At present, VBA is the only embedded language you can use in
Excel (or any other Office program). MS hasn't announced any
plans to support other languages without VSTO.

Hello

I would like to use C# to code against excel workbooks instead
of VBA.

I am aware of the existence of Visual Studio Tools for Office
but it doesn't fit
my needs.

Visual Studio tools for office creates a DLL that is accessed
by the workbook.

Will a future version of excel support C# in such a way that it
would be
possible to embed the source code as part of the XLS file? Does
Visual Studio
Tools for office already allow this?

Thanks Alex
