Mention the two major categories that distinctly classify the variables of C# programs.

Correct Answer: You can deploy an ASPNET Web application using either the Windows Installer deployment or ClickOnce deployment technique

Correct Answer: => Windows Installer => ClickOnce => XCOPY => Copy Web Site => Publish Web Site tool

Correct Answer: Workflows serve the purpose of automating business processes Now, since each type of business has a wide range of problems; therefore, a workflow platform needs to be extensible WF provides you with a set of base activities, such as IfElse, Code, and Delay, to build a workflow You can extend these activities or build new activities to meet your requirements Besides activities, you can also extend services, such as tracking, management, and persistence, provided by the runtime engine

Correct Answer: In WF 40, the following two types of workflows are used: Flowchart workflows - Helps you to create workflows using the common flowchart elements In WF, the Flowchart activity is generally used to implement a non-sequential workflow, and occasionally it implements sequential workflows in case the FlowDecision nodes are not used The Flowchart activity contains a collection of flow nodes, which inherit from the FlowNode class The following types of nodes or elements can be a part of a flowchart: => FlowStep - Executes activities of a flowchart in a sequence => FlowDecision - Shows the execution on the basis of a Boolean condition It is similar to the If construct => FlowSwitch - Shows the execution on the basis of an exclusive switch It is similar to the Switch construct Procedural workflows - Helps you to create workflows using basic and sequential execution standards In WF, procedural workflows use flow control constructs, such as While, Switch, ForEach, and If, to execute activities These flow control constructs are similar to those found in procedural languages Procedural workflows can also contain other flow control activities, such as Flowchart and Sequence

Correct Answer: Windows Workflow Foundation (WF) is a technology that was first introduced in NET Framework 30 WF consists of a programming model, a workflow runtime engine, workflow designer, a rules engine, and tools to quickly build workflow-based applications on Windows WF facilitates the separation between the business process code and the actual implementation code

Correct Answer: LINQ is a programming model that is the composition of general-purpose standard query operators that allow you to work with data, regardless of the data source in any NET based programming language It is the name given to a set of technologies based on the integration of query capabilities into any NET language

Correct Answer: In Visual Basic, the basic syntax of a LINQ query starts with the From clause and ends with the Select or Group By clause In addition, you can use the Where, Order By, and Order By Descending clauses to perform additional functions, such as filtering data and generating the data in a specific order In C#, the basic syntax of a LINQ query starts with the From clause and ends with the Select or group by clause In addition, you can use the where, orderby, and Orderby descending clauses to perform additional functions, such as filtering data and generating the data in a specific order

Correct Answer: After you add a LINQ to SQL Classes item to a project and open the O/R Designer, the empty design surface represents an empty DataContext class ready to be configured The DataContext class is a LINQ to SQL class that acts as a conduit between a SQL Server database and the LINQ to SQL entity classes mapped to that database This class contains the connection string information and the methods for connecting to a database and manipulating the data in the database It is configured with connection information provided by the first item that is dragged onto the design surface

Correct Answer: The standard query operators in LINQ are the extension methods that form the LINQ pattern These operators form an API that enables querying of any NET array or collection It operates on sequences and allows you to perform operations, such as determining if a value exists in the sequence and performing an aggregated function, such as a summation over a sequence

Correct Answer: The standard query operators implement the IEnumerable or the IQueryable interface in C# and the IEnumerable(Of T) or the IQueryable(Of T) interface in Visual Basic
