What is the namespace 'Standard'?

Question

When I try to write a new using clause, I notice that Intellisense has, in its list, a namespace called Standard. However, this seems to have no members on closer inspection. What is this namespace?

It it part of your own project? – Refuel

No, I'm pretty sure, as I opened up another project, and it was still there. EDIT: It seems to appear in EVERY WPF project, but not on any other projects. – Alp

I can confirm it seems like a valid namespace on my machine too, putting a using Standard; doesn't cause any errors in a WPF application – Saratov

I don't see it when I start a new WPF application, and get a build error if I try to use it anyway. Using Studio 2010 / .NET 4. – Lipoprotein

@JeremyWiggins Seems to be a 4.5 namespace, according to the answer. – Alp

Try searching for 'standard' in Visual Studio's object browser (found under the 'view' menu) – Bataan

Answer 1

There is a namespace in the PresentationFramework assembly called "Standard". All of its types are internal though, so you can't see any of the types. However, you can still use the namespace.

The namespace seems to have appeared in the 4.5 reference assembly, it doesn't appear in the 4.0 one.
