modifying the RemoteBaseURL and Servicename to the formats you suggested has resolved the problem. I am now able to connect using the IdeaBlade.Core.IdeaBladeConfig.Instance approach. This gives us a lot more flexibility in how we manage our connections and in supporting OOB.

Thanks

A Silverlight application which does not have either an app.config or a ServiceReferences.ClientConfig will assume that the EntityService address is from the same host as the XAP was downloaded from. So, if the XAP was downloaded from http://dataservices.leafdev.lbmx.com/LEAFBOS/ClientBin/, then the service address default would be http://dataservices.leafdev.lbmx/LEAFBOS/EntityService.svc/sl. So if this is correct you don't need to manually specify the service information to SL at all.

If you do find you need or want to pass the info in the appSettings, the RemoteBaseURL and service name here are actually incorrect. We don't document this very clearly, but the RemoteBaseUrl should just be the host name, in this case "http://dataservices.lbmx.com", and the service name should be "LEAFBOS/EntityService.svc/sl".

defining the serviceModel settings on both Client and Server were a result of making changes to both sides in an attempt to resolve this problem as I was not sure what was happening. I have made the changes to the IIS application name and I

can connect but only using the Servicereferences.ClientConfig on the client side

http://schemas.ideablade.com/2010/IdeaBladeConfig">

I am now using client side code in the Silverlight app and passing in the EntityService information via initParams. I am also setting values in IsolatedStorage as I need to support OOB mode. Here is that web.config

    http://dataservices.leafdev.lbmx.com/LEAFBOS"/>

this approach does not work using the IdeaBlade.Core.IdeaBladeConfig.Instance and setting the values from the web.config. I have found that I need to use the Servicereferences.ClientConfig on the Silverlight client. I would like to be able to set my IdeaBlade server configuration in code. Any suggestions?

We call a WCF helper method named ServiceHostingEnvironment.EnsureServiceAvailable to start up the EntityServer service. It looks like this call doesn't recognize a URI with the %20 as a valid URI and is therefore throwing.

I'm afraid there's no way of working around this right now. In the next release we'll add a fix to translate the %20 back to a space, but until then the only thing you can do is change your IIS application name.

P.S. I'm curious why you're defining the serviceModel settings on both client and server - do you need to override the defaults, or has our documentation led you to believe this was necessary?

I am getting the following error when I attempt to start my BOS server. I have included my configuration information for both client and server. The EntityService starts up but not the server. Not sure where to where to look for a solution to this.

Caught exception: IdeaBlade.EntityModel.EntityServerException: Unable to start EntityServer.svc service: The virtual path '/LEAF%20BOS/EntityServer.svc/sl' points outside of the virtual application '/LEAF BOS'. Parameter name: virtualPath ---> System.ArgumentException: The virtual path '/LEAF%20BOS/EntityServer.svc/sl' points outside of the virtual application '/LEAF BOS'. Parameter name: virtualPath at System.ServiceModel.ServiceHostingEnvironment.NormalizeVirtualPath(String virtualPath) at System.ServiceModel.ServiceHostingEnvironment.EnsureServiceAvailable(String virtualPath) at IdeaBlade.EntityModel.Server.RemoteEntityService.GetHostedEntityServer(String pServiceName) --- End of inner exception stack trace --- at IdeaBlade.EntityModel.Server.RemoteEntityService.GetHostedEntityServer(String pServiceName) at IdeaBlade.EntityModel.Server.RemoteEntityService.GetEntityServerName(String dataSourceExtension, String compositionContextName) at SyncInvokeGetEntityServerName(Object , Object[] , Object[] ) at System.ServiceModel.Dispatcher.SyncMethodInvoker.Invoke(Object instance, Object[] inputs, Object[]& outputs) at System.ServiceModel.Dispatcher.DispatchOperationRuntime.InvokeBegin(MessageRpc& rpc) at System.ServiceModel.Dispatcher.ImmutableDispatchRuntime.ProcessMessage5(MessageRpc& rpc) at System.ServiceModel.Dispatcher.ImmutableDispatchRuntime.ProcessMessage31(MessageRpc& rpc) at System.ServiceModel.Dispatcher.MessageRpc.Process(Boolean isOperationContextSet)

this is my ServiceReferences.ClientConfig section from my Silverlight Application

                      address="http://dataservices.leafdev.lbmx.com/LEAF BOS/EntityService.svc/sl"
                binding="customBinding" bindingConfiguration="customBinaryBinding"
                contract="IdeaBlade.EntityModel.IEntityServiceContractAsync"
                />

                      address="http://dataservices.leafdev.lbmx.com/LEAF BOS/EntityServer.svc/sl"
                binding="customBinding" bindingConfiguration="customBinaryBinding"
                contract="IdeaBlade.EntityModel.IEntityServerContractAsync"
                />

and here is my web config for my BOS server
