Hi Oleg Sviridov "....and add appsettings.json file to the project." How? RMB on EmploymentManagement->Add->New Item->ASP.NET Core->JSON file/JSON schema File ??? Then add the following?.... { "Logging": { "LogLevel": { "Default": "Warning" } } } ...save all and run the project? does the appsettings.developement.json get built automatically or do you need to add that separately??? If so, how? and how does it associate itself to the appsettings.json??? Regards

Hi kudvenkat, The development example.... { "Logging": {"LogLevel": {"Default": "Debug", "System": "Information", "Microsoft": "Information"} }, "Mykey": "Value of MyKey from appsettings.Development.json" } ....doesn't show, just the appsettings.json example... { "Logging": { "LogLevel": { "Default": "Warning" } }, "AllowedHosts": "*", "Mykey": "Value of MyKey from appsettings.json" } ....though the... "Mykey": "Value of MyKey from Environmrnt Variable" ...version in the launchSettings.json did display........once I stopped running it the profile context of "EmployeeManagement" and ran it in "IIS Express" rpofile context I'd added it to!!!

It Worked Thank's Sir

Yes good idea

Did you find anything?

right-click project -> Add -> new item -> App Setting file -> Add and it will generate the file for you.

Excellent Sir, Great Help, Very good explanation..

Yes we can use for that have connection string in dev json file and under env.isdevelopment condition, you can access the connection string.

RE: I am new to development, and dot net is my first language can anyone tell me what is the exact significance of appconfig file ? - An "app.config" file is the traditional configuration file used for applications built using the full .NET framework. It is built in an XML format and can contain a variety of settings (e.g. key/value pairs, service endpoint definitions, connection strings, framework specific settings, etc.). Note that in traditional ASP.NET this file is named "web.config" and can be altered post deployment using tools in Internet Information Services (IIS) server manager. These files can get rather large and complex as services and additional libraries are added to the application. App.config/Web.Config files are required to run applications using the full .NET framework. - The appsetting.json file in .NET Core is built in a JSON (JavaScript Object Notation) format and appears to be an optional component. The .NET Core dependency injection container (implemented in the Microsoft.Extensions.DependencyInjection) is able to search for different configuration sources (e.g. appsettings.json, appsettings.development.json, launchSetting.json, system environment variables, application parameters, etc) and bundle them into a single object that can be accessed at run time via a strongly typed object. RE: I see in this video the value is stored using key/value pair but in realtime project what exactly will it store ? - What the file is storing during "realtime"/run time may depend on what environment you are running the application under. In most circumstances it will probably contain at least connection string to a database. The connection string would probably be targeting different database servers when running in a production environment as opposed to a development environment.

You need to put configuration IIS Express in Profiles in json file if you are launching using IIS Express.

@@mohinimadavi5870 Thank you

maybe You are using dotnet core 2.1

Yes, it does I'm using the same

If anyone else is confused by this then you need to add the key to the relevant profile if not running via IISExpress - the environment variables are specific to a profile.

Yes, make sure to which profile you're adding environment variable
