Tools: Add -WhatIf parameter to Update-Database

[bricelam]

This would show the migrations that would be applied to the database.

This functionality is also related to #577.

Maybe --dry-run ? (see here)

[bricelam]

-WhatIf is a first-class concept in PowerShell. We could consider using --dry-run in the DNX (and Console) commands, but I think there is more value in using a common language between the different interfaces.

[glen-84]

Ah, okay, I didn't know about that. It's a bit of an odd name. :smile:

I think the DNX commands use lower or possibly camelCase, so I guess it'll be --whatif, --what-if, or --whatIf.

[matt-goldman]

+1 this would be so useful. Also agree with using the -WhatIf (even if in lowercase) as its familiar from PowerShell.

[stap123]

bicep also uses what-if as the syntax for this

Hello, any updates?

[bricelam]

No updates. Today you can use Get-Migration to see which migrations are pending and Script-Migration to see the SQL they'll generate.
