“RouteHandlerBuilder”不包含“WithOpenApi”的定义

Question

我正在查看此文档：https://learn.microsoft.com/en-us/azure/azure-sql/database/azure-sql-dotnet-entity-framework-core-quickstart?view=azuresql&tabs=visual -studio%2Cservice-connector%2Cportal

存在问题的具体片段：

app.MapGet("/Person", (PersonDbContext context) =>
{
    return context.Person.ToList();
})
.WithName("GetPersons")
.WithOpenApi();

app.MapPost("/Person", (Person person, PersonDbContext context) =>
{
    context.Add(person);
    context.SaveChanges();
})
.WithName("CreatePerson")
.WithOpenApi();

我想将 azure sql server 连接到我的项目。我启动了 React + .Net 项目，这些是我所做的唯一更改，但是我遇到了这个错误：

Error (active)  CS1061  'RouteHandlerBuilder' does not contain a definition for 'WithOpenApi' and no accessible extension method 'WithOpenApi' accepting a first argument of type 'RouteHandlerBuilder' could be found (are you missing a using directive or an assembly reference?)

我遇到了这个文档，但它没有解决问题：https://learn.microsoft.com/en-us/aspnet/core/tutorials/getting-started-with-swashbuckle?view=aspnetcore-8.0&tabs =netcore-cli

我对 azuresql 学习页面也有同样的问题。

我遵循 .NET CLI 步骤，为了让控制台应用程序连接到我的 azure sql 数据库，我从引用的 url 添加了两个 nuget、一个 using 和几行 swagger 行：

dotnet添加包Microsoft.AspNetCore.OpenApi dotnet 添加包 Swashbuckle.AspNetCore ...

using Microsoft.AspNetCore.OpenApi;
...

builder.Services.AddEndpointsApiExplorer();
builder.Services.AddSwaggerGen();
...

if (app.Environment.IsDevelopment())
{
    app.UseSwagger();
    app.UseSwaggerUI();
}

祝你好运
