Building an empty MVC Framework 1. Create an empty template

2. Create folders Controllers, Models, Views3. Create HomeController.cs under the Controllers folder

Select the Controllers folder, right-add-new item, select the MVC controller class, add HomeController.cs.

usingSystem;usingSystem.Collections.Generic;usingSystem.Linq;usingSystem.Threading.Tasks;usingMicrosoft.AspNetCore.Http;usingMICROSOFT.ASPNETCORE.MVC;namespacerazormvc.controllers{ Public classHomecontroller:controller {//Get:home         PublicActionResult Index () {returnView (); }    }}

4. Create HomeModel.cs under the Models folder

using System; using System.Collections.Generic; using System.Linq; using System.Threading.Tasks; namespace razormvc.models{    publicclass  homemodel    {    }}

5. Add _layout.cshtml in the Views folder

<!DOCTYPE HTML><HTMLLang= "en"><Head>    <MetaCharSet= "UTF-8">    <Metaname= "Viewport"content= "Width=device-width, initial-scale=1.0">    <Metahttp-equiv= "X-ua-compatible"content= "Ie=edge">    <title>@ViewData ["Title"]</title></Head><Body>@RenderBody () @RenderSection ("Scripts", false)</Body></HTML>

6. Add _viewstart.cshtml in the Views folder

@{    "~/views/_layout.cshtml";}

7. Add _viewimports.cshtml in the Views folder

*, Microsoft.AspNetCore.Mvc.TagHelpers

8. Adjust Startup.cs

 Public voidconfigureservices (iservicecollection services) {services. Addmvc ();//Registration Services} Public voidConfigure (Iapplicationbuilder app, Ihostingenvironment env) {if(env. Isdevelopment ()) {app.    Usedeveloperexceptionpage (); }    Else{app. Useexceptionhandler ("/home/error"); App.    Usehsts (); } app.    Usehttpsredirection (); App.    Usestaticfiles (); App.    Usecookiepolicy (); App.    Usesession (); App. USEMVC (Routes={routes. MapRoute (Name:"default", Template:"{controller=home}/{action=index}/{id?}"); });}

9. The adjustment can be saved as a template (you can skip, wait for it to be finished together) EF Core build 1. Install EF Core

Tools > NuGet Package Manager > Package Manager console
RunInstall-Package Microsoft.EntityFrameworkCore.SqlServer
RunInstall-Package Microsoft.EntityFrameworkCore.Tools
RunInstall-Package Microsoft.VisualStudio.Web.CodeGeneration.Design
Listen up, all of you.

2. Create a model from an existing database

Scaffold-dbcontext"server=.;D Atabase=test;uid=test;pwd=test; " Microsoft.entityframeworkcore.sqlserver-outputdirmodels

You can -Tables specify which tables you want to generate entities for by adding parameters to the preceding command. For example -Tables Blog,Post .

3. Deleting an inline context configuration

Open itModels\BloggingContext.cs
Delete OnConfiguring(...) method

4. Registering and configuring the context in Startup.cs

 Public void configureservices (iservicecollection services) {    services. Addmvc ();     var @" server=.;D Atabase=test;uid=test;pwd=test; " ;    Services. Adddbcontext<testContext> (Options and options). Usesqlserver (connection));}

5. System Generation test Page

In Solution Explorer, right-click the Controllers folder, and then select Add, Controller ...
Select View uses the Entity Framework's MVC controller, and then click OK
Set model class to "Test" and "Data context class" to "TestContext"
Click "Add"
Run up to test database connections

Using Redis storage session

Modify the configuration file according to your needs, here directly https://www.cnblogs.com/shouwu/p/6180652.html,

1. Add a NuGet Package

Microsoft.AspNetCore.Session; Microsoft.AspNetCore.DataProtection.Redis; Microsoft.Extensions.Caching.Redis.Core; Microsoft.AspNetCore.Http;      // extended method when using session

2. Add Redis configuration in Appsettings.json

{  "Logging": {    "LogLevel": {      "Default":"Warning"    }  },  "allowedhosts":"*",  "Webconfig": {    "Redis": {      "Connection":"ip:6379,allowadmin=true,password=test",      "InstanceName":"name"    },    "Sessiontimeout":" -"  }}

3. In the Startup.cs class, add the code as shown in the following example

 Public Get ; }  Public Startup (iconfiguration configuration) {    = configuration;}

Configureservices () Increase

#regionSave session with RedisvarRedisconn = configuration["WebConfig:Redis:Connection"];varRedisinstancename = configuration["WebConfig:Redis:InstanceName"];//long minutes after the Session expiresvarSessionouttime = configuration.getvalue<int> ("Webconfig:sessiontimeout", -);varRedis =StackExchange.Redis.ConnectionMultiplexer.Connect (redisconn); services. Adddataprotection (). Persistkeystoredis (Redis,"Dataprotection-test-keys"); services. Adddistributedrediscache (Option={    //Redis Connection StringOption. Configuration =Redisconn; //Redis Instance NameOption. INSTANCENAME =redisinstancename;});#endregion//add session and set expiration durationServices. Addsession (options = options. IdleTimeout = Timespan.fromminutes (sessionouttime); });

Configure () in the app. Usemvc before increase

App. Usesession ();

Redis Storage Session

HttpContext.Session.SetString ("UserName", UserName); HttpContext.Session.GetString ("UserName");

General Storage Redis

 Public Get Set ; }  Public Mytoolcontroller (Idistributedcache rcache) {    = Rcache;} _rcache.setstring ("UserName", UserName); _rcache.getstring ("  UserName");
