DbProviderFactories & ODP.NET: When even Oracle can be tamed

Oracle and .NET: Tales from the dark ages Each time when I tried to load data from an Oracle database it was a pretty terrible experience.

CultureInfo.GetCultureInfo() vs. new CultureInfo() - what's the difference?

The problem The problem started with a simple code: double.TryParse("1'000", NumberStyles.Any, culture, out _) Be aware that the given culture was “DE-CH” and the Swiss use the ‘ for the separator for numbers.

.editorconfig: Sharing a common coding style in a team

Sharing Coding Styles & Conventions In a team it is really important to set coding conventions and to use a specific coding style, because it helps to maintain the code - a lot.

Did you know that you can run ASP.NET Core 2 under the full framework?

This post might be obvious for some, but I really struggled a couple of month ago and I’m not sure if a Visual Studio Update fixed the problem for me or if I was just blind… The default way: Running .NET Core AFAIK the framework dropdown in the normal Visual Studio project template selector (the first window) is not...

Windows Fall Creators Update 1709 and Docker Windows Containers

Who shrunk my Windows Docker image? We started to package our ASP.NET/WCF/Full-.NET Framework based web app into Windows Containers, which we then publish to the Docker Hub. Someday we discovered that one of our new build machines produced Windows Containers only half the size: Instead of a 8GB Docker image we only...

First steps to enable login with Microsoft or Azure AD account for your application

It is quite common these days to “Login with Facebook/Google/Twitter”. Of course Microsoft has something similar. If I remember it correctly the first version was called “Live SDK” with the possibility to login with your personal Microsoft Account. With Office 365 and the introduction of Azure AD we were able to...

Signing with SignTool.exe - don't forget the timestamp!

If you currently not touching signtool.exe at all or have nothing to do with “signing” you can just pass this blogpost, because this is more or less a stupid “Today I learned I did a mistake”-blogpost. Signing? We use authenticode code signing for our software just to prove that the installer is from us and “safe to...

Introducing Electron.NET - building Electron Desktop Apps with ASP.NET Core

The last couple of weeks I worked with my buddy Gregor Biswanger on a new project called “Electron.NET“. As you might already guess: It is some sort of bridge between the well known Electron and .NET. If you don’t know what Electron is: It helps to build desktop apps written in HTML/CSS/Javascript The idea Gregor...

dnSpy - a OSS IL decompiler and debugger

My colleague was fighting against a nasty bug, that only occures on one machine. Unfortunatly this machine was not a development machine (no VS installed) and we didn’t want to mess with VS remote debugging, because (AFAIK) his would need some additional setup but we were not allowed to install anything. Soooo… he...

IdentityServer3 with WindowsAuthentication with ASP.NET WebApi & ASP.NET & WPF App

Please note: In my sample and in this blogpost I cover IdentityServer 3, because last year when I was working on the sample and our real implementation IdentityServer4 (a rewrite of IdentityServer 3) was in beta.

How to convert .crt & .key files to a .pfx

The requirements are simple: You will need the .cer with the corresponding .key file and need to download OpenSSL. If you are using Windows without the awesome Linux Subsystem, take the latest pre-compiled version for Windows from this or this site. Otherwise with Bash on Windows you can just use OpenSSL via its...

Non-cryptographic hash functions for .NET

Creating hashs is quite common to check if content X has changed without looking at the whole content of X. Git for example uses SHA1-hashs for each commit. SHA1 itself is a pretty old cryptographic hash function, but in the case of Git there might have been better alternatives available, because the “to-be-hashed”...

Using Visual Studio Code & Team Foundation Version Control (TFVC)

Recently we start working on a Angular 4 app but all other parts of the application (e.g. the backend stuff) were stored in a good old TFVC based repository (inside a Team Foundation Server 2015) .

C#: Private Typen in ein XML serialisieren

Eigentlich ist es ja ein alter Hut (und XML ist für viele out), aber aus Gewohnheit bin ich heute selbst wieder in diese Falle getappt. Es geht um eine kleine Library, die eine möglichst kleine Schnittstelle nach außen bieten soll. Diese dient dazu, um einige Konfigurationen vornehmen zu können. Diese werden im...
