Hey Friends, The .NET Framework, through configuration files, gives developers and administrators control and flexibility over the way applications run. Developers can put settings in configuration files, eliminating the need to recompile an application every time a setting changes. Configuration in ASP NET is performed using one or more configuration providers. Configuration providers read configuration data from key-values using a variety of config sources.
In this video, let's take a deep dive into how to configure values in ASP NET Core, read it in your application, how the default configuration providers are set up and how to write customer configuration providers.

No one covered Configuration is such a detail with example in you tube! your videos will be my first reference point when it comes to these topics before Microsoft releases new version! i can't stop appreciate your content and your method of teaching! Salute!👏👏👏

Your approach in these videos is probably the most straight forward/to the point explanations I have yet to see. Definitely getting a sub, extremely good content. Helped me get up to speed on a few things new to me at a new job. I would love to see you build a simple Crud Api, tie it into a db maybe Mongo, then build a Spa with react that uses that Api, maybe tie in docker then deploy Azure. That be a good "Here's pretty much all the things you need to know" video for folks new to C#.Net. Thanks for the Awesome content!

Hi @RahulNath. Great job with the high quality content. Your .NET videos are the best. However it would be nice if you could make the same videos that you have in this series for .NET 6.0. I understood the .NET 3.1 configuration. But stillconfused on .NET 6.0, as there is no startup class there. Thanks and appreciate the hard work!

@RahulNath Год назад

Glad you like these videos and the series bit.ly/asp-net-core-series I will do a follow up video, but nothing much has changed that actually. It's only that the Startup.cs is now moved into the Program.cs. All the other functionality still holds the same. Are you facing any issues with any of the code?

Thank you for super vid lesson. You have shown in-memory implementation at last. Actually any cloud native or modernization app should not use sticky session storage at application level so, Can we use above in-memory implementation for (for small data pushing and retrieving) pushing data at one action method of a controller and then retrieving that data another action method of an another controller(replacement of session storage)? Many Thanks,

Hi, I wanna to ask about this config. Let's say, I already publish this project into my local PC folder. My setting file have included the database IP, but maybe I want change the setting file IP in the future. When I running the project, the setting still based on the previous IP instead of new IP. How can I solve this issues?

@RahulNath 3 года назад

You can update it in the appsettings.json and it will automatically pick it up, since it is configured to reload on file change. If you are deploying to a Cloud Environment you can use Azure App Configuration to dynamically change configuration values ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-VEjYW14WKRM.html Let me know if that answers your question.

@rajendrank9582 3 года назад

Is there any way we can reload the configuration without going to appsetting.json. for example, logging is set to warning in appsettings.json and I want to change to trace for some time like I need verbose for some reason. Can I achieve this without modifying the appsettings.json?

@RahulNath 3 года назад

How do you intend to achieve this? What would trigger the change, would it be an endpoint in the application or some event within the application code, without manual intervention? This Github issue talks about something similar and has some inputs github.com/dotnet/AspNetCore.Docs/issues/15698 Let know if that helps.

@@RahulNath Trigger can be an endpoint response value, and using an IHostedService I can keep polling to this endpoint and the moment value returned as 'Verbose' for example I need to set the entire logging level to 'Trace', ya definitely without manual intervention. Currently what I did was setting values in appsettign.json to the desired value through reading and writing the json file. So I looking for a alternative.

i am creating Multi tenant application .in that every tenant have different database. i want to set database connection string in memory for each tenet. and if i update connection string in database it will aslo update in memory. please help me. but i dont want to use entity framework

@RahulNath 3 года назад

Not sure if I understand your question fully. Where do you want to save your configuration? Is it in the configuration file or in a 'master database' (not specific to tenant)? You can write a custom configuration source like shown here code-maze.com/aspnet-configuration-creating-custom-provider/, if it is in a database that you want to store it and refresh it. Alternatively you can keep the connection strings in a centralized vault like Key Vault and fetch it from there and keep it in you app memory and autoamtically refresh it.

@uchitesting 2 года назад

Hi. I do that now that we have .NET 6. There are differences in both how to code and results. There is no more Startup.cs and its content got moved to Program.cs. There is no more Configure or ConfigureServices methods. There is no IConfiguration injected in the constructor neither. So I did search a bit to check how to do. Both builder and app identifiers have a Configuration property. Console.WriteLine($"MyKey from builder => {builder.Configuration["MyKey"]}"); Console.WriteLine($"MyKey from app => {app.Configuration["MyKey"]}");
