VS 2008 Beta 2 WCF SVCUtil error

Svcutil.exe is used to generate the WCF proxies. In VS 2008 Beta 2, if you create simple WCF application and try to generate proxy of your service, you may encounter the error that states

"
Unhandled Exception: System.IO.FileLoadException: Could not load file or assembl
y 'svcutil, Version=3.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a' o
r one of its dependencies. Strong name validation failed. (Exception from HRESUL
T: 0x8013141A)
File name: 'svcutil, Version=3.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11
d50a3a' ---> System.Security.SecurityException: Strong name validation failed. (
Exception from HRESULT: 0x8013141A)
The Zone of the assembly that failed was:
MyComputer
"
Solution

The problem is that SVCutil.exe is not been verified as a strong Name and one needs to do this in order to rectify the issues
1. Open Command Prompt
2. Go to C:\Program Files\Microsoft SDKs\Windows\V6.0A\Bin folder
This is the folder where by default, all the utilities provided by .NET 3.5 is placed.
3. run sn -Vr svcutil.exe

it will respond as verification entry has been added for the assembly svcutil.

This is a generic problem and might can occur to other utilities. All you need to do is to put your utility name in place of svcutil.exe in the above and You are Done !!! I am sure this will be resolve in the next beta of VS 2008

Visual Studio 2008 targets Multiple Frameworks

Way back in Year 2005, i had blogged on why Visual Studio 2005 doesn't target .NET 1.x(if you missed it to read, click here). The problem is overcomed by Visual Studio 2008 aka ORCAS. Expected to be released in feb , 2008, Orcas is having an ample set of features to talk about apart from LINQ , which is one of the most awaited feature. So we have new things line up in areas of WF, WCF and many more and i would be blogging more on these areas as and when time permits. One of the most exciting feature that i came about is multi-targetting feature of Visual Studio 2008. what it means is that by Default, Visual Studio 2008 target .NET framework 3.5 but you can also get an opportunity to create projects targeting .NET 1.x, 2.0 and .NET 3.0 as well which was never been supported by any Visual Studio IDE. well now below are the ways by which you can change the target framework for the specific projects in Visual Studio 2008

1. when you create a Visual studio 2008 project, the option is available on the top right corner to select the version

2. You can also go on Project Properties --- > Application tab --- > set the target framework

Isn't this awsome feature.

Port Sharing Features in WCF

HTTP with Port 80 allows to share Port 80 with multiple web applications. If you want other TCP ports to be shared by multiple applications, there is not an easy way to achieve the same. Windows Communication Foundation (WCF) allows multiple application to share the same TCP port. I had written an article on the same as how WCF enable a TCP port to be shared by multiple applications

Please have a look on Port sharing feature of WCF

Now comes MSCD

Recently Microsoft havce recently launched its new product called Microsoft Secure Content Downloader (MSCD)which is based on Bittorrent and is used to download the Microsoft content securely. one of the limitation of the MCSD is that it cannot cross firewalls so presently , though it is in testing phase, this might be for only end users who are not behind firewalls. Also MCSD downloads limited Microsoft products like Visual Studio 2008, soon we might be able to see it for large downloads if this is been a success :) .. cool, so now if you are like me and wants to play with the new MCSD, Click Here to download the New MCSD

No More OEM Microsoft Office 2003 after June 30th

After June 30, 2007, OEM Microsoft Office 2003 will no longer be available from Microsoft. I do feel that this is really a nice decision on behalf of Microsoft. It has been some time that developers and end users have started working on Office 2k7 , they have given various comments but have appreciated the Office 2k7. This decision will not only give a decent path to say Good Bye to Ok but also invite a lot of professionals to use Office 2k7 who are still sticked with Office 2k3. More information about the same is available by clicking Here

TechMela 2007 , Agenda

Moving ahead with my blog entries on TechMela 2007, below is the Agenda for the same on Day 14,15 and 16th Respectively. Click on the below image to get more clearer view

No TechEd 2007 this time in India, TechMela Aka TechED 2007

On 28th April, I have blogged a post about TechEd 2007 dates in which i mention about the techEd, happening in Mumbai from June 13. To know more about that posts, click Here .To get more curious, one of the bad news is that this time, there will be no Tech Ed 2007 across cities in India. The TechEd has been wrapped with a new name called TechMela and this TechMela is happening in only one location in India i.e. Mumbai. It seems Microsoft have done it to make the TechMela a huge success and to bring the Indian IT mass in one location. This TechMela is divided into 2 zones.

1. for Business Users, its on 13th June
2. for Technology users, its on 14,15and 16th June

Not sure, if its going to be a good success. For the people, who are living in other locations apart from mumbai, there is something good. Well not good as TechEd alias TechMela, Just keep an eye on my blog. I am going to blog it soon !!!
