Question 1

How to set up FreeSql with SQLite in .NET Core?

Accepted Answer

Use the FreeSqlBuilder to configure the connection string, as shown in the quick start: 'UseConnectionString(FreeSql.DataType.Sqlite, @"Data Source=document.db")' and enable auto-sync for schema migration. Ensure the IFreeSql instance is defined as a singleton for optimal performance.

Question 2

FreeSql vs Entity Framework Core: which is better for performance?

Accepted Answer

FreeSql benchmarks in the README show competitive performance with Dapper, and it offers AOT support for optimized runtime. However, Entity Framework Core has a more mature ecosystem and tooling, so choose FreeSql for multi-database needs or AOT scenarios, and EF Core for broader community support.

Question 3

Does FreeSql support lazy loading?

Accepted Answer

Yes, FreeSql supports lazy loading through navigation properties, as mentioned in the advanced querying features. You can configure it via IncludeMany or global settings, but be mindful of performance implications in large datasets.

Question 4

How to handle transactions in FreeSql?

Accepted Answer

Use the [Transactional] attribute or UnitOfWorkManager, as referenced in the Repository section. This allows for multiple transaction propagation in ASP.NET Core, ensuring data consistency in complex operations.

Question 5

Is FreeSql good for database migrations?

Accepted Answer

Yes, FreeSql supports both CodeFirst (synchronizing entity structure to the database) and DbFirst (generating entities from existing databases), with tools available for schema management. However, it may require more manual setup compared to EF Core's integrated migrations.

Question 6

Can FreeSql work with read/write separation?

Accepted Answer

Absolutely, FreeSql provides built-in read/write separation features, documented in the wiki. You can configure multiple database connections for scaling reads and writes, but it requires additional setup in the connection strings and options.
