Динамический сводный список в Linq C #

Question

У меня есть три таблицы Product, Location, StockLocation. Я хочу, чтобы данные отображались в виде столбца, а местоположение должно быть динамическим:

Я хочу заполнить данные в моем ядре asp.netAPI-приложение, использующее ядро ​​Entity Framework и показывающее его в моем проекте Angular 7. Если это возможно в любой клиентской библиотеке с открытым исходным кодом, предложите мне.

SQL - это:

CREATE TABLE [Product](
    [ProductId] [int] IDENTITY(1,1) PRIMARY KEY NOT NULL,
    [ProductName] [varchar](250) NOT NULL,
    [Description] [nvarchar](500) NULL,
    [Code] [varchar](50) NULL,
    [SalesPrice] [decimal](18, 0) NULL
) 
GO


CREATE TABLE [Location](
    [LocationId] [int] IDENTITY(1,1) PRIMARY KEY NOT NULL,
    [LocationName] [varchar](50) NOT NULL
)

GO
CREATE TABLE [StockLocation](
    [StockId] [bigint] IDENTITY(1,1) NOT NULL,
    [StockProductId] [int] NOT NULL,
    [StockLocationId] [int] NOT NULL,
    [TotalQuantity] [decimal](18, 0) NOT NULL,
 CONSTRAINT [PK_StockLocation] PRIMARY KEY CLUSTERED 
(
    [StockId] ASC
)WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY]
) ON [PRIMARY]
GO

ALTER TABLE [dbo].[StockLocation]  WITH CHECK ADD  CONSTRAINT [FK_StockLocation_Location] FOREIGN KEY([StockLocationId])
REFERENCES [dbo].[Location] ([LocationId])
GO

ALTER TABLE [dbo].[StockLocation] CHECK CONSTRAINT [FK_StockLocation_Location]
GO

ALTER TABLE [dbo].[StockLocation]  WITH CHECK ADD  CONSTRAINT [FK_StockLocation_Product] FOREIGN KEY([StockProductId])
REFERENCES [dbo].[Product] ([ProductId])
GO
