Where can I get SDK 5.0b?

This article describes my issue exactly and mentions that it is fixed in SDK 5.0b.

It even includes a link to the installer.

Unfortunatly the link is broken (404 error).

Can someone point me towards SDK 5.0b (even if it is still in beta).

Please just get the newest, if solved in 5.0b it will also be in newer versions.
