MachineMappedSettings.NetConfigFile NuGet Package

MachineMappedSettings.NetConfigFile is a .NET library that provides a simple config section similar to the appSettings config section in a .NET config file that maps settings by key and machine name which allows multiple instances of the same key to be configured with different values and machine names.

When a key is resolved, the value is returned for the specific instance that matches the key and also the local machine name on which the code is executing. This allows for machine-specific values to be returned which is especially useful for test projects executed across multiple environments.

This is a simple alternative to using XML configuration transforms.
