eXtremeSQL C# Runtime Libraries
This article is only applicable to .NET Framework 4.x. eXtremeDB for .NET 5 and later is documented in the eXtremeSQL C# API for .NET Core articles.
The core eXtremeDB and eXtremeSQL runtime functionality is encapsulated in the extremedb4net.dll library which is loaded dynamically at application startup. Then the following Database.Mode values can be set to dynamically load the associated library when a Database object is instantiated, however, note that no additional library is necessary for SQL support:
|
DebugSupport
|
Load the debug library to provide additional diagnostic exceptions - highly recommended during development. When all the code is bug-free and the application can consistently pass verification tests, it is unnecessary to continue checking function parameters and supporting the debug traps. At this stage, it is advantageous to remove the DebugSupport option.
