Columnstore index build error #719

• SqlPackage or DacFx Version: I don't know, how to find out? I only use dotnet build.
• .NET Framework (Windows-only) or .NET Core: .NET Core 10.0.100-rc.1.25451.107 (from dotnet --version)
• Environment (local platform and source/target platforms): Microsoft.Build.Sql 2.0.0

Steps to Reproduce:

1. Create new SQL Project: dotnet new sqlproj -n ProductsTutorial
2. Add table with columnstore index:

CREATE TABLE [dbo].[Product](
    [ProductID] [int] IDENTITY(1,1) NOT NULL,
    [ProductName] [nvarchar](200) NOT NULL,
    index ix clustered columnstore
);

3. Build with: dotnet build
4. Observe the error: product.sql(4,5,4,5): Build error SQL46010: Incorrect syntax near 'index'.

Did this occur in prior versions? If not - which version(s) did it work in? I don't know
