.NET Core authentication and authorisation using Auth0

I'm a big proponent of delegated authentication. It's no surprise that Broken Authentication is #2 at the OWASP top 10 latest report. It's been #2 for a very long time, which means that developers and enterprises are still getting this wrong. There are so many ways that authentication that can go wrong, that delegated authentication should be the preferred and possibly the default choice for all platforms.

Configure and use User Secrets in .NET Core 2.0 Console apps in development

Managing sensitive information and secrets in config files is something we have to deal with on a daily basis. Unfortunately, this is also something that we still get wrong.

The file that stores the secrets ends up in one of the following locations, depending …[read more]

Combining data from multiple sources in Azure Search

There …[read more]

Scaffolding DbContext and Models with EntityFramework Core 2.0 and the CLI

EF Core 2.0 has been out for a few weeks now. If you're looking at an ORM for your .NET application then EF Core should be at the top of the list of possible options. I say at the top and not the only one because depending on the project requirements, some features may be missing. For example, EF Core cut ties with .edmx so if you want to stick with the designer feature you will need to use EF6. There are other limitations so make sure you have a look at this post for API changes in 2. …[read more]
