Thank you Steve.

This is very helpful.

I'm looking for a solution where the service can be both a NetDataContract and a DataContract simultaneously. This way, if someone creates a proxy and wants to use it as a mechanism to return a concrete object because they are not a .Net client, then it works. Maybe the ServiceKnownType is good for this. Using example 1, I can code to interfaces inside my WCF classes but always render out a concrete implementation vs. an interface.

However, some of my consumers will be .Net. In fact the .Net consumers are in-house developers that insist on passing and returning interfaces. I can have them use my application tier (which would look like example 2), or I can have them use my web tier (example 1). But my web tier does schema validation and versioning, etc. and I would prefer that everyone use the web tier.

The example you provided doesn't have DataMember or DataContract attributes. I need those so proxy generators can infer a schema and talk SOAP. But I'd like my in-house guys to be able to create a channel and use .Net serialization.

Do you think this is possible?

I think, it will be very supportive because visual studios will cover all complications. This will be comfortable for me in preparation of mcts practice exams and i will share with you after completion of course. Best of luck.

Hello,

Can you please offer an update to these opinions, now we are in July 2009 and Resharper is version 4.5

Thank you very much.

I have been running a D620

Kirk — Tue, 23 Jun 2009 16:28:09 -0400

I have been running a D620 with 1 gig RAM in standard slot and 1 gig in secondary slot in D-Dock with GeForce FX 5500 PCI card. Have been using laptop monitor + secondary LCD + third LCD with no problems for a year. I upgraded my secondary RAM to a 2 gig stick giving a total of 3 gig and now recieve error 12 code for PCI card. When I remove RAM PCI vid works as before.

As mentioned above with other Dell models they seem to work fine with up to 2 gig of RAM but not with 4. It would seem the D620 does not work with even the 3 gig.

Hi,

I have somet queries on Duplex implementation.

Scenario: I'm working on real time application for exam, student(client)should not navigate to next question without teacher request to change to question now. like navigation should manage from the server, MoveToNext Question..

How to implement Server-Client communication.

Hello Rashmi. i don't know

Anonymous — Tue, 31 Mar 2009 04:07:26 -0400

Hello Rashmi.
i don't know what exactly you are trying to do and your requirement. if you want server should comunicate before your client ping to server. you need to use run the server in dual mode. OperationContext.Current.GetCallbackChannel(), this will never work. in many cases unless client register with server, server doesn't know to whom are all it should send alarm... in reall scenario it is not needed at all./

Hah. Sorry, Abby...we seem

Steve Seymour — Mon, 16 Mar 2009 10:44:00 -0400

Hah. Sorry, Abby...we seem to be so busy these days that for the 1000 posts we'd like to put up here, we never find the time to actually do the writing. Kind of bothers me a bit, but--oh well.

You should see my setup: I have two 24" on top, and one 24" on the bottom (in the middle of the two on top). In the next couple of days I'm going to hook in another 24" on the bottom which I'll keep off to the side a bit (otherwise it would get in the way of my windows, and I'm talking the holes in the side of a house variety here :) ).

Top left monitor: email and IM windows

Top right monitor: Windows explorer and development environment "extra" windows (such as Resharper windows, of course). I also have a browser open up on this monitor.

Bottom monitor: Development environment

Why? It helps me move as fast as possible and allows me to remove annoyances that would clutter up my mind just enough to lose focus on the itty-bitty details that we deal with everyday. Instead, I get to focus on what I need to focus on and not get distracted by things such as IM windows popping up, etc.

Paul — Thu, 05 Mar 2009 04:43:37 -0500

I have a Dell XFR D630 with a ATI FirePro 2260 in the D/Dock and am having the same issue. I have been working on it for the past 2-3 days and cannot resolve it!!! It is driving me nuts. I am forced to use the ATI FirePro 2260 PCI because it is the only card that has 2x DisplayPort output. This will allow me to drive 2x 30" monitors. I have already solved the OS/drivers issue by finding the ATI WDDM 1.1 drivers (Engineering Sample). Ohh, I am trying to get it to work on Windows 7 64-bit Beta, which should be pretty similar to Vista.

When I unplug a ram stick, it works. Everything works fine, it boots it recognizes the PCI card and everything works. But when I have memory in both banks, I get BSOD errors. Even if I disable every other component.

When I set the BIOS to use the PCI video card, it will lock up and will not get out of POST. But when I set it to Internal Video card, Windows will give me a BSOD error. When I hot dock, I get the Code 12 error with insufficient resources. I feel like I have exhausted all my options and don't know what else to try. Even when I try to do a clean install, I will be BSOD just from booting from the DVD to install.

