将实体框架添加到 Azure 函数：尝试激活“Function1”时无法解析“DBContext”类型的服务

Question

我正在尝试将实体框架添加到 Azure Function 项目 (.NET 6.0)。

当前，当我运行函数时出现错误

“Microsoft.Extensions.DependencyInjection.Abstractions：在尝试激活‘Function1’时无法解析类型‘FDBContext’的服务”

套餐：

Microsoft.Azure.Functions.Extensions v1.1.0
Microsoft.EntityFrameworkCore.Relational v7.0.5
Microsoft.EntityFrameworkCore.SqlServer v7.0.5
System.Data.SqlClient  v4.8.5

Startup.cs

class Startup : FunctionsStartup
{
    public override void Configure(IFunctionsHostBuilder builder)
    {
        builder.Services.AddDbContext<FDBContext>(options =>
        {
            options.UseSqlServer("<Working connection string>");
        });
        builder.Services.AddOptions();
    }
}

FDBContext.cs

public class FDBContext : DbContext
    {
        public FDBContext(DbContextOptions<FDBContext> context) : base(context)
        {  }
    
        public DbSet<DBData> DBDatas { get; set; }
    }

Function1.cs

public class Function1
{
        private readonly FDBContext _context;
        public Function1(FDBContext context)
        {
            _context = context;
        }

        [FunctionName("Function1")]
        public async Task<IActionResult> Run(
            [HttpTrigger(AuthorizationLevel.Function, "get", "post", Route = null)] HttpRequest req)
        {
            var test = _context.DBDatas.ToList();
        }
}

错误：
