LeanDb.EntityFrameworkCore

Entity Framework Core query implementation for LeanDb. Use this package to execute LeanDb queries against any database via EF Core DbContext.

Usage

// Define a query
public record GetUserCount : IQuery<int>;

// Define its EF Core implementation
public class GetUserCountImplementation : IEfCoreQueryImplementation<AppDbContext, int>
{
    public GetUserCountImplementation(GetUserCount _) { }

    public async Task<int> Execute(AppDbContext dbContext, CancellationToken cancellationToken)
        => await dbContext.Users.CountAsync(cancellationToken);
}

// Register with DI
services.AddDbContext<AppDbContext>(options =>
    options.UseSqlServer(connectionString));

services.AddEfCoreDb<AppDbContext>(options =>
    options.LoadImplementationsFromAssembly(typeof(GetUserCountImplementation)));

// Execute
var db = serviceProvider.GetRequiredService<EfCoreDb<AppDbContext>>();
var count = await db.Execute(new GetUserCount());

How it works

  1. Define a query — create a record or class implementing IQuery<TResult>.
  2. Implement the query — create a class implementing IEfCoreQueryImplementation<TDbContext, TResult>. The implementation receives the typed TDbContext and executes the query using EF Core methods.
  3. Register — call AddEfCoreDb<TDbContext>() on your IServiceCollection, pointing to the assembly that contains your implementations.
  4. Execute — resolve EfCoreDb<TDbContext> and call Execute(query).

Registration

services.AddEfCoreDb<TDbContext>(options =>
{
    // Required: scan an assembly for query implementations
    options.LoadImplementationsFromAssembly(typeof(SomeImplementation));

    // Optional: scan additional assemblies
    options.LoadImplementationsFromAssembly(typeof(OtherImplementation));
});

The EfCoreDb<TDbContext> is registered as scoped, matching the typical lifetime of an EF Core DbContext.
