What COM-compatible language would you recommend for writing a small plugin?

Question

Programming

I would like to write a plug-in for SolidWorks. The entire API is available through either COM or PIA. Accordingly, I want to understand which language is best suited.
Options:
* D - I like the language, it seems that COM should “eat” correctly, but you will have to write your own CComPtr analogues or something like that.
* Intel C++ is a poor language, but very frisky libraries and the best toolset for development and profiling. (Don't offer Microsoft C++ or C++/CLI - don't care.)
* C# - good for UI but not good for performance at all, if you use it, you still have to use it in conjunction with Intel C++ via P/Invoke.
In general, any comments are welcome!

Answer 1

Intel C ++ is a compiler, not a language, it will just result in machine code more optimized for their processors.
I disagree that C++ is squalor.
After all, C# makes it very easy to connect COM components, and works with them almost like with its own assemblies.
So, I would probably choose C++ if you need a fast independent plugin, and C# if you need to make the plugin itself faster. And since, as far as I understand, you are profiling in C #, then this is the most suitable option. Well, if wrappers are written for a C++ lib, then I would prefer an intermediate C++/CLI lib, because there are too many factors to consider when writing a wrapper in C#, and it's not always easy, for example, if you want to pass an array of strings.
I don't know about D. Judging by the description in the wiki, it fits well, but whether COM will eat is a question. A quick google search didn't turn up an example. Maybe you should start writing in D, if not weak difficulties suddenly appear, switch to another.
