Here is a pre-version of the forth-comming Bass.Net v22.214.171.124: www.un4seen.com/filez/4/Bass24.Net_pre.zip
This build already contains four Bass.Net assembly versions (each in a seperate sub-folder):
.\v2.0 : Bass.Net for .Net 2.0
.\v4.0 : Bass.Net for .Net 4.0
.\compact : Bass.Net CE for .Net CompactFramework 3.5
.\iphone : Bass.Net iPhone for .Net CompactFramework 3.5
The final version will contain the exact same assemblies but contain a re-worked help system.
Note: There is no need to supply a dedicated version for .Net 3.5, as it is still based on the .Net 2.0 version and just contains various additions.
AS such you can always use the .Net 2.0 Bass.Net version with the .Net 3.5 framework!
