Replace SQL Server LocalDB dependency with SQLite so database integration
tests can run in CI where no SQL Server instance is available.
Changes:
- Add SqliteTestDb.cs to create/manage a temporary SQLite database with
the same schema and seed data as the original LocalDB test database
- Replace Microsoft.Data.SqlClient with Microsoft.Data.Sqlite package
- Simplify WellKnownValues.cs to serve the SQLite connection string
- Initialize/cleanup SQLite database in AssemblyInitialize/Cleanup
- Remove #if DEBUG guards and [TestCategory("SkipOnCIServer")] attributes
from SafeDataReaderTests, DataPortalTests, and DataPortalExceptionTests
- Update exception message assertions for SQLite CHECK constraint errors
- Remove MDF/LDF file copy references from project file

SQLite's SqliteConnection does not automatically enlist in ambient System.Transactions.TransactionScope the way SQL Server does. Replace the [Transactional(TransactionalTypes.TransactionScope)] attribute with an explicit SQLite transaction so the first INSERT is properly rolled back when the second INSERT fails the CHECK constraint. https://claude.ai/code/session_0123tC2ciU58UgL8jR2d5PBt
Microsoft.Data.Sqlite does not support System.Transactions.TransactionScope (EnlistTransaction throws NotSupportedException). Switch to System.Data.SQLite which properly enlists in ambient TransactionScope, so the [Transactional(TransactionalTypes.TransactionScope)] attribute test remains valid and the rollback behavior is tested end-to-end through CSLA. https://claude.ai/code/session_0123tC2ciU58UgL8jR2d5PBt

Summary
This PR migrates the CSLA test suite from using SQL Server (System.Data.SqlClient) to SQLite (Microsoft.Data.Sqlite), enabling tests to run without external database dependencies.
Key Changes
Replaced SQL Server with SQLite: Updated all test classes to use
SqliteConnectionandSqliteCommandinstead ofSqlConnectionandSqlCommandCreated SqliteTestDb utility class: New helper class that programmatically creates and manages an in-memory SQLite test database with schema and seed data mirroring the original SQL Server DataPortalTestDatabase
Updated WellKnownValues: Refactored to use the new SqliteTestDb instead of reading from app.config connection strings
Updated test infrastructure: Modified Startup.cs to initialize and cleanup the SQLite test database during assembly setup/teardown
Simplified test code: Removed verbose try-catch-finally blocks and leveraged C#
usingstatements for resource managementUpdated assertions: Modified schema validation assertions to use column names instead of ordinal indices for better maintainability
Updated exception handling: Changed expected exception types from
SqlExceptiontoSqliteExceptionUpdated CI workflow: Re-enabled test execution in GitHub Actions workflow
Project file updates: Replaced System.Data.SqlClient NuGet package reference with Microsoft.Data.Sqlite 6.0.0
