How to get SDK:
- Download and install TortoiseSVN source control software.
- Create a new folder. You will need around 2 GB of free space.
- Right click the folder and choose "SVN Checkout..." option.
- In Checkout window set "URL of repository" to: http://xp-dev.com/svn/fonline_sdk/ and click OK.
- Wait for SDK to download (it will take a while).
This way you will create a local copy of SDK repository on your computer.
You can always update it by right-clicking the repository folder and choosing "SVN Update" option.
