NET features:. NET Compatibility Mode. NET impersonation has been enabled for the application. If ASP. NET impersonation and WCF impersonation are both enabled for a particular service operation, the service implementation ultimately runs using the identity obtained from WCF.
This value defaults to false if not specified. Because ASP. NET Compatibility Mode implies request processing semantics that are fundamentally different from the WCF default, individual service implementations have the ability to control whether they run inside of an application for which ASP. NET Compatibility Mode has been enabled. The default value for this attribute is Allowed. IIS 7. Such a configuration generates an activation exception when the service receives its first message.
For more information about enabling ASP. The Model in an MVC application represents the state of the application and any business logic or operations that should be performed by it. Business logic should be encapsulated in the model, along with any implementation logic for persisting the state of the application.
Strongly-typed views typically use ViewModel types designed to contain the data to display on that view. The controller creates and populates these ViewModel instances from the model. Views are responsible for presenting content through the user interface. They use the Razor view engine to embed. There should be minimal logic within views, and any logic in them should relate to presenting content. If you find the need to perform a great deal of logic in view files in order to display data from a complex model, consider using a View Component , ViewModel, or view template to simplify the view.
Controllers are the components that handle user interaction, work with the model, and ultimately select a view to render. In an MVC application, the view only displays information; the controller handles and responds to user input and interaction.
In the MVC pattern, the controller is the initial entry point, and is responsible for selecting which model types to work with and which view to render hence its name - it controls how the app responds to a given request.
Controllers shouldn't be overly complicated by too many responsibilities. To keep controller logic from becoming overly complex, push business logic out of the controller and into the domain model. If you find that your controller actions frequently perform the same kinds of actions, move these common actions into filters. The ASP. NET Core. It gives you full control over markup, supports TDD-friendly development and uses the latest web standards. This enables you to define your application's URL naming patterns that work well for search engine optimization SEO and for link generation, without regard for how the files on your web server are organized.
You can define your routes using a convenient route template syntax that supports route value constraints, defaults and optional values. Convention-based routing enables you to globally define the URL formats that your application accepts and how each of those formats maps to a specific action method on a given controller. When an incoming request is received, the routing engine parses the URL and matches it to one of the defined URL formats, and then calls the associated controller's action method.
Attribute routing enables you to specify routing information by decorating your controllers and actions with attributes that define your application's routes. This means that your route definitions are placed next to the controller and action with which they're associated. As a result, your controller logic doesn't have to do the work of figuring out the incoming request data; it simply has the data as parameters to its action methods.
The validation attributes are checked on the client side before values are posted to the server, as well as on the server before the controller action is called. The framework handles validating request data both on the client and on the server. Validation logic specified on model types is added to the rendered views as unobtrusive annotations and is enforced in the browser with jQuery Validation. In ASP. Your app can also use dependency injection in view files , using the inject directive:.
Connect to the Serial Console, open a PowerShell instance , and then follow these steps. Download the appropriate update to a new or existing data disk that is attached to a working VM from the same region:. Attach the system disk to a recovery VM. Make sure that the disk is flagged as Online in the Disk Management console. Note the drive letter that is assigned to the attached system disk. In the subkey, examine the DriverVersion value that is the driver version of the network adapter of the VM.
Detach the system disk, and create the VM again. If you still need help, contact Azure Support to get your issue resolved quickly. Skip to main content.
