Exporting functions in C#

[Alexander Filatov]

I need implementing Windows Cluster Resource DLL, that requires me creating
DLL exporting several functions. How it can be done in C#?

Thanks,
Alexander

You can create a DLL that implements an interface such as
IWEExtendContex tMenu or IWEExtendProper tySheet and access it as a COM object
but you cannot use a C# DLL as you would a C++ DLL.

Implement your interfaces and register the DLL for COM interop in the
project build properties.

Hi Alexander,

Based on my understanding, you want to create a managed dll which exports
function to unmanaged code.
I think you can create a managed dll and create a COM wrapper for it. The
article below tells you how to do COM wrapper:

Hi, Jeffrey!

As far as I know, COM dlls exports several predefined functions such as
DllRegisterServ er, DllCanUnload etc. How can I export function with other
name (clustering API requires me exporting Start function)? Or... may be I
miss your thought?

The second link solves exact problem, but it is too awkward developing
application is such a way :(. Do you know, is this problem will be addressed
in next C# version?

Thanks a lot,
Alexander.

You can't build Cluster resource dll's using C#, native C++ is your only
option. You should even consider (yet) using any of the managed languages
for this kind of system level programming, the CLR overhead is too large for
things like device drivers, cluster resources ...., unless you don't mind a
workingset foot-print of ~8MB.
