.env file does not load in ASP.NET / .NET Framework 4.7.2

[MrDave1999]

I am testing this library in ASP.NET with .NET Framework 4.7.2 but the result is unexpected. The Load method always generates the same error:

.env: error: No such file or directory.

The problem is that this library uses the Directory.GetCurrentDirectory() method and this method is returning a path that does not correspond to the project path:

C:\Program Files\IIS Express

This problem has been mentioned here: dotnet/aspnetcore#4206.
As far as I can see, the Directory.GetCurrentDirectory() method works perfectly when you use it with .NET Framework 4.7.2, however, with ASP.NET it returns a path that does not correspond to the current directory of the application.

Temporary solution

The temporary solution I found was to use the AppContext.BaseDirectory property:

new EnvLoader()
     .SetBasePath(System.AppContext.BaseDirectory)
     .Load();

Note: This solution only works with dotenv.core >= 2.0.0.

The value representing the AppContext.BaseDirectory property is null in xamarin-android. This bug has not been fixed yet: dotnet/android#3489.

Note that the AppContext.BaseDirectory property returns the root directory of the project in ASP.NET Framework, on the other hand, in ASP.NET Core it returns the current directory of the application.
