[Bug] Line Characters in Generated Comments

[ExusAltimus]

Describe the bug
If there is a new line character in the extended properties of a column / table, the default .hbs / CSharpEntityTypeGenerator doesn't account for this and leaves the generated models with syntax errors due to the new line not being commented out.

Expected behavior
Split the string into lines and loop through each commenting the line out

To Reproduce
Have an extended property with a newline character

This is a battle hardened implementation:

dotnet/efcore#22937

@ErikEJ If XML comments are enabled in EF Core 5.0, then I having them in my tool seems redundant. How does one enable generation of comments using the dotnet-ef CLI? They don't seem to be enabled by default.

[ErikEJ]

@tonysneed XML comments are generated in EF Core 5! https://github.com/dotnet/efcore/blob/release/5.0/src/EFCore.Design/Scaffolding/Internal/CSharpEntityTypeGenerator.cs#L261 - they are generated by default in EF Core 6! https://github.com/dotnet/efcore/blob/main/src/EFCore.Design/Scaffolding/Internal/CSharpEntityTypeGenerator.cs#L264

[tonysneed]

How do you enable comments in EF Core 5? How do you disable them in EF Core 6? Is there a CLI parameter?

[ErikEJ]

Magic!

No, I override the linked class and use that overridden class with my EF Core 5 scaffolding tool.

There is no option to turn it off.
