问题
I'm trying out the new LightSwitch beta 1 and getting the following error when I try to build. Not much special - I tried to create a new screen based off of data sources from an existing database. Of course, there's no place to add references.
Error 5 The type or namespace name 'DomainServices' does not exist in the namespace 'System.ServiceModel' (are you missing an assembly reference?) [...]DataClientImplementation.cs 19 37 ClientGenerated
Anyone else playing with this new stuff?
If Microsoft is smart, they'll be monitoring StackOverflow as well and can ask followup questions of me to narrow down the issue ;-)
OK, by a suggestion by Jeff below:
Prior to the uninstall of the existing RIA:
System.ServiceModel.DomainServices.EntityFramework.dll System.ServiceModel.DomainServices.EntityFramework.xml System.ServiceModel.DomainServices.Hosting.dll System.ServiceModel.DomainServices.Hosting.OData.dll System.ServiceModel.DomainServices.Hosting.OData.xml System.ServiceModel.DomainServices.Hosting.xml System.ServiceModel.DomainServices.Server.dll System.ServiceModel.DomainServices.Server.xml
After reinstalling from the LightSwitch iso:
Microsoft.ServiceModel.DomainServices.Tools.dll Microsoft.ServiceModel.DomainServices.Tools.xml System.ServiceModel.DomainServices.EntityFramework.dll System.ServiceModel.DomainServices.EntityFramework.xml System.ServiceModel.DomainServices.Hosting.dll System.ServiceModel.DomainServices.Hosting.OData.dll System.ServiceModel.DomainServices.Hosting.OData.xml System.ServiceModel.DomainServices.Hosting.xml System.ServiceModel.DomainServices.Server.dll System.ServiceModel.DomainServices.Server.xml

It sounds like the Install failed to properly install Ria Services.
On the install disk, goto WCU\Silverlight\ and try installing riaservices manually.
The Dll's should be located:
C:\Program Files\Microsoft SDKs\RIA Services\v1.0\Libraries\Server
or
C:\Program Files (x86)\Microsoft SDKs\RIA Services\v1.0\Libraries\Server
