Environment Variables in ASP.NET Core

In my last post, I covered how to handle sensitive configuration data by using User Secrets while working in development or on your local machine.  The next step is how to use environment variables in ASP.NET Core once you deploy to production (eg Azure App Service)?

Things like my DocumentDB Auth Key, Google OAuth ClientId & Secret, Twilio Auth Token, etc. Depending on your context you may not want to be storing these types of application settings in configuration files that are committed to source control.

If you are used to using appSettings from the app.config… Read More »Sensitive Configuration Data in ASP.NET Core

This project isn’t doing anything complicated but does contain enough real world use cases that can give me an idea of how the API works. Concurrency The first thing I needed to implement was how to handle concurrency.  Specifically optimistic concurrency. In an optimistic concurrency model, a violation is considered to have occurred if, after a user receives a value from the database, another user modifies the value before the first user has attempted to modify it.… Read More »Optimistic Concurrency in Azure Cosmos DB
