I have started learning C# and was looking for a standard specification, but found that C# versions greater than 2.0 were not standardized by ISO or ECMA (or so I gathered from Wikipedia). Is there any reason for this?

Because writing, reviewing, validating, publishing, processing feedback, revising, re-publishing etc complex specification documents takes significant time and effort, which is a finite resource - and the demand for an ISO / ECMA version of the specification hasn't been sufficient to prompt Microsoft into investing that time.
The non-Microsoft compiler authors (Mono etc) seem to be doing just fine without it.
Anecdotally, it also avoids the problem where 2 specifications say different conflicting things (which can happen, and has happened).

@Jude precisely; that is the c# 2 version from 2006. The question is: why nothing since? – Marc Gravell May 23 '15 at 10:00

ECMA-334:2022 has published June 2022，which is based on C# 6.0
Microsoft has opensourced C# standardization on github and is still working on C# 7.0 Standard.
