Scaffold-DbContext does not emit warning messages for failed entity generation

[Axioma-ShirokovPN]

If table contains columns with UDDT, it can't be exported and there is no log information why.

Steps to reproduce

Install Visual Studio 2017 RC1.
Install MSSQL Server Express 2016.
Create schema Users or remove it from code.
In DB create simple UDDT: CREATE TYPE [Users].[UserName] FROM [nvarchar](20) NOT NULL
And create simple table: CREATE TABLE [Users].[Users]( [UserId] [int] IDENTITY(1,1) NOT NULL, [UserName] [Users].[UserName] NOT NULL, CONSTRAINT [PK_Users.Users:UserId] PRIMARY KEY CLUSTERED ( [UserId] ASC )WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [UsersData] ) ON [UsersData]
Next in VS2017RC1 command line:
Scaffold-DbContext "Server=localhost\SQLEXPRESS; Database=SimpleDB; User Id=Test; Password=Test; MultipleActiveResultSets=true;" Microsoft.EntityFrameworkCore.SqlServer -OutputDir Data\Models\Users -Schema Users -Force -Verbose
After this, we will receive:

[Table("Users", Schema = "Users")]
    public partial class Users
    {
        public long UserId { get; set; }
    }

Where is column UserName?! And this for all UDDT.

Key -Verbose in command parameters, but nothing output about this. If your table contains all columns with UDDT - you will receive empty log and simple string // Unable to generate entity type for table 'Users.Users'. Please see the warning messages. in Context.cs
It mean - there is no any info\warnings\errors (it mean ok - isn't it?) in command line with -Verbose key, but receive full zero in code.

With build 15.0.0+26222.1.d15rel I no longer see the precise issue above i.e. the generated Users class has a UserName property of type string. However I've confirmed the larger issue that warning messages don't appear when (for any reason) we can't generate the EntityType - I'm continuing to track that down.

I am frustrated by the fact it simply returns "Build failed." with no further information on how to diagnose the issue that caused the failure.

@markti If you're hitting that, the compilation errors should be listed in Visual Studio's Error List tool window.

Marking for re-triage. This (not showing log messages during Scaffold-DbContext) is a good candidate for 1.1.2.
