FluentMigrator.DotNet.Cli --no-connection throws exception

I am trying to generate a migration script without a live database running. The following command results in an exception.

dotnet-fm migrate -p Postgres --no-connection -a Migrations.dll -o=db.sql

@igitur Thanks for mentioning this. I opened a new ticket. In the future, consider opening a ticket as I almost lost track of this. I was on vacation for one week. If I was on vacation for two, my brain probably would’ve been too foggy to remember your comment in this email 😃 LOL

Hi

Just upgraded from v3.1.3 to v3.2.1 and I noticed that 156f5f6723e6e7ffb00909e8115b976fa7a9da3b broke something for me. I’m also generating a .sql file containing all my migrations, using .AsGlobalPreview(), but I would like each migration to be wrapped in a BEGIN TRANSACTION and COMMIT TRANSACTION in the output SQL.

After 156f5f6723e6e7ffb00909e8115b976fa7a9da3b this BeginScope(); is never called so I don’t see the transaction statements in my generated SQL anymore. To me, this is a breaking change/regression.
