve probably come across Microsoft.AspNetCore.Mvc.Versioning library. The library itself allows you to set up versioning in a couple of different ways, for instance, via attributes or via manual convention setup. All of this options are really nice but unfortunately, they have one significant drawback, namely, you have to set them up manually. As I tend to forget about th...

Working with Tasks is a modern way of writing asynchronous code in an easy and flexible manner. It is quite straightforward to start using them, so usually developers do not investigate thoroughly the topic. Unfortunately this often leads to unpleasant surprises - especially when it comes to exception handling. Having this in mind let's take a look how to handle exceptions in Task and what can happen if we do it wrong.

Although ECMAScript6 has not been officially released yet, we can play around with new language features today. There are tools such as Traceur or Babel which are able to convert ECMAScript6 into ECMASciprt5, thus we are able to run the code in every browser. So let's try to run the snippet below, which leverages destructuring assignment using those tools ...

There are couple of ways of injecting dependencies into AngularJS components. The most common one is just to specify the dependency name in the function's argument list (function() { angular .module('app') .controller('shellCtrl', function ($scope, $http) { $scope.title = "Title"; }); })(); However this technique fails in real life scenarios, because for production we usually (or rather always) minify and uglify javascript files. Uglify proces renames our varia...

Let's assume that we have a simple table GL_Task which looks like this I was asked to rewrite simple SQL query SELECT Id,Name,IdProject FROM GL_Task WHERE Name = 'First task' OR Id IN (3,4 /more id's to come/) using NHibernate's QueryOver API. As simple as it may seem, solution for this particular problem is not straightforward. My first (not so clever) attempt was simply combining WhereRestrictionOn and Where clause var result = session.QueryOver

Everyone who has ever tried to create multilingual application knows, that this is very tedious task. The most repetitive work is usually moving hard-coded strings to resource files. Fortunately with Resharper this is definitelly less painfull than usuall. In order to point out localizable parts of application , it is necessary to decorate classes with System.ComponentModel.LocalizableAttribute. However, usually we want to localize an entire program, so more universal solution is to set appropria...

Introduction I think one of the most important features of Resharper is on-the-fly code quality analysis. Basically, every time Resharper finds possible pitfall in code, it indicates this with appropriate warning. The most common warning is "Possible System.NullReferenceException". You can easily reproduce it by writing this code List

I think almost every .NET developer is familiar with INotifyPropertyChanged interface. Typical implementation of this interface looks more or less like that: public class NotifyPropertyBase : INotifyPropertyChanged { public event PropertyChangedEventHandler PropertyChanged; protected virtual void OnPropertyChanged( Expression

Introduction In the company I'm currently working for, it is a common practice to use Devexpress XtraReports to create all kind of reports. Usually these reports are embedded into html page and used along with DevexpressReportViewer. However, lately I have been asked to open a report as a PDF file, without putting a viewer into a html page. 1. First approach After some digging, I created an action in controller which looks like this public void ExportToPdf() { using (MemorySt...