What else can I try???

You will want to do this

Rjae Easton — Thu, 12 Feb 2009 10:37:53 -0500

You will want to do this only after all instances of Visual Studio are closed, otherwise your changes will be replaced.

abby, the hacker chick blog — Mon, 09 Feb 2009 22:10:48 -0500

I just came back to see if you had any new posts up - are you trying to compete with me for longest delay between blogs? :-)

I still want to hear from you on your send all nulls to /dev/null solution - were you able to implement that?

I've been running 6 D820's

Anonymous — Fri, 06 Feb 2009 15:42:45 -0500

I've been running 6 D820's or D830's each with 3 external monitors plus the laptop monitor successfully in our CPA office for two or 3 years now. I started out with the ATI Fire MV cards in the dock, but SP3 requires the dock and laptop be the same brand now, so last summer I switched th NVidia 6200 based Jaton 338PCI-DVI cards for the docks. (I have to remove the plastic wire holder off internal vga connector where it attaches to the card for it to fit in the dock, and cut a piece off the side of the blue vga cable connector for it to fit onto the vga connector) (The laptops all have the NVidia NVS 110, 120, 130, or 140 cards built into them). I have always had to change the default Bios to use internal video card as primary to get all 4 monitors to work, otherwise only the Dock video card is enabled when plugged into the doc. I first install the dell driver with the laptop off the dock, and after that is working good, I boot it on dock with the video card installed in the dock, and when it sees the new driver, direct it to the NVidea based driver that i've previously copies somewhere onto the hard drive. The first time you set up a laptop there may be a few freezups during boot, but it get's over this. Currently I am using dells D830 driver for the internal card, dated 2/22/2008, release 6.14.11.7431, and for the dock card using Nvidias 12/5/2007 driver release 6.14.11.6921. I am using the most recent Bios releases from Dell, this is important, early bios releases don't seem to work as well.

This worked great until recently one computer got a virus. I did a windows repair install, and since then the dock video card won't work even if the internal video card is set as primary, unless I hold the laptop off the dock untill it is finished with the bios boot, and then quickly put it on the dock for the windows boot. I have removed and replaced all the drivers several times. Short of reinstalling windows, does anyone have any ideas of how to fix this?

Hi As i gone throw this

Anonymous — Tue, 16 Dec 2008 05:35:22 -0500

As i gone throw this document and found what i am really looking for, but question here for me to how to proceed for this. If you have some example kind of thing please give that.

My problem:
I want to test an API. but where i am sending these tests they don't want to have dependency like VS Studio or NUNIT. It would be just like Java's Jar file which you can run with JVM requiring no other tools. similarly if I gave some body that dll/exe whatever feel Ok, must run with .Net Framework which by default come with Windows XP.

I would be highly thankful to you.

Thanks

Hi.. I am using the WCF

Rashmi — Thu, 27 Nov 2008 04:05:46 -0500

Hi..

I am using the WCF mechanism(Duplex communication) to communicate between the Client and server.
I am sending the data to Client from server as below
IMessageServiceCallback callback= OperationContext.Current.GetCallbackChannel()
This is working fine when Client initiates the communication first. Means Client sends the message to server
and server reply to that Client using the the above code. However this is not working if the Server wants to send the data to client before Client initiates the communciation. I am getting the exception"" Null reference exception".
Could you please help me in resolving this.
I read in the few articles server can also initiate the communication. But this is not happening in my case.

Also I would like to know is it possible that multiple clients listening to server message?
Waiting for your reply.

Thanks
Rashmi.

It's coming.

All you dev heads out there

Rjae Easton — Wed, 19 Nov 2008 13:12:00 -0500

All you dev heads out there should go read Abby's blog. She gets it.

Yeah, Abby, I guess I prefer the vertical stack - and I've tested that preference for two months now by using side-by-side arrangement. (I was forced into this after a move to a temporary house where I don't want to drill mounting hardware into the wall.)

I highly recommend 27" over 24" to anyone making a new purchase. Text is considerably larger and thus much less work on the eyes. When I work from Steve's house (24" monitors) I feel the difference.

What does one do with so much real estate? Well my typical setup is the following:

Bottom monitor is always dedicated to whatever editor I am using. For the most part that is Visual Studio.
Top monitor has: browser, several IM chats, email, and my favorite Windows console. It also has my unit test runner and tail sessions.

Now what I really want is one of those spiffy tablets like you have. Steve and I are currently in the research phase for a new product, code named "The Kitchen", that is geared towards touchscreens. :^)
