Is transient thread-safe?
Because, transient services might not be designed to be thread safe. If you have to use them, then take care of multi-threading while using these services (use lock for instance). Memory leaks are generally caused by singleton services. They are not released/disposed until the end of the application.
Is Ihttpcontextaccessor thread-safe?
You’re confusing two different concepts. Thread-safety is only tangentially related to HTTP requests as an HTTP request requires the use of a thread.
Which is thread-safe when list is modified?
To put it simply, a class instance is immutable when its internal state can’t be modified after it has been constructed. A MessageService object is effectively immutable since its state can’t change after its construction. Hence, it’s thread-safe.
What is HttpContext C#?
A HttpContext object holds information about the current HTTP request. Yes each time it is created it creates a server current state of a HTTP request and response. It can hold information like, Request, Response, Server, Session, Item, Cache, User’s information like authentication and authorization and much more.
Can HttpContext be null?
HttpContext. Current is populated by IIS which is not present/active during unit testing. Hence null.
How do you implement thread safety?
There are basically four ways to make variable access safe in shared-memory concurrency:
- Confinement. Don’t share the variable between threads.
- Immutability. Make the shared data immutable.
- Threadsafe data type.
- Synchronization.
How does Dependency Injection work in a thread?
Don’t pass on dependencies by other threads. With dependency injection, you try to centralize the knowledge about the lifetime of objects. This centralized place is called the Composition Root. When you start passing dependencies from one thread to the other, those parts of the code have to know whether it is safe to pass those dependencies.
Which is the safest way to use dependency injection?
The safest way is to let each thread build a new object graph at the beginning. Don’t pass on dependencies by other threads. With dependency injection, you try to centralize the knowledge about the lifetime of objects. This centralized place is called the Composition Root.
How to use service injection in.net?
NET provides a built-in service container, IServiceProvider. Services are typically registered at the app’s start-up, and appended to an IServiceCollection. Once all services are added, you use BuildServiceProvider to create the service container. Injection of the service into the constructor of the class where it’s used.
How to avoid service locator in dependency injection?
Avoid using the service locator pattern. For example, don’t invoke GetService to obtain a service instance when you can use DI instead. Another service locator variation to avoid is injecting a factory that resolves dependencies at runtime. Both of these practices mix Inversion of Control strategies.
