Working With ASP.Net Identity in Empty Project in Visual Studio 2013

</connectionStrings>

Step 10: Make your Web Form as a Start Page and debug the application.

Working with LocalDB

As you saw, the user registered successfully. Create more users. Use the following procedure to verify that the users are registered by the Entity Framework in the Local Database.

Step 1: Open the Server Explorer from View.

Step 2: Now you can show your table in the DefaultConnection as shown below:

Configure the OWIN Authentication

So far we have added support to register the new user. We now add support of user login to the application. The ASP.NET Identity uses OWIN Authentication as a default for forms authentication. The OWIN Cookie Authentication is a cookie and claims based authentication packages can be used by any framework that is hosted on OWIN or IIS.

Install the OWIN Authentication

Step 1: In Solution Explorer, right-click on the project to open the Manage NuGet Package and enter identity.owin in the search box and press Enter to install.

Step 2: Enter the following statement and install the package:

Microsoft.Owin.Host.SystemWeb

Adding OWIN Startup Class

Step 3: Add the OWIN Startup class to your project from "Add new item" in Solution Explorer.

Step 4: Replace the code with the following code.

Add the follow assemblies to your class:

using Microsoft.Owin.Security.Cookies;

using Microsoft.AspNet.Identity;

Now modify the code:

public void Configuration(IAppBuilder MyApp)

{

MyApp.UseCookieAuthentication(new CookieAuthenticationOptions

{

AuthenticationType = DefaultAuthenticationTypes.ApplicationCookie,

LoginPath = new PathString("/Login")

});

}

Step 5: Open the Registration.cs page and modify the code with the following code.

Add the following assembly in your class:

using Microsoft.Owin.Security;

Add the highlighted code in the method as shown below:

void Register_User()

{

var User_Store = new UserStore<IdentityUser>();

var User_Manager = new UserManager<IdentityUser>(User_Store);

var New_User = new IdentityUser() { UserName = TxtUserName.Text };

IdentityResult User_Result = User_Manager.Create(New_User, TxtUserPassword.Text);

if (User_Result.Succeeded)

{

var Auth_Manager = HttpContext.Current.GetOwinContext().Authentication;

var User_Identity = User_Manager.CreateIdentity(New_User, DefaultAuthenticationTypes.ApplicationCookie);

Auth_Manager.SignIn(new AuthenticationProperties() { }, User_Identity);

Response.Redirect("~/Login.aspx");

}

else

{

LblMessage.Text = User_Result.Errors.FirstOrDefault();

}

}

Step 6: Add a Web Form to your project named Login and add the code as shown below:

<form id="form1" runat="server">

<div>

<h3>Log In</h3>

<hr />

<asp:PlaceHolder runat="server" ID="LoginFormHolder" Visible="false">

<div style="margin-bottom: 10px">

<asp:Label runat="server" ID="LblUserName">User Name:</asp:Label>

<div>

<asp:TextBox runat="server" ID="TxtUserName" />

</div>

</div>

<div style="margin-bottom: 10px">

<asp:Label runat="server" ID="LblUserPassword">Password</asp:Label>

<div>

<asp:TextBox runat="server" ID="TxtUserPassword" TextMode="Password" />

</div>

</div>

<div style="margin-bottom: 10px">

<div>

<asp:Button runat="server" OnClick="SignIn_Click" Text="Log in" />

</div>

</div>

</asp:PlaceHolder>

<asp:PlaceHolder runat="server" ID="LogoutButtonHolder" Visible="false">

<div>

<div>

<asp:Button runat="server" OnClick="SignOut_Click" Text="Log out" />

</div>

</div>

</asp:PlaceHolder>

<asp:PlaceHolder runat="server" ID="LoginStatusHolder" Visible="false">

<p>

<asp:Literal runat="server" ID="LtlStatus" />

</p>

</asp:PlaceHolder>

</div>

</form>

Step 7: Open the Login.aspx.cs file and modify the code with the following code.

Add the following assemblies:

using Microsoft.AspNet.Identity;

using Microsoft.AspNet.Identity.EntityFramework;

using Microsoft.Owin.Security;

Code:

protected void Page_Load(object sender, EventArgs e)

{

if (!IsPostBack)

{

if (User.Identity.IsAuthenticated)

{

LtlStatus.Text = string.Format("Hello {0}!!", User.Identity.GetUserName());

LoginStatusHolder.Visible = true;

LogoutButtonHolder.Visible = true;

}

else

{

LoginFormHolder.Visible = true;

}

}

}

protected void SignIn_Click(object sender, EventArgs e)

{

var User_Store = new UserStore<IdentityUser>();

var User_Manager = new UserManager<IdentityUser>(User_Store);

var User = User_Manager.Find(TxtUserName.Text, TxtUserPassword.Text);

if (User != null)

{

var Auth_Manager = HttpContext.Current.GetOwinContext().Authentication;

var User_Identity = User_Manager.CreateIdentity(User, DefaultAuthenticationTypes.ApplicationCookie);

Auth_Manager.SignIn(new AuthenticationProperties() { IsPersistent = false }, User_Identity);

Response.Redirect("~/Login.aspx");

}

else

{

LtlStatus.Text = "Invalid username or password.";

LoginStatusHolder.Visible = true;

}

}

protected void SignOut_Click(object sender, EventArgs e)

{

var Auth_Manager = HttpContext.Current.GetOwinContext().Authentication;

Auth_Manager.SignOut();

Response.Redirect("~/Login.aspx");

}

Step 8: Ctrl+F5 to run the application.

Step 9: After logout, if you enter the invalid credentials then the following error message will displayed:

Summary

With this article you have learned how ASP.NET Identity in the Empty Project Template works. You can also apply the OWIN Cookie Authentication to your application to apply the Forms Authentication in your project. Thanks for reading. Happy Coding.
