我絕對是新的ASP.NET核心。我正在按照官方文檔構建一個ASP.NET Core web api試用項目。我想成立PostgreSQL的這個項目,所以我沒有以下內容:設置ASP.NET核心與PostgresSQL錯誤
我的模型:
using Microsoft.EntityFrameworkCore;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Threading.Tasks;
namespace Api_trial.Models
{
public class Student
{
public int Id { get; set; }
public string Name { get; set; }
public int Grade { get; set; }
}
public class WebAPIDataContext : DbContext
{
public WebAPIDataContext(DbContextOptions<WebAPIDataContext> options)
: base(options)
{
}
public DbSet<Student> Students { get; set; }
}
}
appsettings.json:
{
"ConnectionStrings": {
"DataAccessPostgreSqlProvider": "User ID=postgres;Password=root;Host=localhost;Port=5432;Database=asp_trial_api;Pooling=true;"
},
"Logging": {
"IncludeScopes": false,
"LogLevel": {
"Default": "Debug",
"System": "Information",
"Microsoft": "Information"
}
}
}
startup.cs:
public void ConfigureServices(IServiceCollection services)
{
// Add framework services.
services.AddApplicationInsightsTelemetry(Configuration);
services.AddDbContext<WebAPIDataContext>(options => {
options.UseNpgsql(Configuration.GetConnectionString("DataAccessPostgreSqlProvider"));
});
services.AddMvc();
services.AddSwaggerGen();
}
和我的project.json:
{
"dependencies": {
"Microsoft.NETCore.App": {
"version": "1.0.1",
"type": "platform"
},
"Microsoft.ApplicationInsights.AspNetCore": "1.0.0",
"Microsoft.AspNetCore.Mvc": "1.0.1",

]
}
},
"buildOptions": {
"emitEntryPoint": true,
"preserveCompilationContext": true
},
"runtimeOptions": {
"configProperties": {
"System.GC.Server": true
}
},
"publishOptions": {
"include": [
"wwwroot",
"**/*.cshtml",
"appsettings.json",
"web.config"
]
},
"scripts": {
"postpublish": [ "dotnet publish-iis --publish-folder %publish:OutputPath% --framework %publish:FullTargetFramework%" ]
}
}
不過,我得到我的startup.cs以下錯誤:
我恢復軟件包,但我基本都不知道它的真正含義,什麼必須是完成。我還沒有執行:dotnet ef migration
也許你應該遷移到核心1.1? – Alexan
在這種情況下,我需要將所有內容升級到1.1,對吧? – Nitish
