metadata file '.dll' could not found in Visual Studio 2005

When I try to run the ASP.NET 2.0 web application using Visual Studio 2005 i was struck up with some irritating error message "metadata file '.dll' could not found "
Later when I explored on this I found some solutions that solved the problem in my development environment. I would like to share it here, so that it may help others.

Cause of the problem:
Files in the format: App_Web_urfile.dll are created when you compile your web application project using Visual Studio 2005. Every time you compile your solution, the Application is compiled into a 'temp' directory which gets read by IIS or the internal web server available in Visual Studio 2005. In some scenerio, especially if you do a more of testing/debugging, the temp folder gets overload and become unable to understand by the application.

The first option is
1. Clear the temp cache files.
2. Stop or Restart IIS and close your Visual Studio 2005
3. Go to: C:\WINDOWS\Microsoft.NET\Framework\v2.0.__\Temporary ASP.NET Files
4. Delete all the files
5. Re-compile your application and then test.

Hope this help

WCF REST Starter Kit Preview 2‏

The WCF REST Starter Kit is a set of features, Visual Studio templates, samples and guidance that enable users to create REST style services using WCF. While the October release of the WCF REST Starter Kit focused on building server-side REST services, the Preview 2 release adds features to make client-side REST development easier. Chief among the new functionality included in Preview 2 is a new class that provides a staged pipeline model for requesting resources over the web. Using this new HTTP client class allows the developer to plug into the various stages of communication to handle custom authentication, caching, and fault handling outside of the client’s application logic.

How "VSTO 3.0 for Office 2007 Programming" book born, a true stroy!

VSTO 3.0 for Office 2007 Programming [Buy Now]

I started my career in Microsoft technologies. I was very much keen on exploring technologies and designing applications. When I joined one of the world’s largest software services and consulting company in 2006, I was asked to explore on Microsoft’s upcoming technology SharePoint. I was just started the training material and practicing the same. And suddenly the client work has been allotted for a few which includes me in that team. After the work has been allotted for each individual in the team, I and my colleague (and a best friend) got to work on VSTO programming for InfoPath 2003 which is part of our client project. But my best friend she was not interested in VSTO work and she feels this is not the right technology for her career and raised a question for me, do you feel comfortable in VSTO? Is it good for your career growth? I said for me technology is secondary, for me I was keen on the quality of the work I do, whatever the technology may be. Few words to mention about my friend as a developer, she was an awesome developer, and any company in this world should be the luckiest company to have her as a resource.

And this is where the spark fired an idea for me to write a book on VSTO, to write book on VSTO and show everyone that technology doesn’t decide your growth it’s just your attitude plays the key role in your life. Writing a book which is fully authored by me is my long-time dream. I was thinking about this from my school days, one day in my life I will write a book. Now I got an idea for my dream, what I need is to start working on that. There is zero support and encouragement in my organization I worked, feel like stuck between office politics. Under performing guys are ruling the project to failure, even the failure doesn't reflect their originality instead they gets appreciation. So I decided to carry on my career in different organization where I can produce my excellence too. So I decided to leave the most liked and loved company in my life.

First I started writing for the publication with more energy and enthusiastic. My first delivery of chapter was on InfoPath. The chapter returned with huge amount of comments and feedback, which actually said to me better stop writing :). But my editor Jonathan Hassell and Tony Campbell was the greatest; who make me thinks get going... Later before a month of release of the book the press came up with one of the best worst news I have heard in my life, eight months of dedication, hard work and how many sleepless nights is washed away from that news. They said we have decided to withdraw from your book agreement. A few days I was upset and I bounce back with a new idea.

Added new ideas and enhanced the content and approached the Europe’s leading technical publisher PackT Publication and get a green signal precede the project. Again started the works get going and finally the book was on store for sale! Thanks to all crew members of PackT Publishing for their dedication and commitment toward the launch of this book.

When I send message to people and friends I got a great appreciation and response from different people. Those messages are refreshing and boosted my confidence to write another book immediately.

Writing a book is a great adventure ... Congratulation for your book ...... very nice cover :) - Ludovic LefortCongratulations! An awesome accomplishment that requires a great deal of focus and sacrifice to execute on. Great job! - Amanda Murphy

Get the Host name and IP address from ASP.NET

To get the Host name and IP address from your ASP.NET application, we have option is .NET. Using the using System.Net; namespace you have access to the classes which can expose the Host name and IP address.

