Best way to get application folder path

Question

I see that there are some ways to get the application folder path:

1. Application.StartupPath
2. System.IO.Path.GetDirectoryName( System.

Answer 1

In my experience, the best way is a combination of these.

1. System.Reflection.Assembly.GetExecutingAssembly().GetName().CodeBase Will give you the bin folder
2. Directory.GetCurrentDirectory() Works fine on .Net Core but not .Net and will give you the root directory of the project
3. System.AppContext.BaseDirectory and AppDomain.CurrentDomain.BaseDirectory Works fine in .Net but not .Net core and will give you the root directory of the project

In a class library that is supposed to target.Net and .Net core I check which framework is hosting the library and pick one or the other.
