NET frameworks are based on the. NET Framework and share core functionality of. For example, all three frameworks offer a login security model based around membership, and all three share the same facilities for managing requests, handling sessions, and so on that are part of the core ASP. NET functionality. In addition, the three frameworks are not entirely independent, and choosing one does not preclude using another. Since the frameworks can coexist in the same web application, it's not uncommon to see individual components of applications written using different frameworks.
For example, customer-facing portions of an app might be developed in MVC to optimize the markup, while the data access and administrative portions are developed in Web Forms to take advantage of data controls and simple data access.
NET Framework. NET developers that makes developing real-time web functionality easier. SignalR allows bi-directional communication between server and client. Servers can push content to connected clients instantly as it becomes available. SignalR supports Web Sockets, and falls back to other compatible techniques for older browsers. Dig deeper: What is ASP.

For more details regarding this change, see A first look at changes coming in ASP. To help close the API gap from. NET Framework to. These APIs weren't available in. NET Core 1. We recommend the following sequence of tutorials and articles for an introduction to developing ASP.
The code runs in an Azure Cloud Shell , and curl is used for testing. For those samples that make use of this approach, set the define directive at the top of the C files to define the symbol associated with the scenario that you want to run. Some samples require defining the symbol at the top of multiple files in order to run a scenario. For example, the following define symbol list indicates that four scenarios are available one scenario per symbol. The current sample configuration runs the TemplateCode scenario:.
To change the sample to run the ExpandDefault scenario, define the ExpandDefault symbol and leave the remaining symbols commented-out:. For more information on using C preprocessor directives to selectively compile sections of code, see define C Reference and if C Reference. Some sample apps contain sections of code surrounded by region and endregion C directives. The documentation build system injects these regions into the rendered documentation topics. Region names usually contain the word "snippet.
