Passport service then authenticates the user details on the sign-in page and sees if they are valid, stores them on the client machine, followed by redirecting the user to the requested page. Caching refers to storing the data temporarily in the memory so that it can be accessed from the memory instead of having to search for it in the original location. Caching enhances the efficiency of the application and increases its speed. There are mainly three types of caching including page caching, fragment caching, and data caching.

Personalization, control state and view state information is saved. This stage can be handled by overriding the Render method or creating a Page_Render handler. LoadViewState LoadViewState event allows loading view state information into the controls. Init Init event initializes the control property and the control tree is built. This event can be handled by overloading the OnInit method or creating a Page_Init handler.

As the name suggests, with regard to scoped services, they are created within a scope. The scope is typically the lifetime of an HTTP request, but not necessarily always. I, as a developer, might create custom scopes in code, but anyone should be careful to use this technique sparingly.

Code written in C# or Visual Basic .NET will, when compiled, run only in the CLR, which provides functionalities such as garbage collection and memory management. The advantage of this is that managed code is platform-independent because it runs in the CLR rather than the operating system of the machine accessing the application. Web services communicate by using standard web protocols and data formats — including HTTP, XML and SOAP — allowing them to connect across different platforms and programming languages. The .NET Framework provides built-in classes for building and consuming web services. ASP.NET is an open-source web application framework developed by Microsoft and it is the subset of the .NET framework, the successor of the classic Active Server Pages. Here, we have made a list of the top 50 ASP.NET interview questions along with their answers.

While one application pool is servicing a request, you cannot route the request to another application pool. However, you can assign applications to another application pool while the server is running. You can obfuscate your code by using a new precompilation process called ‘precompilation for deployment’. This process builds each page in your web application into a single application DLL and some placeholder files. A .NET developer produces code using .NET languages such as VB, .NET, and C#. They typically design codes and tests to debug and implement software applications.

Post your jobs & get access to millions of ambitious, well-educated talents that are going the extra mile. When CAS is applied to assemblies, the assembly can be viewed as partially trusted. The tool is crucial for developers as it enables them to manipulate feeds from other sites which results in faster and easier loading compared to SML or RSS feeds.

List The Events In Page Life Cycle

Additionally, if developers will have access to sensitive data, make sure to assess them for ethics and trustworthiness. IL stands for Intermediate Language, which is an object-oriented programming language that is a partially compiled code that .NET developers will then compile to native machine code. Code written in unsupported languages, such as Java, will produce unmanaged code, meaning developers can’t rely on the CLR to provide this kind of portability.

In a .NET interview, a strong candidate should be able to highlight the advantages of the Model-View-Controller architectural pattern.

The CLR allows you to run multiple .NET applications in the same application domain. It is an abbreviation for Language Integrated Query, which was introduced in Visual Studio 2008. LINQ is a set of functions that extend the capabilities of queries to the .NET framework language syntax that allows you to manipulate data regardless of the data source.

It includes one or more scripts on the Microsoft web server before sending the request to the user. When ASP.NET pages run, it goes through several steps of the life cycle, which performs a series of actions like initialization, running, restoring, and rendering. Microsoft released ASP.NET in 2002 to build dynamic websites and web applications using the .NET framework. ASP.NET decides whether to compile it or serve it from a cache. If a huge amount of data is stored, loading the page may take longer than required. A local resource is explicit to a specific page, which is the one in particular who can get to it, while global resources can be accessed from any place.
