IBM Informix and EntityFrameworkCore

Walk-Through

Just recently I needed to explore how I could get IBM Informix and EntitiyFrameworkCore to work together with an existing database, and therefore decided to document my findings in this simple step-by-step walk-through.

Prerequisites

As mentioned here, the IBM® Data Server Provider for .NET IBM DB2® provider option is now the preferred Informix® provider for developing new applications.

Looking at the related site for the IBM Data Server Provider for .NET, it actually states that the former Informix specific provider (IBM.Data.Informix) is now deprecated.

IBM.Data.Informix.dll is deprecated

Although this statement actually applies to the provider for .NET, … more

The latest version of my docker image for .NET for Apache Spark tries to support direct debugging from Visual Studio 2019 and Visual Studio Code.
This is the first article of a small series that will show how this can be done on different environments (Windows and Linux), and what limitations might exist.

Test application & data

I have put together a very simple C# application, named “HelloUdf”, for demonstration purposes. It is supposed to read a JSON file (coordinates.json) that contains one coordinate string per line.
Besides reading the file, the application’s task is … more

You do want to test and debug your .NET for Apache Spark application with Visual Studio? But you don’t want to set up Apache Spark yourself?
Then read along and find out how my docker image might be able to help.

Before we dig into the details however, I specifically want to thank Devin Martin for sharing his idea about such a docker image with me!

Background

As you might be aware, you can debug your .NET for Apache Spark application directly in Visual Studio by starting the related DotnetRunner in Debug mode.

Obviously that means … more

Visual Studio Container Tools Extension (Preview)

A couple of days ago, I came across the Visual Studio Container Tools Extension (Preview) Announcement.

Using docker, this VS2019 extension promises to be very useful for container image development and debugging.

Here is my first run through, using the aspnetapp sample docker image.

Preparation

The extension can be installed directly via Visual Studio 2019, or downloaded from the marketplace, as shown below.

Once installed, you obviously need to have a running container to watch it in action. For my quick test, I’ve chosen the aspnetapp sample image from mcr.microsoft.com/dotnet/framework/samples:aspnetapp, for which I … more
