I write about the difficulties and methods I have found while developing this site with ASP.NET Core 2.2, upgrading to ASP.NET Core 3.1 then to ASP.NET Core 5.0 using EntityFramework Core. None of the authors, contributors, or anyone else connected with KenHaggerty.Com, in any way whatsoever, can be responsible for your use of the information contained in or linked from these articles.

All articles have created and last updated dates. I will do my best to update any article which I learn to be inaccurate. The research comes from articles and posts on sites like stackoverflow, docs.microsoft.com and GitHub. I hardly ever find my solution from one article or post. I give references in the article to the most pertinent sources. There is a comments feature to allow open discussion. If you have concerns and do not want to register, please send me an email.
