Documentation: DatabaseUnitTesting.Properties.Settings

1. Purpose

This module is an auto-generated settings class that provides strongly-typed access to application configuration values for the DatabaseUnitTesting project. It exists to centralize configuration management for database unit testing, specifically storing connection parameters, database names, and snapshot identifiers. The class is generated by Visual Studio's SettingsSingleFileGenerator tool and serves as the configuration layer between the unit test code and the underlying .settings file.

2. Public Interface

`Settings` (sealed partial class)

Inherits from: global::System.Configuration.ApplicationSettingsBase

Member	Signature	Scope	Description
`Default`	`public static Settings Default { get; }`	Static	Returns the singleton default instance of the `Settings` class, synchronized for thread-safe access.
`ConnectionString`	`public string ConnectionString { get; }`	Application-scoped	Returns the database connection string for the unit test database. Read-only. Default value points to `FAJITA\DEV_SQL` server with `DataPRO_UnitTest` catalog.
`DBName`	`public string DBName { get; set; }`	User-scoped	Gets or sets the database name. Default value is `"DataPRO_UnitTest"`.
`DBSnapshot`	`public string DBSnapshot { get; set; }`	User-scoped	Gets or sets the database snapshot name. Default value is `"DataPRO_UnitTestSnapshot"`.

3. Invariants

Auto-generated constraint: This file is machine-generated by Microsoft.VisualStudio.Editors.SettingsDesigner.SettingsSingleFileGenerator version 17.10.0.0. Manual modifications will be lost upon regeneration.
Singleton pattern: The defaultInstance field is created once via Synchronized() and returned through the Default property.
Scope immutability: ConnectionString is application-scoped (read-only at runtime); DBName and DBSnapshot are user-scoped (read/write).
Type safety: All settings are typed as string; accessors perform explicit casts from the underlying settings dictionary.

4. Dependencies

This module depends on:

System.Configuration.ApplicationSettingsBase - Base class providing settings management infrastructure
System.Configuration.ApplicationScopedSettingAttribute - Attribute for application-level settings
System.Configuration.UserScopedSettingAttribute - Attribute for user-level settings
System.Configuration.SpecialSettingAttribute - Marks ConnectionString as a special connection string type
System.Configuration.DefaultSettingValueAttribute - Provides default values for each setting
System.Runtime.CompilerServices.CompilerGeneratedAttribute - Indicates tool-generated code
System.CodeDom.Compiler.GeneratedCodeAttribute - Metadata about the code generator

What depends on this module:

Inferred: Any code within the DatabaseUnitTesting project that accesses configuration values via Settings.Default.

5. Gotchas

Hardcoded credentials in source control: The ConnectionString default value contains a plaintext SQL Server sa password (!!QQAAZZxxssww22). This is a significant security risk and should be moved to a secure configuration mechanism (e.g
