# Config

### Purpose
This module provides centralized access to a custom application configuration file, abstracting away the details of `System.Configuration`. It exists to allow the application to read settings from a non-default config file path defined by `DataProConstants.CustomConfigPath`, enabling configuration separation from the main executable.

### Public Interface

**`DataProConfig` (static class)**
- `static Configuration AltConfig { get; }` — Returns the `Configuration` object mapped to the custom config file. Useful for advanced configuration operations not covered by helper methods.
- `static string GetAppSetting(string key)` — Retrieves an application setting value by key from the `<appSettings>` section. Returns `String.Empty` if the key is not found.
- `static object GetSection(string sectionName)` — Retrieves a named configuration section from the config file. Used by plugin code to access custom sections.

### Invariants
- The static constructor runs exactly once, before any member is accessed.
- `Config` is initialized via `ConfigurationManager.OpenMappedExeConfiguration` with `ConfigurationUserLevel.None` and will never be null after static construction.
- `GetAppSetting` always returns a non-null string (empty string if key missing).
- The configuration file path is determined by `DataProConstants.CustomConfigPath` and cannot be changed at runtime.

### Dependencies
- **Depends on**: `System.Configuration`, `DataProConstants` (specifically `DataProConstants.CustomConfigPath`).
- **Depended on by**: Unknown from source alone—likely consumed by plugin code and core application components requiring configuration access.

### Gotchas
- If `DataProConstants.CustomConfigPath` points to a non-existent or malformed config file, the static constructor will throw an exception, rendering the entire class unusable for the application lifetime.
- `GetAppSetting` performs a linear search through `Config.AppSettings.Settings` using LINQ; performance may degrade with very large numbers of settings.
- The third parameter `true` passed to `OpenMappedExeConfiguration` is undocumented in the source context—it appears to be a boolean for "preload" behavior, but its exact effect is unclear from source alone.
