appsettings

I've used these two configuration files many times before, but I've never taken the time to fully understand how they really work. As most people do, I understand the basics in how to call WebConfigurationManager.AppSettings["key"] to get config values. Here are some questions I came up with: What happens when you reference a configuration value within a class library, and the library is part of a bigger solution? Does the app.config need to be copied to the output directory in order for the variables to be found? (I assume yes) Can you directly use a configuration value from an app.config in

I have an exe with an App.Config file. Now I want to create a wrapper dll around the exe in order to consume some of the functionalities. The question is how can I access the app.config property in the exe from the wrapper dll? Maybe I should be a little bit more in my questions, I have the following app.config content with the exe: <?xml version="1.0" encoding="utf-8" ?> <configuration> <appSettings> <add key="myKey" value="myValue"/> </appSettings> </configuration> The question is how to how to get "myValue" out from the wrapper dll? thanks for your solution. Actually my initial concept was

we're currently planning a larger WPF LoB application and i wonder what others think being the best practice for storing lots of UI settings e.g. Expander States Menu orders Sizing Properties etc... i don't like the idea of having dozens of stored values using the delivered SettingsProvider (i.e. App.config file) although it can be used to store it in an embedded database using a custom SettingsProvider. being able to use some kind of databinding is also a concern. Has anyone had the same problems? What did you do to store lots of ui user settings? We store the preferences file here:

Is anyone aware of a way that I can set application (or user) level settings in a .Net application that are conditional on the applications current development mode? IE: Debug/Release To be more specific, I have a url reference to my webservices held in my application settings. During release mode I would like those settings to point to http://myWebservice.MyURL.com during debug mode I would love those settings to be http://myDebuggableWebService.MyURL.com . Any ideas? I know this was asked years ago, but just in case anyone is looking for a simple and effective solution that I use. Go to

public class Bar { public static readonly string Foo = ConfigurationManager.AppSettings["Foo"]; } In the .NET Framework 4.x, I can use the ConfigurationManager.AppSettings ["Foo"] to get Foo in Webconfig ,and then I can easily get the value of Foo through Bar.Foo But in .Net core, I mustto inject options , And can not get the value of Foo through Bar.Foo Is there a method, which can be directly through the Bar.Foo to get the value of Foo ? So there are really two ways to go about this. Option 1 : Options Class You have an appsettings.json file : { "myConfiguration": { "myProperty": true } }

I am following this guide . I have a Startup in the API project that uses an appsettings.json configuration file. public class Startup { public Startup(IHostingEnvironment env) { var builder = new ConfigurationBuilder() .SetBasePath(env.ContentRootPath) .AddJsonFile("appsettings.json", optional: true, reloadOnChange: true) .AddEnvironmentVariables(); Configuration = builder.Build(); Log.Logger = new LoggerConfiguration() .Enrich.FromLogContext() .ReadFrom.Configuration(Configuration) .CreateLogger(); } The particular part I'm looking at is the env.ContentRootPath . I did some digging around
