Based on the online documentation from IdeaBlade DevForce, the message “There is no endpoint listening on …” indicates that the client is unable to communicate with the server.

You may these troubleshooting steps:

• For Silverlight application while debugging and testing in Visual Studio, the web project must be the startup project.
• Make sure the service is running.

For more detail information, please check it in here.

Please provide us with following information so that we can check whether the problem was caused by the project template or not.

• Operating system version, for example: Windows 7 Professional Service Pack 1 32-bit.
• Version of MS Visual Studio, for example: Visual Studio 2010 SP1.
• Intersoft WebUI Studio version, for example: Intersoft WebUI Studio 2012 R2.
• DevForce version, for example: DevForce 2010 v6.1.7.0.
• Does SqlExpress service enabled or not?
• What is the name of the project template, for example: Intersoft ClientUI MVVM Data Application (DevForce)

Look forward to hearing back from you.

Hi Yudi,

The following is my Configuration infomations:

I know that if I use project template like this: Intersoft ClientUI MVVM Data Application (DevForce),and just override the Ado.net Data entity Model as my own Data entity Model,it can work fine,but if I use project template ClientUI MVVM Application, it cause the above errors....

Hi Yudi,

I have solved the problem now,I didn't set localcopy= true,so it cause the problem, thank you  all the same, I have another problem now.When I install webui,the devforce services install automaticlly,if I want to create a project using Wcf RIA services,but it may auto load the devforce service,how to set it to avoid auto generating devforce service when creating a clientUi MVVM application project??

Glad to hear that set LocalCopy to true solve the problem.

About the other problem, I assume that you would like to disable DevForce code generation. If my assumption is correct then there are two ways to enable or disable DevForce code generation for the entity models.

• On a per-EDMX basis
  You can switch between the DevForce code generator and the Entity Framework default generator for a specific entity model by setting the DevForce Enabled field on the EDMX property sheet:
• Globally for all Visual Studio
  You can enable or disable the DevForce extension itself from within the Visual Studio Extension Manager. Disabling the extension both removes the DevForce properties from the designer and disables DevForce code generation.

Please let us know whether this helps or not.

Hi Yudi,

I got it now,I do it as you told me,it is right now, Thank you very much!
