Session is a method to save the session state of users and web applications. ASP.NET Core provides a middleware for managing session state. This article mainly introduces the use of Session in Asp.net Core. If you are interested You can learn more about it. Preface 2017 started quietly. 2017 is another particularly important year for me. During the New Year's Day holiday, I wrote an Asp.net Core verification code to log in at home. I encountered two small problems during the demo process. The first was to reference the dll in Asp.net Core. In the past, we referenced the DLL directly. In the Core This is not possible. It must be added based on NuGet or based on project.json. Then saving VS will start restoring the class library. The second is the problem of using Session. To use Session in Core, you need to add the Session class library. Add Session to your project based on NuGet: Microsoft.AspNetCore.Session. Modify startup.cs in s

8. PHP correctly understands the cookie and session mechanism
Introduction: Correctly understand cookie and session mechanisms The difference and connection between cookie and session mechanisms in php Specifically, the cookie mechanism uses a solution that maintains state on the client side. It is a storage mechanism for session state on the user side. It requires the user to turn on cookie support on the client side. The role of cookies is an effort to solve the stateless defects of the HTTP protocol. The session mechanism uses a solution that maintains state between the client and the server. At the same time, we also see,

To start C#.NET development, you need to: 1. Understand the basic knowledge of C# and the core concepts of the .NET framework; 2. Master the basic concepts of variables, data types, control structures, functions and classes; 3. Learn advanced features of C#, such as LINQ and asynchronous programming; 4. Be familiar with debugging techniques and performance optimization methods for common errors. With these steps, you can gradually penetrate the world of C#.NET and write efficient applications.

The relationship between C# and .NET is inseparable, but they are not the same thing. C# is a programming language, while .NET is a development platform. C# is used to write code, compile into .NET's intermediate language (IL), and executed by the .NET runtime (CLR).

C#.NET is still important because it provides powerful tools and libraries that support multiple application development. 1) C# combines .NET framework to make development efficient and convenient. 2) C#'s type safety and garbage collection mechanism enhance its advantages. 3) .NET provides a cross-platform running environment and rich APIs, improving development flexibility.

C# and .NET adapt to the needs of emerging technologies through continuous updates and optimizations. 1) C# 9.0 and .NET5 introduce record type and performance optimization. 2) .NETCore enhances cloud native and containerized support. 3) ASP.NETCore integrates with modern web technologies. 4) ML.NET supports machine learning and artificial intelligence. 5) Asynchronous programming and best practices improve performance.

The programming process of C# in .NET includes the following steps: 1) writing C# code, 2) compiling into an intermediate language (IL), and 3) executing by the .NET runtime (CLR). The advantages of C# in .NET are its modern syntax, powerful type system and tight integration with the .NET framework, suitable for various development scenarios from desktop applications to web services.

C# is a modern, object-oriented programming language developed by Microsoft and as part of the .NET framework. 1.C# supports object-oriented programming (OOP), including encapsulation, inheritance and polymorphism. 2. Asynchronous programming in C# is implemented through async and await keywords to improve application responsiveness. 3. Use LINQ to process data collections concisely. 4. Common errors include null reference exceptions and index out-of-range exceptions. Debugging skills include using a debugger and exception handling. 5. Performance optimization includes using StringBuilder and avoiding unnecessary packing and unboxing.
