可以尝试使用 EF Core 来管理数据库访问并实现服务器端应用程序。

示例代码：

1. 定义数据库上下文

public class MyDbContext : DbContext
{
    public MyDbContext(DbContextOptions options) : base(options)
    {
    }

    public DbSet MyEntities { get; set; }
}

2. 注册数据库上下文和服务

public void ConfigureServices(IServiceCollection services)
{
    services.AddDbContext(options =>
    {
        options.UseSqlServer(Configuration.GetConnectionString("DefaultConnection"));
    });

    services.AddScoped();
}

3. 定义服务

public class MyService
{
    private readonly MyDbContext _dbContext;

    public MyService(MyDbContext dbContext)
    {
        _dbContext = dbContext;
    }

    public async Task GetMyEntity(Guid id)
    {
        return await _dbContext.MyEntities.FindAsync(id);
    }
}

4. 在 Razor 页面中使用服务

@page "/my-page"
@inject MyService MyService

@if (MyEntity != null)
{
    
@MyEntity.Name
}
else
{
    
Loading...
}

@code {
    private MyEntity MyEntity;

    protected override async Task OnInitializedAsync()
    {
        MyEntity = await MyService.GetMyEntity(Guid.NewGuid());
    }
}
