Here are my notes, laid out as a Q&A, for the next exam I am preparing, the last one to become Microsoft Certified Professional Developer (MCPD): ASP.NET Developer 3.5 ...wow ;-)
I have prepared this article using OneNote within SkyDrive. This is by the way an excellent tool to take notes, share them and access them from everywhere and for free.
Q1: What are the different Page directives?
The author of this article gives this definition for Pages Directives:
Asp.Net Page directives are something that is a part of every asp.net pages. Page directives are instructions, inserted at the top of an ASP.NET page, to control the behavior of the asp.net pages. So it is type of mixed settings related to how a page should render and processed.
The reference article on MSDN gives all the details regarding Page Directives.
Q2: What are the different application folders?
Based on this MSDN article, ASP.NET recognizes certain folder names that you can use for specific types of content. The table below lists the reserved folder names and the type of files that the folders typically contain. Following folders can be used:
· App_Browsers: Contains browser definitions (.browser files)
· App_Code: Contains source code for utility classes and business objects that you want to compile as part of your application.
· App_Data: Contains application data files including MDF files, XML files, as well as other data store files.
· App_GlobalResources: Contains resources (.resx and .resources files) that are compiled into assemblies with global scope
· App_LocalResources: Contains resources that are associated with a specific page, user control, or master page in an application
· App_Themes: Contains a collection of files (.skin and .css files...) that define the appearance of ASP.NET Web pages and controls
· App_WebReferences: Contains files that defines a Web reference for use in an application.(.wsdl , .xsd,.disco and .discomap files)
· Bin: Contains compiled assemblies (.dll files)
Q3: What is a JSON web service in asp.net?
JSON for JavaScript Object Notation specifies how the Web method return-type is serialized. For your information, the other one is XML.
Using this article and the code given by the author, i made a web service test and play with the result. Here is the result I get while invoking the web service:
<?xml version="1.0" encoding="utf-8" ?>
<string xmlns="http://tempuri.org/">
[["CarNumber1","CarColor1","CarMotor1"],["CarNumber2","CarColor2","CarMotor2"]]
</string>
I am not really sure of the added value of such format… will see...
Q4: What is the difference between a web site and a web application?
Here is what I found when googling this question:
A web site is just a group of all files in a folder and sub folders. There is no project file. All files under the specific folder - including your word documents, text files, images etc. are part of the web site.
You have to deploy all files including source files (unless you pre compile them) to the server. Files are compiled dynamically during run time.
As a conclusion, the author writes:
· A web site is good for you if you just want to create web sites and share with others. It is ideal for new projects.
· However, "web application project" is better if you are planning to migrate your Visual Studio 2003 or 2002 web sites into Visual Studio 2005. Otherwise you may end up spending lot of time to exclude unwanted files from your web site folder.

Q5: What are Session state modes and how to use them?
Session state modes define the way how session state information is stored. Here are the definitions taken from the MSDN article and the main information to remember:
· InProc mode, which stores session state in memory on the Web server. This is the default.
· StateServer mode, which stores session state in a separate process called the ASP.NET state service. This ensures that session state is preserved if the Web application is restarted and also makes session state available to multiple Web servers in a Web farm.
· SQLServer mode stores session state in a SQL Server database. This ensures that session state is preserved if the Web application is restarted and also makes session state available to multiple Web servers in a Web farm.
· Custom mode, which enables you to specify a custom storage provider.
· Off mode, which disables session state.
Q6: What are "Custom Profile Provider" and "Custom Membership Provider"?
For this subject, i also googled and find the following sites that contain definitions and samples:
· For Profile provider (DavidHayden.com)
· For Membership Provider (MSDN)
Bonus "question", list of control we should know for this exam, with a link to an MSDN article
· FormView:
The FormView control is used to display a single record from a data source in a table. When using the FormView control, you specify templates to display and edit bound values. The templates contain formatting, controls, and binding expressions to create the form. The FormView control is often used in combination with a GridView control for master/detail scenarios. This section contains the following topics about the FormView control
· ListView:
Displays the values of a data source by using user-defined templates. The ListView control enables users to select, sort, delete, edit, and insert records.
· DataList:
A data bound list control that displays items using templates.
· Repeater:
A data-bound list control that allows custom layout by repeating a specified template for each item displayed in the list.
· DetailsView:
Displays the values of a single record from a data source in a table, where each data row represents a field of the record. The DetailsView control allows you to edit, delete, and insert records.
