Exception while processing Server Explorer drag

Hi,

for the production and the development environment I use two separate MS SQL server instances.

Dragging tables from the production server instance into the LS modeling tool works fine, but dragging tables from a local SQLEXPRESS database instance an exception will be raised (see below).

Both DB instances differ mainly in the connection string that's being used

Data Source=.\SQLEXPRESS;AttachDbFilename="F:\Microsoft SQL Server\Database.mdf";Integrated Security=True;Connect Timeout=30;User Instance=True

Data Source=server.intern;Initial Catalog=Database;Integrated Security=True;Encrypt=True;Network Library=dbmssocn

How can I fix this problem?

Thx

For now, you will need to attach the database to the SQL Server instance, so that you can reference it using the Initial Catalog key instead of AttachDbFilename.

I have committed a fix for this, and beginning with the 25 July nightly build, you should be able to use MDF files directly using the AttachDbFilename key.
