The ApplicationScopedSettingAttribute class is used to specify that an application settings property has a common value for all users of an application. It cannot be inherited.

The ConfigurationManager class is used to provide access to configuration files for client applications.

There are three building blocks of .NET Framework, which are as follows:

1. Common Language Runtime (CLR)
2. Common Type System (CTS)
3. Common Language Specification(CLS)

The Process.Start method is used to start a Windows application and is registered in the system registry on a computer.

The Demand method is used to decide at runtime whether all callers in the call stack have been granted the permission specified by a current permission object by implementing class library.

An application configuration file is used to install it on a client computer along with an application and ensure that the settings in the application configuration file are applied.

The Account property is used to specify the security context of the Windows service application. In the Properties window of the Visual Studio .NET Component Designer, you can set the Account property to LocalService, LocalSystem, NetworkService, or User value.

Use the following properties to specify the individual settings for each service in a service database:

• DisplayName
• ServiceName
• ServicesDependOn
• StartType

The Publisher policy configuration file contains compatibility information issued by the publisher of a shared component. It ensures that the latest version of the shared component is used by all applications using the component.

The Global Assembly Cache (Gacutil.exe) tool is used to view and manipulate the contents of the global assembly cache. Microsoft Management Console (MMC) is a Windows utility designed to manage servers and services through a common user interface.

Publisher policy files contain compatibility information issued by the publisher of a shared component. These files ensure that the latest version of the shared component is used by all applications using the component.

The TypeLoadException exception is thrown when the common language runtime (CLR) is unable to find an assembly or the type within the assembly, or cannot load the type.

The Strong Name (Sn.exe) tool is used to sign assemblies with strong names. It also provides signature generation, signature verification, and key management.

For deploying shared assemblies, the binding policy that is a set of rules determines the place to search for the assembly and version to bind to the application. The searching process of the CLR involves the following three stages of the binding policy resolution:

1. Application policy resolution
2. Publisher policy resolution
3. Administrator policy resolution

The following are the steps that determine the correct version of an assembly:

1. The CLR examines the application configuration file.
2. It examines the publisher policy file.
3. It examines the machine configuration file.

Use components that provide services and resources and release the resources explicitly by the components using the Dispose method.

The Source property of the EventLog class is used to specify the source name to register and use when writing to the event log.

The CreateEventSource method of the EventLog class establishes an application as a valid event source for writing event information to a particular event log on a computer.

Develop an application to log important information of the application while it is executing and to write message text to the event log.

Perform an integration testing for an application and ensure that when the Write() method of the Debug class or the Trace class is called, each time only one entry is added to the event log.

The SystemException class throws an exception when an error occurs in an application using the Common Language Runtime (CLR).

The Process class can be used to print a word document with the help of the Print attribute.

The ProcessModule and ProcessModuleCollection classes can be used to get the complete information about modules used in a given application.

The Breakpoint is used to analyze variables, data records, and other settings in an application.

The Data Breakpoint is used during the execution of an application to change the value of the variables defined in the application.

The Runtime Debugger (Cordbg.exe) is a tool that provides command-line debugging services.

The Locals window is a debugging window and its contents change to reflect only the variables applicable to the current procedure. Global variables and variables in other projects are not accessible from the Locals window.

The Write method of the Debug class displays messages and writes variable values to the Output window, when an application is either stopped or paused.

The Immediate mode of the Command window is used for debugging .NET applications. This mode evaluates expressions, executes command statements, and prints values of variables defined in the application code.

The Print method of the Debug class can be used to display a message with a line terminator in the trace listeners collection.

Trace switch is an object that exists in the application code that allows filtering information. It allows enabling, disabling, and filtering of output in an application.

The Output debugging window is used to display status messages at runtime. Its content is cleared each time the application is compiled or run.

The Call Stack debugging window displays a list of currently active procedure calls during break mode.

A client-activated .NET Remoting object is created to ensure that an object logs error and warning messages to a log file and Windows application log.

The Watch window is used to see the values of variables within different scopes, i.e., module level, procedure level, and global variables.

The Assert method of the Trace class is used to check for a condition and displays a message if the condition is false.

The Cordbg.exe tool is used to debug the application from a command prompt. It provides command-line debugging services. It also helps to find and fix bugs in programs that target the .NET Framework common language runtime.

The Call Stack debugging window is used for viewing the list of currently active procedure calls.

The Log method of the Debugger class writes tracing and debugging messages that are displayed in the output window of the IDE.

Use the TraceSwitch class within a code and whenever the code uses Trace logging, it consults with the TraceSwitch level to verify whether or not to log information.

The Query property of the ManagementEventWatcher class is used to get or set the criteria to apply to events.

The Management class is used to represent a Common Information Model (CIM) management class. It is a WMI class such as Win32_LogicalDisk and Win32_Process.

Use the Unchanged member of the AuthenticationLevel enumeration to specify that the authentication level should remain the same as before.

The base keyword can be used when a subclass needs to refer to its immediate baseclass.
