Question

I have some Fluent NHibernate code that runs fine on my local visual studio, but once it gets deployed to a test server I have the following error – one I’ve never come across before:

Unable to cast object of type
‘NHibernate.Impl.DelayedEnumerator1[Core.FileLoad.File]' to type
'Remotion.Linq.QueryableBase1[Core.FileLoad.File]’.

The code that causes this error is:

var files = _readRepository
.Query<File>()
.Where(f => f.Id == fileId)
.ToFuture();

_readRepository
.Query<Record>()
.Where(f => f.File.Id == fileId)
.ToFuture();

var file = files.ToList().First();

Answer 1

Ooops – the code I copied was not the actual code. There was a (Querybase) cast at the start also.
Once I removed that everything worked fine.

Thanks
