c#: difference between “System.Object” and “object”
Hello,
In C# there are Object and object types. They seem to have the same functionnality, so what is the difference between the two ?

There is none. C# provides synonyms for the primitives defined by the CLR. System.String -> string, System.Int64 -> long, System.Object -> object, etc.

No difference.
object is a synomym of System.Object
It is there to allow old users to not get totally confused when they moved from an older system to this.

What do you mean by old users? The only people I've ever seen use
Object instead of object are Java programmers :)

That's what I mean. People are used to use "object" so to not force them to use "Object", they still have "object"

C# devs that started deving back on asp.net 2 and before. Every object or int I ran into was Object or Int32.
I don't believe they are different, its like the difference between System.Int32 and int... they are the same essentially.

None.
The object type is an alias for System.Object in the .NET Framework. You can assign values of any type to variables of type object.
