[ShreyasJejurkar]

Below are the warnings

Here is the corresponding rule -> https://docs.microsoft.com/en-gb/dotnet/fundamentals/code-analysis/quality-rules/ca1844

I am by no means a performance expert and do not have a good machine to compare and test perf score, so I am filing this issue so that one can from the team figure out what to do here!
There is a total of 14 warnings.
