Around four years ago when .Net Core was in its early stages, I wrote back a Configuration provider for .net core 1.x. This has been a long time. The package did picked up very well and there were multiple downloads and a few queries as well. Many people would never know that .net core started with json project files. But since then a lot changed and my package went obsolete.

A few days back got some time and bandwidth and wised to revise the package. This would not only update the latest package but would also help me understand what changes have been done as in framework as a whole. So, my fellow countrymen let me present you the MongoDbConfiguration Provider for .net Core (😁) /s

Read on further to get the details as I explain the “simple” steps to write a custom configuration provider for .net core 3.1.

With the advent of .Net Core, web Api have become more common. Apologies to my non-dotnet background friends, but with .net hands-on, its always inclined towards .net. Coming straight to the point, be it Mobile Apps, SPAs (Single Page Applications), micro-services or name whatever, you will see REST everywhere. In background of this post, old kishore kumar songs are running, so don’t offend a bit of nostalgia 😊.

But as in most cases, everyone is so busy in implementing the APIs, many of my friends don’t ever pay attention on how an API be named. Or rather, not an API but the endpoints and methods (hate to call them methods). Well, for an API the problem there is no standard as such, but rather some best practices, that should be followed ‘ideally’. Lets discuss them one by one. Most importantly, in this post shall be talking only on the API naming. I also had OpenApi in mind, but lets leave it for another post. So lets dive in.

Journey of Dependency Injection

Asp.Net Core is one of the gems (I would say) created by Microsoft that has simplified a lot of things and provides a whole lot of things by default out of the box. It based on dot net core which provides inherent capability to run cross platform but to ease out developer life several optimizations were done to enhance productivity.

One such feature is Dependency Injection. Although lately, but Microsoft did included dependency injection as a part of the core product. I have been working Asp.Net MVC since 2010 (or 2011) and started DI with Ninject which was (or is) a wonderful project. During the time I crossed paths with Unity and Autofac during different projects, but more or less the approach remain same. Create a container system, create ‘sort of’ controller factories and then register dependencies. But during all this time one thing that remain constant was additional overhead of creating this shit. So it was a moment of joy (atleast for me) when i say this in recent versions of MVC. And most importantly it is quite stable and performs well out of the box.

Async Await is one of the best feature that has changed a lot of dynamics in the recent past, but it has created same amount confusion and chaos. Lot of bad practices, wrong usage has plagued the very usage. I have refactored a very huge WPF code with lots of out ref and reference based codebase to new pattern, on covering ~80% of it, faced a few challenges reverted back. Then after a month took the task again and completed migration.

I do receive a lot of issues in PRs around this. Based on this feeling that there would be many others who are facing such isssue, this post is more targetted from experiences. There could be log of posts and videos and shit load of resources, but I would try to write it concisely and in simple language/. Again, comments are open for discussion.

Install-Package MongoDb.Asp.ConfigurationProvider

Usage: Use the single line config to load the configuration:

builder.AddMongoDbConfiguration(“mongodb://localhost”,”ConfigDatabase”,”SettingsCollection”,”SettingType”, “SettingValue”);

 

A brief blog post on implementation and open source GIT Path shall soon follow.

In this Podcast, we plan to have a base understanding, with a short demo including the setup and and configurable alerts.

Please ignore the little not so good sound quality issues because of bad mic. will try to fix in next podcast.

The Problem

Managing the configuration data have always been troublsome. Although Microsoft did provided and also updated/upgraded a lot of options from time to time, yet it remains  a challenge most of time. Things get more critical when the configuration data we are concerned is the confidential data like connection string, smtp passwords, API keys etc becase at some point of time, they do get checked in source code or shared across other developers. In one of my prev project faced a similar issue when private key and the Code Signing certificate was accidentally checked in by a developer. The customer had to revoke the certificate which invalidated all the production builds which were deployed to end users as well.

The Solution: ConfigurationBuilder()

With ASP.net there are some pretty cool enhancements that Microsoft added especially with the Configuration Builder. Earlier whole of .net relied on System.Configuration Namespace to get the configuration data. With the current version it has been greatly re-architeced which now provides a simple key value pair from multiple sources prebuild or even custom providers (like azure or mongoDb) which we shall try out in next post.
