MSResultSetGenerator does not work any more

I try to generate a typed result set. I first added a new data source to my project and then changed the custom tool property of the .xsd file from MSDataSetGenerator to MSResultSetGenerator. This was working a few days ago, but recently, it stopped working. I now get the following error when I right click on my .xsd and then "run custom tool":

Error 102 Custom tool error: Failed to generate code. Illegal characters in path. C:\Users\Mathias\Documents\Visual Studio 2005\Projects\WindowsApplication9\WindowsApplication9\NorthwindDataSet1.xsd 1 1 WindowsApplication9

I tried this in several projects, for example I created a new WinForms project and then just added the norhwind.sdf sample database.

I use Visual Studio 2005 + SP1 + SP1 Vista patch (beta) + SQL Compact Edition + ADO .NET Sync Services CTP on Vista Ultimate.

Things I tried to repair this so far:
- VS2005 repair setup
- Reinstalled SQL Compact Edition
- Reinstalled ADO .NET Sync Services
- Reinstalled VS2005 SP1

I have the same problem and it seems that when I try to generate the data source with an empty sql mobile database it works.

When I add tables to the database it does not.

This suggest to me that it must have something to do with the naming conventions of the database tables and/or fields. I'm trying that next.

Did you make any progress Please report
