NuGet Badge is a zero-dependency module that loads environment variables from a .env environment variable file into System.Environment.



First install the library as a dependency in your application from nuget



dotnet add package

or for paket

paket add

Create a file with no filename and an extension of .env.

A sample .env file would look like this:


in the Startup.cs file or as early as possible in your code add the following:




At times the .env would not be in the same directory as your assembly, in that case the following would apply



var success = DotEnv.AutoConfig();
  // env successfully found and read

this looks through your assembly's folder and three folders up for a .env file and loads that.

the values saved in your .env file would be availale in your application and can be accessed via:

Environment.GetEnvironmentVariable("DB_HOST"); // would output 'localhost'
