[Dan Brown]

Hi There

I'm very new to Silverlight, i've installed silverlight 3 & the Telerik silverligh 3 controls 0n visual studio 2008.  I have tried to run the Astoria / northwind back end Demo which i downloaded from Telerik.  My problem is that i get 27 build errors.  I've tried reinstalling the Rad silverlight tools and have added them to the VS tool box, but nothing i do seams to correct  the problem

can anyone help please

Thanks a lot

Dan

Hello Dan Brown,

 

It seems that you are missing Ria Services. Our demos require Ria Services to be present on the host machine. We are working on early notification system for our setup program for such dependencies and we will try to introduce those improvements with our next release. 

There is a catch though - the latest Ria Services, now called WCF Ria Services, introduced breaking changes and our Q3 examples cannot be compiled with the latest Ria. The first option is to download a previous version of the Ria Services or  upgrade to Q3 2008 SP1 which is compatible with WCF Ria Services. 

Hope this helps.

Sincerely yours,
Milan

Hi Milan

Thanks a lot for your advice, i'm very new to silverlight so please forgive my ignorance, i just need to make sure i fully undestand what you have said.

My primery concern at the moment is to the Astoria Demo / ADO.NET DataService Demo which i downloaded from
http://www.telerik.com/account/free-trials/single-trial.aspx?pid=571


Will installing the upgrade to Q3 2008 SP1 fix my RIA  proplem with the Astoria Demo  or do i need to locat the previous RIA  Services?

which option is best in order to get the astoria Demo Working Properly?

Thanks

Dan

Hi Dan Brown,

 

Do not worry about being new to Silverlight - I will try to give you as much details as possible.

For the time being some of our Silverlight examples rely on WCF Ria Services - as a result the WCF Ria Servies should be installed on the host machine. Our latest examples are only compatible with the latest Ria Services beta release which can be downloaded from here. 

My advice is to download both the latest Ria Services and our latest service pack release (2009 Q3 SP1). Then, install Ria and after that our SP1 release. Once you have the right version of Ria you should be able to compile our samples without any problems.

Do not hesitate to write if you have more questions.

Best wishes,
Milan

Hi Milan

Thanks again for your help,

I am assuming there must be somthing wrong with my pc configuration as i get build errors on every telerik trial app, regardless of if its open acces, ajax or silverlight. i think that i probobly have to many versions of differnt service pack and ria services etc installed on my pc so i'm going to get rid of everthing this weekend and reinstall from scratch.  hopfully this will solve my problem.

I'll let you know hoe i get on

Thanks again

Dan

Hi Milan

I done a compleate reinstall of Vista and then reinstalled VS  and all the relevent silverlight tools , ria servises, SDK's etc but sadly i still have a problem  with the silverlight ASTORIA Demo

The issue is that the project does not recognise :  private global::System.Data.Services.Client.DataServiceCollection<Product>
The type or namespace name 'DataServiceCollection' does not exist in the namespace 'System.Data.Services.Client' (are you missing an assembly reference?)

this only ocours in DATA / SErvices.cs. 

As i now have the lates version of RIA services, do i need to change the Microsoft.Data.Services.Client Referance to be somthing else or change the private global::System.Data.Services.Client.DataServiceCollection<Product> to be somthing else? 

Can you advise what code i should change and where to get this project to work properly?

I have added the error and Data/Services.cs code below. 

I really hope you can help

Thanks again for everything

Dan

Hi Milan

I done a compleate reinstall of Vista and then reinstalled VS  and all the relevent silverlight tools , ria servises, SDK's etc but sadly i still have a problem  with the silverlight ASTORIA Demo

The issue is that the project does not recognise :  private global::System.Data.Services.Client.DataServiceCollection<Product>
The type or namespace name 'DataServiceCollection' does not exist in the namespace 'System.Data.Services.Client' (are you missing an assembly reference?)

this only ocours in DATA / SErvices.cs. 

As i now have the lates version of RIA services, do i need to change the Microsoft.Data.Services.Client Referance to be somthing else or change the private global::System.Data.Services.Client.DataServiceCollection<Product> to be somthing else? 

Can you advise what code i should change and where to get this project to work properly?

I have added the error and Data/Services.cs code below. 

I really hope you can help

Thanks again for everything

Dan
