Hi All, Am mucking around with the new SL DevForce. Cannot seem to get the "DevForce Silverlight Application" template to run in Visual Basic. Have run through the "4 Simple Steps" pdf 5 times now and am still getting a list of 106 errors (i think there are more but error count has maxed out) when I go to build. Example of the errors are:
- Error    1    Type 'DomainModel.Request' is not defined.    C:\Dev\Research\Silverlight\Request6\OPS\OPSWeb\OPSWeb.Model1.Designer.vb    83    91    OPS
- Error    3    'Name' is not declared. File I/O functionality is available in the 'Microsoft.VisualBasic' namespace.    C:\Dev\Research\Silverlight\Request6\OPS\OPSWeb\OPSWeb.Model1.Designer.vb    125    14    OPS
- Error    44    'Public Property IsCompleted() As Boolean' has multiple definitions with identical signatures.    C:\Dev\Research\Silverlight\Request6\OPS\OPSWeb\Model1.Designer.vb    458    21    OPSWeb
- Error    56    Base class 'IdeaBlade.EntityModel.v4.Entity' specified for class 'Request' cannot be different from the base class 'System.Data.Objects.DataClasses.EntityObject' of one of its other partial types.    C:\Dev\Research\Silverlight\Request6\OPS\OPSWeb\OPSWeb.Model1.Designer.vb    101    14    OPSWeb
- Error    106    Type argument 'OPS.Request' does not inherit from or implement the constraint type 'IdeaBlade.EntityModel.v4.IEntityBase'.    C:\Dev\Research\Silverlight\Request6\OPS\OPSWeb\OPSWeb.Model1.Designer.vb    666    65    OPSWeb


I have done the "4 simple steps" pdf with the c# template and have got it to work fine. But as soon as i try to do the exact same thing in VB it doesnt seem to like it at all. Im all ears to find out if there is something I'm missing here. I made sure that I downloaded the latest versions of all software.

PLEASE HELP!!

Unfortunately, you can't (easily) use the 2 project type of solution with VB, due to namespace issues.  The generated models for both the Entity Model and Domain Model are not namespace-qualified in VB, so both models are defined in the project namespace, causing collisions.
 
Take a look at the "Silverlight Next Steps" sample for a solution structure which will work in VB.  That sample isn't too far off the "4 Simple Steps" functionality, and actually represents a more realistic project structure anyway.
