GitHub Actions and multi-project solutions

August 26th 2022 GitHub ASP.NET Core Azure

GitHub Actions can be a good choice for deploying an ASP.NET Core application to an Azure Web App Service if you have the code in a GitHub repository. You can even generate the GitHub Actions workflow directly from the Azure Portal. However, if your solution is not very simple, the generated workflow may not work correctly.

Unit testing ASP.NET Core Web API

August 5th 2022 ASP.NET Core Unit Testing

In a previous blog post, I looked at integration testing of ASP.NET Core Web APIs. But often unit tests make more sense. So instead of checking the already serialized responses from the REST service, you would check the value returned by the controller action method before it is serialized into an HTTP response by the ASP.NET Core runtime.

ASP.NET Core nullable route params in Swagger

July 22nd 2022 Swagger ASP.NET Core

I recently had an issue with optional route parameters in ASP.NET Core Web API not showing as such in the Open API specification generated by Swashbuckle. The most comprehensive source of information I could find on this issue was a blog post, which I used as a basis for further research.

Truncated JSON response from web API

November 5th 2021 ASP.NET Core Serialization

Web API testing in ASP.NET Core

ASP.NET Core provides great support for integration testing of Web APIs. You can host the server in the test process and still make requests over HTTP. However, if your app reads its configuration from the appsetting.json file, you'll quickly find that the test server cannot find your regular configuration file.

Custom Data in Braintree Hosted Fields

March 3rd 2017 Braintree ASP.NET Core

Braintree's Hosted Fields offering is a great compromise between payment form customization and PCI SAQ A compliance requirements. Although it is not immediately evident from the documentation, the payment form can also easily be extended with custom data fields that your business might require. This post demonstrates how to do it in an ASP.NET Core application.

Deploying ASP.NET Core RC1 Application to IIS

February 14th 2016 ASP.NET Core IIS Visual Studio

If you're used to the old ASP.NET, it's not all that obvious how to deploy an ASP.NET Core application to IIS. Although, there is documentation available for the process, I still struggled a bit, before I got everything working. This post contains the steps I had to take, so that I can simply follow them the next time. At least, until something changes again with one of the future releases.
