# Properties
|

|

|

|
|
### Purpose
|
||
|
|
This module provides assembly metadata and application-scoped configuration settings for the `LocalSQLDB` custom installer action. It exists to configure file paths, extensions, and registry keys related to local SQL Database deployment for the DataPRO application. The settings support the installer's ability to locate and configure local database files during installation.
|
||
|
|
|
||
|
|
### Public Interface
|
||
|
|
- **`Settings` class** (internal sealed, partial) - Auto-generated settings class inheriting from `System.Configuration.ApplicationSettingsBase`.
|
||
|
|
- `static Settings Default { get; }` - Returns the synchronized singleton instance of settings.
|
||
|
|
- `string RegistryDataPROExe { get; }` - Returns `"DataPRO.exe"`. Application-scoped setting.
|
||
|
|
- `string ApplicationSettings { get; }` - Returns `"applicationSettings"`. Application-scoped setting.
|
||
|
|
- `string LocalDbFolder { get; }` - Returns `"db"`. Application-scoped setting.
|
||
|
|
- `string Mdf { get; }` - Returns `".mdf"`. SQL Server primary database file extension. Application-scoped setting.
|
||
|
|
- `string LogLdf { get; }` - Returns `"_log.ldf"`. SQL Server log file suffix/extension. Application-scoped setting.
|
||
|
|
- `string DataPRO { get; }` - Returns `"DataPRO"`. Application-scoped setting.
|
||
|
|
|
||
|
|
### Invariants
|
||
|
|
- All settings are application-scoped and read-only at runtime.
|
||
|
|
- File extension settings (`Mdf`, `LogLdf`) must include the leading dot where appropriate (`.mdf` does, `_log.ldf` includes prefix).
|
||
|
|
|
||
|
|
### Dependencies
|
||
|
|
- **Depends on**: `System.Configuration.ApplicationSettingsBase`, `System.Runtime.CompilerServices`, `System.Runtime.InteropServices`.
|
||
|
|
- **Depended on by**: The parent `LocalSQLDB` installer custom action module (inferred from namespace).
|
||
|
|
|
||
|
|
### Gotchas
|
||
|
|
- The `LogLdf` setting value is `"_log.ldf"` which includes a prefix underscore, not just the extension. This suggests it's meant to be appended to a database name, not just a pure extension.
|
||
|
|
- The `RegistryDataPROExe` setting name suggests registry usage, but the value is just a filename without a path.
