Update-Database will output SQL that has incorrect newlines

[Mike Peterson]

If a migration uses \n or \r instead of \r\n for a newline, the SQL after the \n will be output to the command window

Steps to reproduce

Create a migration that does some SQL. This can be an INSERT, UPDATE, or SELECT statement

For example

public partial class NewLineDemo : DbMigration
{
    public override void Up()
    {
        // this gets outputted to console
        Sql( "BEGIN\nSELECT [Id] FROM [Person]\nEND" );

        // this gets outputted to console
        Sql( "BEGIN\nSELECT [Id], [FirstName] FROM [Person]\nEND" );

        // this does not get outputted to console
        Sql( $"BEGIN{Environment.NewLine}SELECT [Id], [FirstName], [LastName] FROM [Person]{Environment.NewLine}END" );

        // this does not get outputted to console
        Sql( @"
BEGIN
    SELECT [Id], [FirstName], [LastName], [BirthDate] FROM [Person]
END" );

        // this get outputted to console
        Sql( "BEGIN\nSELECT [Id], [FirstName], [LastName], [Email] FROM [Person]\nEND" );
    }
        
    public override void Down()
    {
           
    }
}

now do Update-Database and you'll see the SQL that uses just \n output to the package manager console

This issue has been closed because EF6 is no longer being actively developed. We are instead focusing on stability of the codebase, which means we will only make changes to address security issues. See the repo README for more information.
