    <p>I am writing an application ( WPF ) where i use the prism framework. I have a client with the shellview. I have some module's. So that are different projects. Each module is a sepperate project. The modules are loaded by Unity.</p> <p>I have the following </p> <pre><code>Solution Client Modules Client ( app ) Common Entities Server Data Web </code></pre> <p>So you can see i have an Data Project under the server folder. There you can find the edmx. The Web project is empty, the Entities project is also empty.</p> <p>The Client (app) has a shellview with its bootstrapper. The client works. Only the data access layer must be integrated.</p> <p>What is the best solution to do the data access? WCF, something else? What template do we need to use for the entities. How can we use the service in the modules where al the code (View/ViewModel) is?</p> <p>Pff, i am looking and read so much. Found some topics on stackoverflow. But none of the topics start's from the begin. Hope someone can help me.</p>

    1. COWhich method of data access you use is pretty much orthogonal to your choice to use prism/unity. The method you choose will depend more upon other factors like what your database looks like, whether you're in control of the data store, what your scalability needs are, whether you want to use an ORM, etc.

    2. COYou should try focusing your question better. You asked a handful of questions (What method of data access? Can I use my DAL directly from my viewModel? etc.) These are all questions that you should probably ask separately and explain each thoroughly if you expect people to understand the context of your problem and offer good advice. Otherwise, it seems that you are merely saying "I designed part of this project, but got stuck... can somebody out there in internet-land do the rest for me?"

    3. COMy database is build up with the Entity Framework. Generated the code from the edmx that i builded. Scalability -> It wil only be used in my local network. I used already WCF services but not with edmx features/modules prism. Always directly from the Service to a client, with contracts that i wrote by myself. Now it should use the edmx entities. I don't want that somebody do the rest. I hope only someone can help me, to start right.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
