Setting Up a Self-Hosted ASP.NET Core Web API with Kestrel Using HTTPS
Transitioning from an old WCF service to an ASP.NET Core Web API can be challenging, especially when ensuring secure access through HTTPS. If you're grappling with the intricacies of self-hosting your API using Kestrel and getting HTTPS to work, you're not alone. In this guide, we’ll break down the solution to some common issues encountered during this process, including configuring HTTPS endpoints with the proper setup.
The Problem Breakdown
You’ve successfully set up an ASP.NET Core Web API but run into a hurdle with HTTPS. While you can access your API via HTTP, transitioning to HTTPS yields a 500 error, which can feel frustrating. The issues may stem from an incorrectly configured certificate, or possibly a missing HTTPS endpoint.
Solution Overview
1. Understanding Kestrel Configuration
Kestrel is a powerful cross-platform web server for ASP.NET Core that requires proper configuration to handle HTTPS requests. Here’s a simplified explanation of how to configure Kestrel for self-hosting your Web API.
2. Setting Up HTTPS in Kestrel
To ensure your API can handle HTTPS requests, follow these steps:
Step 1: Configure Kestrel to Use HTTPS
You need to specify an HTTPS endpoint in your Kestrel configuration. Update your CreateWebHostBuilder method like this:

Ensure you replace "{absolute path}" with the path to your SSL certificate and "{password}" with the certificate password.
Step 2: Adding Endpoints for HTTPS
After confirming the Kestrel settings, you should configure your middleware to handle HTTPS requests. Within your Configure method in the Startup class, add the following endpoint configuration:

This addition allows your application to listen for HTTPS traffic specifically and incorporates security in the binding configuration.
3. Configuring Services for HTTPS Redirection
Next, ensure that your services are set up to handle HTTPS redirection correctly. Update your ConfigureServices method as follows:

Conclusion
Transitioning to a self-hosted ASP.NET Core Web API using Kestrel with HTTPS doesn't have to be a daunting task. By following the steps outlined above, you can successfully configure your API to handle secure connections, ensuring optimal functionality and safety.
