At this point, let’s skip the in-depth discussion on how to deploy the . In this book, we cover the latest (at the time of this writing) release of the .

NET Framework to the machines where your application code is to run ultimately, be it a client computer, a web server, or even the cloud. NET Framework, version 4.5, which goes hand in hand with the Visual Studio 2012 release.

NET objects with VS 2005 and SQL Server 2000 or 2005. VS 2005 materializes Table Adapters, Data Sets, Binding Sources, and Binding Navigators as named objects in the form design tray.

Figure 1-5 compares the objects required by updatable ADODB Recordsets and ADO. Table Adapters and Data Sets also appear in the Toolbox's Project Name Components section; the Data section has Data Set, Binding Source, and Binding Navigator controls.

AXML files are not currently supported in Xamarin Live Player. Forms Android projects must use "Toolbar.axml" and "Tabbar.axml" for the names of the relevant layout files.

The default template uses these names; renaming them will cause rendering issues.

On most versions of windows you must first save these files to your local machine, and then unblock the file in order to read it.

Different sources require different protocols; for example, older sources may employ ODBC protocol while newer use Ole Db protocol. It also leads to bloated code impacting readability, portability, and maintenance. NET was designed for use with C# or Visual Basic, and the LINQ database querying language.

LINQ fully integrates with C# and VB code offering native code database operations, and simplifying operations even outside of database manipulation. NET for operating on various data sources, but this occurs in a more productive and less cluttered way than standard ADO. A best practice would be to utilize C#-LINQ or VB-LINQ when possible rather than employing ADO.

One tool we pay a fair amount of attention to is Visual Studio 2012, but we cover other useful tools, too.

To get our hands dirty, we write a simple C# application and highlight some of the important language elements, go through the process of building it using various tools, and look at how we can debug code.
