Hi,

I am a developer very happy Ext.NET.

I convinced a my big customer to use EXT.NET for its internal development and since it is a new project we would like to start to develop with the latest version.

I know that there is a release of EXT.NET 4.x later this year.

Can you tell me if there is a preview that you can use right away?

If you do not have a version 4.x, purchasing the license for EXT.NET 3.x now you can move on to 4 when it becomes available without buying a new license?
