Update your connectionStrings

Configure a connection string for SQL Server in the Web.config

  <connectionStrings>
    <add name="DefaultConnection" connectionString="Data 
    Source=YOURTDATABASE; 
    Initial Catalog=YOURNAMEDB; Persist Security     
    Info=True;User ID=YOURUSER;Password=YOURPASSWORD”"
    providerName="System.Data.SqlClient" />

Configure validation logic for passwords

By default, if you don't customise anything, Identity configures a default set of validation rules for new passwords. If you want to change these values, you can change the file called App_Start/IdentityConfig.cs

    manager.PasswordValidator = new PasswordValidator
    {
        RequiredLength = 6, // Passwords must be at least 6 characters
        RequireNonLetterOrDigit = false, // Passwords must have at least one digit ('0'-'9')
        RequireDigit = false, // Passwords must have at least one non alphanumeric character
        RequireLowercase = false, // // Passwords must have at least one lowercase ('a'-'z')
        RequireUppercase = false, // Passwords must have at least one uppercase ('A'-'Z')
    };

PasswordValidator Class

Set the color in the project

In our PCL, the file App.xaml you can change the color

    <Color x:Key="MainColor">#273646</Color>
    <Color x:Key="FontColor">#2d8dd6</Color>
    <Color x:Key="AccentColor1">#2371aa</Color>
    <Color x:Key="AccentColor2">#e44235</Color>
    <Color x:Key="BackgroundColor">#e9eeef</Color>

Resource Dictionaries

Set your API

In our PCL, the file Services/HttpService.cs you must put the url of your api and prefix

   private const string UrlApi = "YOURAPI";
   private const string tokenType = "bearer";
   protected const string FirstVersion = "/api";

Security

OAuth 2.0 protocol and Microsoft Owin Library will help us. Owin is basically creating own pipeline between iis and application to manage requests.

In the file Startup.Auth.cs an OWIN Authorization server is configured to accept login (token) HTTP requests at /Token endpoint and external login requests at /api/Account/ExternalLogin

• OAuthAuthorizationServerOptions Class
• Oauth
• OAuthAuthorizationServerOptions Token

Requirements

• Visual Studio 2017 version 15.3 or Visual Studio for Mac version 7.3
• Windows 10
• Microsoft Azure subscription

Tools used

The following tools are essential:

• Genymotion - The Best Android Emulator

• Quicktype - Generate c# classes from json.
• Color Adobe - To create color schemes for my designs. For this project I have choosen
