    I stumbled upon an issue after following the steps described in http://documentation.telerik.com/openaccess-orm/quick-start-scenarios/getting-started-root-quickstart-vs-light-switch-wcf-ria . I can generate the Model and the Service just fine and adding the DataSource to the Lightswitch project also proceeds without a problem.

    If I afterwards create a Desktop client with a screen based on the OpenAccess Service, I can filter and view the data properly, but any attempt at editing or deleting existing records results in an error message stating "Specified entity is not managed by a context". Adding new records works alright (and the newly added records exhibit the same symptoms).

    I'm working in Visual Studio 2013 and followed the steps from the Quick Start guide. Is there something I'm missing here? Did anybody succeed at getting a LightSwitch-editable Service from OpenAccess or is it some sort of a known issue that's not stated anywhere explicitly?

    Hello Martyna,

    Based on the provided details I was able to reproduce this behavior but unfortunately I cannot give you any workarounds at the moment.

    I have addressed a new task in our documentation for specifying more details in the LightSwitch article that you have found and we already have a task for improving the LightSwitch integration but I cannot give you a time frame for its implementation.

    Please accept our apologies for the inconvenience caused.
