Net升级问题

1.Net5.0升级Met6.0配置

1.1 Porgram.cs文件修改

Porgram.cs的代码更换为以下代码，会出现缺少引用的错误。var builder = WebApplication.CreateBuilder(args);无需按照提示在该文件中添加suing.下一步解决问题。

var builder = WebApplication.CreateBuilder(args);

// Add services to the container.

builder.Services.AddControllers();
// Learn more about configuring Swagger/OpenAPI at https://aka.ms/aspnetcore/swashbuckle
builder.Services.AddEndpointsApiExplorer();
builder.Services.AddSwaggerGen();

var app = builder.Build();

// Configure the HTTP request pipeline.
if (app.Environment.IsDevelopment())
{
    app.UseSwagger();
    app.UseSwaggerUI();
}

app.UseHttpsRedirection();

app.UseAuthorization();

app.MapControllers();

app.Run();

1.2 项目文件修改

右键项目->编辑项目文件然后添加<ImplicitUsings>enable</ImplicitUsings>

<PropertyGroup>
<TargetFramework>net6.0</TargetFramework>
<ImplicitUsings>enable</ImplicitUsings>
</PropertyGroup>　　

此时上次缺少引用的错误就解决了。

1.3 删除Setup.cs

Net6.0只需要一个Porgram.cs，在Net5.0项目中删除Setup.cs。
