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 important and doesn’t matter anyway for .NET Core related projects. ...

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 got a 4GB Docker image. Yeah, right? The problem with Windows ...

WCF Global Fault Contracts

If you are still using WCF you might have stumbled upon this problem: WCF allows you to throw certain Faults in your operation, but unfortunatly it is a bit awkward to configure if you want “Global Fault Contracts”. With this solution here it should be pretty easy to get “Global Faults”: Define the Fault on the Server Side: Let’s say we want to throw the following fault in all our ...

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 build an application to sign-in with a personal account via the ...

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 use”, otherwise you might see a big warning from Windows that the ...

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 asked me a while ago if it is possible to build desktop apps with ASP.NET ...

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 searched around and found this: dnSpy - a .NET assembly editor, ...

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. My guess is, that most stuff should still apply even if you are using IdentityServer4, but I didn’t test it. Also: I’m not a security expert - this might be all wrong, but ...

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 “native” environment. Thanks for the hint @kapsiR After the download ...

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” content is not crypto relevant - it’s just content marker. Well… in ...

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) . Unfortunately building an Angular app with the full blown Visual Studio with the “default” Team Explorer workflow is not really practical. Another point for using Visual Studio Code was ...

.NET CultureInfo in Windows 10

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 ...

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 ...

Be aware that all our tests have the suffix “Tests” in the project name. The files are organized like this, so we have all “Tests” in a “tests” folder and the actual code under “src”: ...

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 ...

If you stick with a github.io domain SSL is not a problem. Cloudflare to the rescure I decided to take a deeper look at Cloudflare, which provides DNS, CDN and ...

Writing loops in T-SQL

The topic is quite old, but I found it really helpful, so be warned. Scenario: Iterate over a result set and insert it in a new table in T-SQL I had to write a SQL migration script to move date from an old table into a new table with a new primary key. Update! I discovered that my problem would have been solved with a much simpler SQL script (INSERT INTO x …(SELECT … FROM Y)). So my example here ...
