To install the minimum requirements:

Install-Package Axolotl

To install support for serialization, AutoFixture, EF Core, Model Binding, or Dapper select the lines that apply:

Install-Package Axolotl
Install-Package Axolotl.Http
Install-Package Axolotl.EFCore
Install-Package Axolotl.AspNet
Install-Package Axolotl.Razor

Asp.Net Core Samples

Added required packages

Install-Package Axolotl
Install-Package Axolotl.EFCore
Install-Package Axolotl.AspNet

Add sample entity

public sealed class Post : AuditableEntity<Guid> {
    public string Title { get; set; } = null!;
    public Category Category { get; set; } = null!;
    public ICollection<Tag> Tags { get; set; } = null!;
}

Add to context

public class ServiceContext : DbContext {
    public ServiceContext(DbContextOptions<ServiceContext> options) : base(options) { }
    protected override void OnModelCreating(ModelBuilder modelBuilder) { }
    
    public virtual DbSet<Post> Posts { get; set; } = null!;
    
}

Create your generic repository and apply DbContext

public class GenericRepository<TEntity, TKey> : GenericBaseRepository<TEntity, ServiceContext, TKey> 
    where TEntity : class, IAggregateRoot, IHasKey<TKey> 
    where TKey : notnull {
    public GenericRepository(ServiceContext context) : base(context) { }
}

Register generic repository

builder.Services.RegisterGenericRepositories(typeof(GenericRepository<,>));
builder.Services.RegisterGenericServices();

Create optional filter specification

public sealed class CategorySpec : Specification<Post, Guid> {
    public CategorySpec(IPageFilter filter) {
        var search = filter.Search ?? string.Empty;
        var text = search.ToLower().Split(" ").ToList().Select(x => x);
        Query.Where(x =>  x.Title != String.Empty && x.Title.Length > 3 && text.Any(p => EF.Functions.Like(x.Title.ToLower(), $"%" + p + "%")))
            .AsNoTracking()
            .OrderBy(b => b.Title);
    }
}

Create feature/endpoint

public class CategoryFeature : GenericFeature<CategoryFeature, Guid> {
    public override IEndpointRouteBuilder MapEndpoints(IEndpointRouteBuilder endpoints) {
        var state = new FeatureState(new List<RouteState> {
            new (RouteType.GetAll, typeof(CategorySpec)),
            new (RouteType.GetById),
            new (RouteType.Create)
        });

        return SetupGroup<CategoryFeature, Category, Guid>(endpoints, state);
    }
}
