MVC cache dependency: file dependency, mvc cache dependency File "1" indicates cache dependencies. File dependencies mean that I have not set the cache expiration time.

Dependency graph (Dependency graph)At any time, a file depends on another file, and Webpack this as a dependency between the files.This allows Webpack to receive non-code resources (Non-code Asset) (example or Web fonts), and can use them as dependencies to provide to your application.Webpack start with a list of modules defined in the command line or configurati

-express). For all versions of Microsoft SQL Server from 7.0 to 2005, you can use polling technology. Since these tutorials are using SQL Server 2005 Express, we will focus on establishing and using polling. For more information about the notification features of SQL Server 2005, refer to the more Reading Materials section at the end of this tutorial. When polled, you configure the database to include a table named AspNet_SqlCacheTablesForChangeNotification, which has three columns – TableName,

Role: It guides us in how to properly resolve dependencies between modules, and it is also the core principle of framework design. The essence of the dependency inversion principle is to require the relationship between classes to be based on an abstract interface. Robert Martin describes in this way the dependency inversion principle [Martin 1996]: The traditional strategy is to "divide and conquer" the

3.2. "Hollywood Principles"Looking at the previous description of the dependency injection concept, we refine the core idea of dependency injection. If the traditional coupling between components, such as new, Factory mode, is a developer's initiative to build dependent objects, then the dependency injection mode is its reverse, that is, passively waiting for som
