Build .NET for Apache Spark with VS Code in a browser

My last article explained how you can use .NET for Apache Spark together with Entity Framework to stream data to an SQL Server. There is one caveat though. You have to build Microsoft.Spark.Worker yourself.

I am really honored by the fact, that a lot of people seem to use my .NET for Apache Spark docker image to explore how C# and Apache Spark can work together, for example.

Additionally, I am getting a lot of request lately, asking whether I would be willing to share the code for creating the images.

So thanks to everyone who made this image such a success and of course you are very welcome to … more

.NET for Apache Spark docker image


My last article explained, how a .NET for Apache Spark project can be debugged in Visual Studio 2019 under Windows. I have also mentioned some limitation at the end of the article.
In this article I will extend the project a bit and demonstrate the aforementioned limitation using version 0.8.0 of my docker image for .NET for Apache Spark.
Furthermore, I will show a possible workaround that can be used, if you are running Docker and Visual Studio Code under Linux (Ubuntu 18.04).

The extended application

In order to demonstrate the issue, I have … more

Quick Tip – CIFS Verzeichnis-Freigabe in Linux verwenden

Es ist immer wieder mal notwendig, Daten zwischen Windows und Linux auszutauschen und es gibt dazu mittlerweile eine Vielzahl von Möglichkeiten.
