Using pictures in ASP.NET Core MVC is not always very straightforward. A lot of articles you find simply upload the pictures to a www-folder and use them from there. This may work if you host your own website. This approach will give problems when using a cloud service. A cloud service may terminate your deployed version and may spin up a new fresh version to replace the old one. All pictures uploaded to the www-folder will then be lost and your database will have references to resources on the file system that do not exist anymore. In this post, I will show you how to store the images in your database and use them from there. The code for this blog post can be found here .

I deliberately don't pay attention to the layout of the site, because it will only distract you from the meaningful code.  I have created a regular ASP.NET Core MVC 6 application using the templates available in Visual Studio 2022....

If you are building a modern web application, you will often need a frontend and a web API. I always want to keep these projects apart to maintain separation of concerns but to enable easy code sharing and developer focus, I also like to keep the projects in one solution. I love to use Azure DevOps for my CI/CD work, so I want to deploy these artifacts with one pipeline. In this post, I will show you, how you can do this. I do expect some basic knowledge about setting up a build and release pipeline in Azure DevOps. Visual Studio Solution For this blog post, I created the following solution. The solution contains a web application and a WebAPI. Both projects share the Domain class library. Build pipeline The solution can be built with the classic workflow or using the new yaml templates. For this post, I use the classic editor with the template for ASP.NET Core. The default settings for the build can be used. By default, all projects will be built and all p...

On January 26 2019 I will give a session about getting started with Blazor at DOTNED Saturday ( https://dotnedsaturday.nl/sessions/inleiding-in-blazor/ ). The session will be in Dutch.

The last few years I have been teaching children to program. Next week I will give a lecture at a school about Prezi. It is fun to have to opportunity to educate our children.

Today I had the opportunity to organise a programming with your kids event for Bergler. It was fun to see the chidren play with Scratch, Code.org and the Microbit.

Today I submitted a few talks for .NET Saturday on January 27th 2018 in The Netherlands. You can already register to attend this day ( www.dotned.nl/dotned-bijeenkomst/dotned-saturday/?id=133 ). I hope I will be selected to give a talk.

I just took some time during the holidays to install Visual Studio 2017 RC. The initial setup changed a lot. You can easily choose what kind of development you are planning to do. It definitely is an improvement to the previous versions.
