Answer 1

You can do something like this:
using (var context = new PrincipalContext(ContextType.Domain))
{
var principal = UserPrincipal.FindByIdentity(context, User.Identity.Name);
var firstName = principal.GivenName;
var lastName = principal.Surname;
}
You'll need to add a reference to the System.DirectoryServices.AccountManagement assembly.
You can add a Razor helper like so:
#helper AccountName()
{
using (var context = new PrincipalContext(ContextType.Domain))
{
var principal = UserPrincipal.FindByIdentity(context, User.Identity.Name);
#principal.GivenName #principal.Surname
}
}
If you indend on doing this from the view, rather than the controller, you need to add an assembly reference to your web.config as well:
<add assembly="System.DirectoryServices.AccountManagement" />
Add that under configuration/system.web/assemblies.

Another option, without requiring a helper... You could just declare context and principal before you need to utilize these values, and then utilize it like a standard output...
#{ // anywhere before needed in cshtml file or view
var context = new PrincipalContext(ContextType.Domain);
var principal = UserPrincipal.FindByIdentity(context, User.Identity.Name);
}
Then anywhere within the document, just call each variable as needed:
#principal.GivenName // first name
#principal.Surname // last name

If you have many controllers then using #vcsjones approach might be painfull.
Therefore I'd suggest creating extension method for TIdentity.
public static string GetFullName(this IIdentity id)
{
if (id == null) return null;
using (var context = new PrincipalContext(ContextType.Domain))
{
var userPrincipal = UserPrincipal.FindByIdentity(context, id.Name);
return userPrincipal != null ? $"{userPrincipal.GivenName} {userPrincipal.Surname}" : null;
}
}
And then you can use it in your view:
<p>Hello, #User.Identity.GetFullName()!</p>

If you've upgraded to Identity 2 and are using claims, then this kind of info would be a claim. Try creating an extension method:
public static string GetFullName(this IIdentity id)
{
var claimsIdentity = id as ClaimsIdentity;
return claimsIdentity == null
? id.Name
: string.Format("{0} {1}",
claimsIdentity.FindFirst(ClaimTypes.GivenName).Value,
claimsIdentity.FindFirst(ClaimTypes.Surname).Value);
}
Then you can use it in the view like this:
#Html.ActionLink("Hello " + User.Identity.GetFullName() + "!", "Manage", "Account", routeValues: null, htmlAttributes: new { title = "Manage" })

Add the below in your _ViewImports.cshtml page :
#using System.DirectoryServices.AccountManagement
Then, in your _Layouts.cshtml place the below :
#{
var context = new PrincipalContext(ContextType.Domain);
var principal = UserPrincipal.FindByIdentity(context, User.Identity.Name);}
Note: You can concatenate by creating additional variable ex:
var userName = #principal.Givenname + ", " + #principal.Surname;
You can not call the variable 'userName' directly, however, you can call 'userName' anywhere on the page by creating a hidden field.