The sample code to explain the solution. Paste the same code in the page load event of the ASP.NET page.

using System.Net;
//Get the Host name
string strHostName = string.Empty;
strHostName = Dns.GetHostName();
// Then using host name, get the IP address list..
IPHostEntry ipEntry = Dns.GetHostByName(strHostName);
//Get the IP address
IPAddress [] addr = ipEntry.AddressList;
for (int i = 0; i < addr.Length; i++)
{
Response.Write("IP Address {0}: {1} " + i + addr[i].ToString() + ", HostName: " + strHostName);
}

Composite Application Guidance for WPF and Silverlight v2.0 (PRISM)

The Composite Client Application Guidance is designed to help you more easily build modular Windows Presentation Foundation (WPF) and Silverlight client line of business applications.

These types of applications typically feature multiple screens, rich, flexible user interaction and data visualization, and role-determined behavior. They are built to last and built for change. This means that the application's expected lifetime is measured in years and that it will change in response to new, unforeseen requirements. This application may start small and over time evolve into a composite client—composite applications use loosely coupled, independently evolvable pieces that work together in the overall application.

Creating Custom Field Types in SharePoint using Visual Studio

Here we are planning to create a Custom field will auto populate with the logged in user information. First we need create project with SharePoint assembly as reference. For this create empty SharePoint Application project.
> Start Visual Studio.
> On the File menu, click New, and then click Project.
> In the Project Types pane of the New Project dialog box, select Visual C#, and then select the SharePoint category.
>In the Templates pane, click Empty. Specify a Name and Location for the project, and then click OK. Visual Studio creates a solution that contains an empty project.

Visual Studio Extensions for Windows SharePoint Services 3.0 provides support
for creating SharePoint field types through the Field Control project item.

Now we need to add a Field Control to the Project we have created.

> In the Visual Studio Solution Explorer, right-click the empty project created in the previous procedure, click Add, and then click New Item.
> In the Categories pane of the Add New Item dialog box, expand the Visual C# Project Items node, and then select the SharePoint category.
> In the Templates pane, click Field Control. Specify LoginInfoID for the Name of the field control, and then click Add. Visual Studio adds the new field control to the project.

Visual Studio adds two Microsoft Visual C# code files to the project: LoginInfoID.FieldControl.cs and LoginInfoID.Field.cs. The LogoField.Field.cs file contains code that defines a class that by default is derived from the SPFieldText class and that overrides the FieldRenderingControl property.

Now write the custom logic inside the LoginInfoID.FieldControl.cs file. Refer the this full source attached in this blog for understand the remaining. Download Source Code

Now the field control xml file and deployment.

The XML file must be named in the format fldtypes*.xml (for example, fldtypes_customfield.xml) and placed in Local_Drive:\\Program Files\Common Files\Microsoft Shared\web server extensions\12\TEMPLATE\XML
Upload all the .dll files into the Drive:\WINDOWS\assembly folder
At a command prompt, type iisreset to reset Internet Information Services (IIS).
In a view of the list to which you want to add the custom field type, click Settings, and then click Create Column.

Result as shown screenshot

CAML.NET IntelliSense for SharePoint

Excellent outcome by some of the Microsoft Technology community influencers.
CAML.NET IntelliSense for SharePoint
To build a SharePoint feature, you must write CAML, but the raw CAML schemas produce only minimal editing support in Visual Studio. This project extends the raw CAML schemas with fully annotated XSDs that enable IntelliSense to display full SDK documentation while editing SharePoint XML files. Most SharePoint developers know how to add the SharePoint schemas to Visual Studio so you get IntelliSense when editing CAML files. This is a good first step, but only provides the bare minimum of information needed to build solutions. The result is that you spend a good deal of time searching through the SDK documentation for the necessary details for using a particular CAML element or attribute, or to see the list of valid attribute values.

Error

"It is an error to use a section registered as allowDefinition='MachineToApplication' beyond application level. This error can be caused by a virtual directory not being configured as an application in IIS."

This is the error message caused when I developed the ASP.NET application my development server. After few analysis I found that web.config should be moved to root directory from the sub directory. If you all want to have a web.config in the sub-directory, then the only settings you can specify are authorization, appsettings etc., Another root cause for the problem may be you may have one duplicate web.config file in a subfolder.

Configuration Wizard An exception of type System.UnauthorizedAccessException was thrown.

Configuration Wizard An exception of type System.UnauthorizedAccessException was thrown. Additional exception information: Access is denied. (Exception from HRESULT: 0x80070005 (E_ACCESSDENIED))

Facing this problem while running the Configuration wizard after installing the MOSS 2007. Do anyone have fine solution to over come this problem?

One of the solution is : The technique to reset passwords is exactly the same as resetting the accounts used. It gives you an understanding of what accounts affect each service.Also, in some cases resetting the password for domain accounts triggers Sharepoint to reset permissions which can fix odd issues like this.

Even this doesn't solve in another environment!
