In my previous posts I had metioned on how to get SSL working with the new HttpListener class in whidbey 2.0 Beta1. It was sort of difficult to use the command line httpcfg tool as I had to manually open the machine store, pick a cert and copy its thumbprint...

I just checked and saw that I had 15 invitations to MSN messenger 8.0 beta. If anyone needs an invite leave your email. Update: They are all gone. I will post another one when I have more invites. Mahesh

I have talked a lot about WCF's extensibility model and I never knew how much of the core functionality can be extended until a recent deep dive session with one of our customers developing on WCF. The client had a multi tier application with the middle...

One of the most common problems we debug with WCF proxies invoked from WinForm/XAML app's is a perceived hang when duplex contract's are involved. The app usually has a " click to invoke proxy " button that invokes a method (which will callback the client...

Ever wondered how to programatically configure SMTP service on IIS to route mails to a particular domain? IIS settings are maintained in a Metabase file. We can programatically edit this metafile to add settings that will route emails to any domain (say...

After I posted my earlier entry on debugging WCF apps, I thought it would be a good idea to explain the different WCF runtime blocks . This way users can see how each block/class fits in the bigger picture and how the runtime processes new channels/messages...

With .NET 1.1, a hosting api was shipped under System.Web.Hosting namespace that let users execute ASPX pages without needing to have IIS. The namespace has got some cool features with whidbey beta 1. Whidbey beta 1 also introduced another cool class...

One common question I see on Remoting forum is how to configure a proxy to use a particular channel from the set of registered channels for communicating when creating a proxy. For instance consider an Remoting application that exposes both a secure and...

Why should this be a post topic? From the naming, its clear that one is for extending the "Service" and the other is for extending "Endpoints". We recently had a interesting question posted in our internal forums on this topic and so though I should share...

The June CTP of WinFx introduces some breaking changes and the detailed API changes can be downloaded from here . One of the changes we made is to the InstanceContextMode enum. This enum denotes how WCF manages the InstanceContext lifetime. InstanceContext...

Users have frequently wanted the ability to remotely synchronize relational nodes in a peer to peer fashion using SyncServices for ADO.NET. We have a sample demonstrating remote synchronization by using Windows Communication Foundation (WCF). I wanted...

In .Net 2.0 (Whidbey), Remoting introduced support for IPC channels. This was a quick way for local machine processes to communicate with objects hosted locally. Now there is a small behavior that users might not be aware of when they are unmarshalling...

There has been some cases where users have reported an AccessViolation when upgrading their Remoting app's to Whidbey. Some users found that the problem reprod only when they had some anti virus software (Nod32 in particular) installed and the AV went...

Wanted to write up a post on whats the difference between "auto" opening a WCF Channel and explicitly calling "Open" on it. Michael Maruchek posted a detailed and well explained post at http://blogs.msdn.com/mjm/archive/2006/11/13/auto-open-part-1.aspx...

When I am debugging any WCF runtime bug, I classify it in two categories. One that needs IDE (simple logic bugs) and others that need WinDbg. Every one is familiar with the IDE debugging and will leave that topic for another day. Today I wanted to talk...

I got more time to play with the desktop search are was about to post my views on it. There has been ton of blogging going on and more information related reviews and user experience can be found at msnsearch blog , scoble blog #1 and scoble blog # 2...

[ Note : Source for this sample can be downloaded from http://www.maheshwar.net/projects/Sync/DbSyncProviderSample.zip . Just ensure that you modify the connectionstrings in properties\settings file to point to the correct database. This sample is based...

InstanceContext has two methods, ReleaseServiceInstance and GetServiceInstance , that can be used by users to dynamically release and create new service instances. Service instance is the actual .Net instance of the contract on which operations are invoked...

Technorati Tags: Silverlight , POX , XmlSerializer , JSON Scott Guthrie laid out all the details regarding Silverlight 2.0 Beta1 this morning and if you haven't had a chance to see the keynote then you can view it from VisitMix site. Scott briefly mentioned...

With the WCF Feb CTP release the IChannelBehavior interface has been removed. In previous CTP's this interface would be used to write a behavior that will let users add customization points on the client side. Actually, we have rewired the behavior mechanism...

Mix 2008 is just hours away and I am very excited to talk about all the work we have been doing to get the beta of Silverlight 2 ready. Scott Guthrie already kicked off the information flow with 2 wonderful posts on Silverlight 2 and Blend . We have worked...

With the feb CTP release we added the ability for multiple ServiceEndpoint's on a service to share a common listen URI. I wanted to walk through a sample explaining how to achieve this. Lets assume we have this sample Service. [ServiceContract]...

Peter torr posted his experiences * Installing* (notice the bold on installing) firefox and got swamped with backlash comments from FF patrons. He then followed it up with a follow up post and I think both the posts are excellent. Gr8 posts Peter and...

Microsoft recently announced Silverlight at the Mix 07 conference. Now that its released I can freely talk about what I am working on. I am really excited to start working on the connected systems API's for Silverlight 1.1. If you refer to the Silverlight...

Sometime last Friday, admist cheers and high fives, our lead PM resolved the last bug that stopped us from signing off on WCF(code named Indigo). Bug # 1 was opened way back when Indigo was in planning stages and with this bug we signed off on the product...
