Static properties across different ASP.NET requests

Question

If I create a static property MyLanguage and one request sets its value to 1, while at the same time another thread sets it to 2 - what will be the final value of MyLanguage?

Does the single MyLanguge property gets shared across ASP.NET sessions?

Answer 1

A static property/field is shared across the app domain. So all your sessions should see the same value.

The only exception is when you use the ThreadStatic attribute on a static field, in which case each thread will see its own value. e.g.

[ThreadStatic]
static int counter = 0; // each thread sees a different static counter.

Answer 2

It would be 2. Static fields, properties are shared between objects.So Latest set values will be updates for all the instances.

From MSDN

Use the static modifier to declare a static member, which belongs to the type itself rather than to a specific object. The static modifier can be used with classes, fields, methods, properties, operators, events, and constructors, but it cannot be used with indexers, destructors, or types other than classes.
