wcf endpoint issue

Hi, based on recommendations on this forum, I made a wcf application to serve my 2 applications that need data.
So my solution looks like this now:
Data Access Layer project
wcf service library project
viewmodel project that extracts data from the wcf service library
a wpf application that binds to viewmodels from the viewmodel project
a test app that tests the wcf service & models
a web app that provides input for some of the models
The unit tests I made to test the wcf works perfectly as long as the service is up and running.
The wpf application fails to run as soon as I try to use the wcf service though. Always same thing: can't find the endpoint.
So when I use the models in the test app, everything works fine, when I use the same models in my wpf app, they throw exceptions as soon as they contact the wcf service. Same problem when my webapplication does this.
Can someone help me out please?

Certainly: try the WCF forum[^]

Posted this when I had worked for 15 hours straight and was tired so didn't check whether there was a wcf forum to begin with. I've reposted it in the correct forum. Could you please check out the post there. Would really appreciate an answer.

Not unless you explain exactly what exceptions you are seeing, and where they occur.

Exception happens as soon as I create the client(call the constructor).
The exception is in dutch but I'll do my best to translate:
Kan het eindpuntelement met naam lezingen en contract LezingenService.ILezingenService niet vinden in het configuratiegedeelte van de ServiceModel-client. Dit wordt mogelijk veroorzaakt doordat geen configuratiebestand is gevonden voor de toepassing, of doordat geen einpuntelement dat overeenkomt met deze naam kan worden gevonden in het client-element.
Translated to english this means:
Can't find the endpoint with the name lezingen and contract LezingenService.ILezingenService in the configuration section of the ServiceModel client. This could be caused by a missing configuration file for the application or because no endpoint was found in the client element with this name.
I'll provide you with the app.config files:
Below service app.config:

InstanceContext context = new InstanceContext(this);
LezingenServiceClient client = new LezingenServiceClient(context, "lezingen");

Why have you posted this here? This is nothing to do with C#, it's a WCF issue.

You can't write drivers in a managed language.

Howto -> learn C.

First, you can't use C# to do this.

Well, you could, but you'd be practically rewriting the Windows Driver SDK in C# to do it.

Next, writing drivers is not for newbies. It involves writing code in C and learning how to do debugging in the Windows NT Kernel. You're NOT going to find a couple of pages that shows you the basics of how to do this. It's a very advanced black art and requires you know how Windows works internally.

Then you need to start at http://msdn.microsoft.com/en-gb/windows/hardware/hh852365.aspx[^]. But be aware that writing drivers is an advanced topic, and from the tone of your question, you are not at an advanced level yet.

Code Review?

Hey guys,

I have been working on modifying some code and a few other things in my project as I have been learning of better techniques. I have been able to reduce my code by a few thousand lines, by writing some Functions to do what I need, rather than copying code everywhere. What I would like to do is post my code in a public ::workspace and share it with the community so that you all can see it and maybe help me make it even better. If I did that, would there be anyone willing to help, and if so, what is the best method of me uploading it? I can use git with a new ::workspace, and there really is not much to it at the moment. It is simply one form, with about 14-15 buttons, a DataGridView and a few ComboBoxes.

The Functions I have written, I have to wonder if they can't be combined somehow for even less code, but I haven't had the time to look into it.

Basically, this form, when completed, will access several different MySQL Tables (Yes, I know I could combine them, and eventually I will, but right now, we want them this way for learning purposes.). The ComboBoxes then fill with data based on the Table selected by the buttons. I will be adding buttons to copy information into a different table, as well as a few other things.

Anyways, that's what I was wondering. Thoughts?

TL;DR.

Post it, and FxCop will seem to be friendly and easy-going.
