  • Tools & Utilities
ASP.NET is a framework for building and running modern, internet-connected web apps, IoT apps, and mobile backends. Its open-source, cross-platform implementation, ASP.NET Core, runs on the .NET runtime so developers can host high-performance web services and APIs on their own server.

Health score?A 0-100 score computed nightly from four factors: maintained (40%: recent commits and steady activity), popular (25%: GitHub stars, log scale), easy to install (20%: platforms, install notes, setup guides, Docker image) and light to run (15%: minimum RAM, ARM support). When the source code has been checked, a fifth factor, security check (20%: automated scan for committed secrets, unsafe desktop-app settings, known-vulnerable dependencies and project hygiene; any serious finding caps it at 20), is added. Factors without data are left out and the rest are rescaled.

First-install notes

  • Keep secrets out of shared config If you set appSettings or connectionStrings, put real passwords and connection details in user secrets or a private file, not in the app config you share. If they are committed to source control, anyone who sees the code can get your credentials. source

Common questions

Do I need IIS to self-host an ASP.NET Core app?

No. In modern ASP.NET Core, self-hosting means running the app in its own process using the .NET Generic Host and built-in Kestrel web server.

Can I publish so the .NET runtime is included with the app?

You can publish the site in self-contained mode, which includes the .NET 7 framework as part of the release. Many ASP.NET hosts already support .NET 5+.

How should I store connection strings or passwords for a self-hosted ASP.NET app?

Keep real passwords and connection details out of the shared app config. Put them in user secrets or a private file instead, because committed config files can expose credentials.

What should I set up after publishing the app to the server?

Deploy the published app to a folder on the hosting server. Set up a process manager that starts the app when requests arrive and restarts it after a crash or server reboot.
