Sqllite is not supported: https://github.com/schambers/fluentmigrator/issues/94

If I delete Migration.Runner from demo project /bin directory, web site works ok If I copy files from better CMS project's /lib directory, everything seems to be ok.

Maybe nuget must copy migration.runner.dll to project's Lib directory and reference it from that directory ant not from packages?

I encountered the same issue the past couple of days.

[Audrunas]

Which version are you using and what's the exception?

[mwpowellhtx]

When I say, 'the same' there's nothing mysterious about that: BadImageFormatException.

The parent project is set to run Any CPU / prefer 32-bit, so I believe things are being coerced to 32-bit since FM assemblies are all 32-bit.

AFAIK, this is based on 'latest' code checked out, or at least branched from, a recent FM version.

More precisely,

[assembly: AssemblyVersion("1.2.1.0")]
[assembly: AssemblyFileVersion("1.2.1.0")]

[mwpowellhtx]

Which 'resolving' that, manifests in a conflict with another dependency I've assumed.

Instead of mucking with decoupling SQLite or anything else that might be pulling it down to the 32-bit realm, I decided to roll my own migrations.

Try to add "FluentMigrator.Tools" from NuGet (this is separate package, not so popular and appears at "Page 2" in search results for "FluentMigrator" keyword). This package has AnyCPU build, countrary to FluentMigrator package apparently bundled with x86-only binary for tools subfolder)
