Using an Asynchronous Client Socket. Asynchronous operations require a callback method to return the result of the operation.
If your application does not need to know the result, then no callback method is required. The example code in this section demonstrates using a method to start connecting to a network device and a callback method to complete the connection, a method to start sending data and a callback method to complete the send, and a method to start receiving data and a callback method to end receiving data. Asynchronous sockets use multiple threads from the system thread pool to process network connections. One thread is responsible for initiating the sending or receiving of data; other threads complete the connection to the network device and send or receive the data. In the following examples, instances of the System.Threading.ManualResetEvent class are used to suspend execution of the main thread and signal when execution can continue. Am on Android.

How Do I: Create a Desktop Project for Installing Multiple CAB files on a Mobile Device? Dynamic LINQ (Part 1: Using the LINQ Dynamic Query Library) LINQ (language integrated query) is one of the new features provided with VS 2008 and .NET 3.5.
LINQ makes the concept of querying data a first class programming concept in .NET, and enables you to efficiently express queries in your programming language of choice. One of the benefits of LINQ is that it enables you to write type-safe queries in VB and C#. This means you get compile-time checking of your LINQ queries, and full intellisense and refactoring support over your code: While writing type-safe queries is great for most scenarios, there are cases where you want the flexibility to dynamically construct queries on the fly. For example: you might want to provide business intelligence UI within your application that allows an end-user business analyst to use drop-downs to build and express their own custom queries/views on top of data. Traditionally these types of dynamic query scenarios are often handled by concatenating strings together to construct dynamic SQL queries. Scott. Session Variables.

Connection Strings. A connection string contains initialization information that is passed as a parameter from a data provider to a data source.
The syntax depends on the data provider, and the connection string is parsed during the attempt to open a connection. Connection strings used by the Entity Framework contain information used to connect to the underlying ADO.NET data provider that supports the Entity Framework. They also contain information about the required model and mapping files.
Connection String Parameters The format of a connection string is a semicolon-delimited list of key/value parameter pairs: keyword1=value; keyword2=value; Model and Mapping File Locations The Metadata parameter contains a list of locations for the EntityClient provider to search for model and mapping files. Embedded resources are specified as follows: Metadata= The following options are available for defining the location of an embedded resource: Metadata= 1.0.0.0, neutral, a14f3033def15840/model.csdl|model.ssdl|model.msl.
