Support for instrumentation key ingestion will end on March 31, 2025. Please update the Readme.md file

[AnuragSingh-MSFT]

As mentioned in the doc here , support for instrumentation key ingestion will end on March 31, 2025.

The Snippet-based setup section of the doc has already been updated to include connectionString based configuration. However, the linked readme.md still has reference to ikey based setup and does not mention that "Support for instrumentation key ingestion will end on March 31, 2025".

Please include this information in the project's readme.md file as well to avoid differences between the version contained in the doc.

This is planned, and scheduled as per the March 31, 2025 guidance.
