.NET CultureInfo in Windows 10

Did you know that the CultureInfo behavior with “unkown” cultures has changed with Windows 10? I stumbled two times about this “problem” - so this is enough to write a short blogpost about it. Demo Code Lets use this democode: try { // ok on Win10, but not on pre Win10 if culture is not registred CultureInfo culture1 new CultureInfo("foo"); CultureInfo culture2 new ...

A first glimpse into CAKE

Since a couple of years I use FAKE (C# Make) to configure my builds. Also at the YooApps we use FAKE in some projects. One of the projects uses it since more than two years. FAKE is really great and I love to use it, but there is one problem with it: The most C# developers don't really like to use new things. The worst case for the most C# developers - it seems - is a new tool, that uses an exotic ...

Neuerungen für Visual Studio für Mac

Visual Studio für Mac wurde im November 2016 veröffentlicht – eine voll ausgestattete IDE, die Mac-Entwicklern dabei helfen soll, mobile und Cloud-Anwendungen zu erstellen. Für den Anfang wurden Xamarin für die mobile Entwicklung und .NET Core für die Cloud-Entwicklung eingesetzt. Seitdem wurde einiges an Entwicklerarbeit in das Projekt gesteckt. So wurde C# Code, der ...

Please use a password manager

Since years, I'm using a password manager to store and manage all my credentials for all the accounts I use. The usage of such a tool is pretty common for me and it is a normal flow for me to create a new entry in the password manager first before I create the actual account. I'm always amazed, if I meet people, who don't use any tool to store and manage their credentials. They use the same ...

Blogging with Git Flow

Since a while we use Git Flow in our projects at the YooApps. Git Flow is a add-in for Git, that helps us to follow the feature branch process in a standard way. We usually use our Jira ticket number as names for features, bugs or hotfix and we use the Jira Version as a Release name. This makes absolutely sense to us and makes the flow pretty transparent. We also use BitBucket to host our Git ...

C# 7: Local Functions

Die Situation kennen viele von euch: Ihr implementiert in einer Klasse eine Berechnung. Diese wird in mehrere Funktionen aufgeteilt, damit das übersichtlicher und leichter verständlich wird. Das funktioniert ganz gut, wenn jede Berechnung eine eigene Klasse erhält. Manchmal enthält sie jedoch mehrere davon (was in manchen Fällen durchaus sinnvoll sein kann). Für diesen ...

Using xUnit, MSTest or NUnit to test .NET Core libraries

MSTest was just announced to be open sourced, but was already moved to .NET Core some months ago. It seems it makes sense to write another blog post about unit testing .NET Core applications and .NET Standard libraries using .NET Core tools. In this post I'm going to use the dotnet CLI and Visual Studio Code completely. Feel free to use Visual Studio 2017 instead, if you want to and if ...

How we moved to Visual Studio 2017

Visual Studio 2017 has arrived and because of .NET Core and other goodies we wanted to switch fast to the newest release with our product OneOffixx. Company & Product Environment In our solution we use some VC projects (just for Office Development & building a .NET shim), Windows Installer XML & many C# projects for desktop or ASP.NET stuff. Our builds are scripted with CAKE (see ...

C# 7: Literale

Mit C# 7.0 können numerische und binäre Literale lesefreundlicher dargestellt werden. Dies wird durch die Unterstützung von _ als Trennzeichen innerhalb des Literals erreicht. Der eigentliche Wert bleibt dadurch unverändert. Beispiele: var foo 1_345.01; // 1234,01 var bar 0b1111_1100_1010_0000; // 61603 Viel Spaß und mehr Übersichtlichkeit beim Verwenden. The post C# ...

C# 7: Tuples

Tuples sind in .NET nicht neu, vielmehr jedoch, wie mit ihnen bisher umgegangen wird. Dieser Beitrag bringt dir das Thema näher. Was sind Tuples? Tuples stellen eine geordnete, nicht veränderbare Liste von Werten dar. Schon vor C# 7.0 gab es Tuples. Hier ein Beispiel dazu: var myTuple1 Tuple.Create string, string ("norbert", "eder"); var myTuple2 new Tuple string, string ...

out -Parameter gibt es in C# schon ewig, die Handhabe war bisher jedoch immer etwas klobig. Mit C# 7 wurden einige Änderungen vorgenommen, die eine einfachere Verwendung ermöglichen.

Using dependency injection in multiple .NET Core projects

One of my last post was about Dependency Injection (DI) in .NET Core Console Applications. Some days after that post was published, I got a question about how to use the IServiceCollection in multiple projects. In this post I'm going to try to explain, how to use the IServiceCollection in a Solution with more projects. Setup To demonstrate that, I created a Solutions with two .NET ...

ActiveRoute TagHelper

I recently read the pretty cool blog post by Ben Cull about the IsActiveRoute TagHelper: http://benjii.me/2017/01/is-active-route-tag-helper-asp-net-mvc-core/. This TagHelper adds a css class to an element, if the specified route or route parts are in the current active route. This is pretty useful, if you want to highlight an active item in a menu. Inspired by this idea, I ...

HowTo: Get User Information & Group Memberships from Active Directory via C#

I had to find a way to access all group memberships from a given Active Directory user. The problem here is, that groups may contain other groups and I needed a list of “all” applied group memberships - directly or indirectly. The “fastest” solution (without querying each group) is to use the Token-Groups attribute, which already does this magic for us. This list should contain all ...

Creating a Word document OutputFormatter in ASP.NET Core

In one of the ASP.NET Core projects we did in the last year, we created an OutputFormatter to provide a Word documents as printable reports via ASP.NET Core Web API. Well, this formatter wasn't done by me, but done by a fellow software developer Jakob Wolf at the yooapps.com. I told him to write about it, but he hadn't enough time to do it yet, so I'm going to do it for him. Maybe you know ...

BrowserLink causes an error in a new ASP.NET Core web

Using the latest bits of Visual Studio 2017 and the latest SDK of .NET Core, you will possibly get an error while starting your ASP.NET Core Web in Visual Studio 2017 or using dotnet run. In Visual Studio 2017 the browser opens on pressing F5, but with wired HTML code in the address bar. Debugging starts and stops a few seconds later.

GitHub API: Create or update files

This blogpost covers a pretty basic GitHub topic: Creating and updating content on GitHub. Of course, there are many ways to do it - e.g. you could do the full Git-ceremony and it would work with all Git hosts, but in my case I just wanted to target the offical GitHub API. Prerequisite: A GitHub User, Repo and Token To use this code you will need write access to a GitHub repository and you ...
