ASP.NET MVC Interview Questions
Shares a framework for interviewing ASP.NET MVC developers around five topics: MVC separation of concerns, dependency injection tradeoffs, Razor versus SPA rendering, authentication/CSRF handling, and MVC/Web API/Core differences.

Enrich ELMAH errors using error filtering hook
Shows how to enrich classic ELMAH errors with custom data, like a database username, by hooking the ErrorLog_Filtering event in Global.asax.cs.

Set up SSL on GitHub Pages with custom domain using Azure

One versioning scheme to rule them all
Explains elmah.io's client library versioning scheme: the major version now tracks the API version, so Elmah.Io.Client 3.0.42 targets API v3, and dependent packages like ELMAH and log4net integrations follow suit. Packages previously at 1.x.x were bumped to 3.0.x; Logary keeps its own numbering. ...
