ASP.NETCore2.1中的UseSqlite与EntityFrameworkCore无法正常工作

我正在ASP.NET Core 2.1中启动一个Razor页面项目.我正在尝试使用SQLite,但在配置数据库时,只有SQL Server似乎是一个选项.

Startup.cs

using Microsoft.AspNetCore.Builder;
using Microsoft.AspNetCore.Hosting;
using Microsoft.AspNetCore.Mvc;
using Microsoft.Extensions.Configuration;
using Microsoft.Extensions.DependencyInjection;
using Application.Models;
using Microsoft.EntityFrameworkCore;

namespace Application
{
    public class Startup
    {
        public Startup(IConfiguration configuration)
        {
            COnfiguration= configuration;
        }

        public IConfiguration Configuration { get; }

        // This method gets called by the runtime. Use this method to add services to the container.
        public void ConfigureServices(IServiceCollection services)
        {
            services.AddDbContext(optiOns=>
               options.UseSqlite("Data Source=Database.db"));
            services.AddMvc().SetCompatibilityVersion(CompatibilityVersion.Version_2_1);
        }

        // This method gets called by the runtime. Use this method to configure the HTTP request pipeline.
        public void Configure(IApplicationBuilder app, IHostingEnvironment env)
        {
            app.UseStaticFiles();
            app.UseMvc();
        }
    }
}

Intellisense无法识别options.UseSqlite和构建失败.对于.net核心2.0项目,这不是/不是问题.

这不支持吗？阅读文档使它看起来像是.我不确定这里还有什么问题.

您似乎尚未将Microsoft.EntityFrameworkCore.Sqlite安装到项目中.
