Async Task <object>

    public async Task<UserInfo> GetUserDataAsync(string NetworkID)
    {
        PrincipalContext principalcontext = new PrincipalContext(ContextType.Domain, ADDomain, ADUser, ADPass);
        UserPrincipal founduser = null;

        await Task.Run(() =>
        {
            founduser = UserPrincipal.FindByIdentity(principalcontext, IdentityType.SamAccountName, NetworkID);
        });

        //task.Wait();

        return founduser != null && founduser.Enabled == true ?
            new UserInfo
            {
                DisplayName = founduser.DisplayName,
                Email = founduser.EmailAddress,
                NetworkID = founduser.SamAccountName
            } : new UserInfo();
    }

This is a function that allows you to validate the user through the declaration, I can run the function with Task task = Task.Factory.StartNew (() => {}); and task.Wait (); but this will still work in sync. Executing the code above with async and waiting leaves the browser dead-locked, spinning forever and never returning a value.

This is what I am doing with my synchronous call.

Task task = Task.Factory.StartNew(() =>
            {
                founduser = UserPrincipal.FindByIdentity(principalcontext,IdentityType.SamAccountName, NetworkID);
            });

            task.Wait();

If you want to do this asynchronously, why not just return the task directly?

public Task<UserInfo> GetUserDataAsync(string NetworkID)
{
    return Task.Run(() =>
    {
        PrincipalContext principalcontext = new PrincipalContext(ContextType.Domain, ADDomain, ADUser, ADPass);
        UserPrincipal = UserPrincipal.FindByIdentity(principalcontext, IdentityType.SamAccountName, NetworkID);


        return founduser != null && founduser.Enabled == true ?
          new UserInfo
          {
            DisplayName = founduser.DisplayName,
            Email = founduser.EmailAddress,
            NetworkID = founduser.SamAccountName
          } : new UserInfo();
    });
}
