.net - Is the C# language a Microsoft product? -

I am certifying my thesis and I am thinking that how should I describe that language

C # and Microsoft

C # and Microsoft (C #)

C-Secret (C #)

C # . Net Framework

Combination, or something else? The C # language is an ECMA standard introduced by Standard Hewlett-Packard, Intel and Microsoft and

It was developed within Microsoft. The standard does not use the term "Microsoft C #", so I initially label it as "" C # Programming Language developed by Microsoft "and later I only call it " C # " or "C # programming language" , as standard ().
