Targets Excel users who write VBA code for functions and macros, and would like to start using .NET. An additional audience is C/C++ -based .xll add-in developers who want to use the .NET framework to develop their add-ins.
The integration is done by an Excel Add-In (.xll) that exposes .NET code to Excel. The user code can be in text-based (.dna) script files (Visual Basic or C#), or compiled .NET libraries from any language.
ExcelDna allows exporting functions and commands from .NET scripts or compiled libraries. ExcelDna also supports automatic marshaling for calling the Excel C API from .NET, making it easier to port existing C/C++ code that uses the native Excel API. Access to the Excel automation interfaces is available from ExcelDna, and can be used late-bound from Visual Basic, or via a reference to the primary interop assemblies.
