Description
Remove logging of solution content in Release builds. This logging used to be valuable for diagnostics in past, but we haven't seen issues that need this information in a while.
The logging slows down project loading.
Customer Impact
Significantly improves dotnet-watch initialization, especially on large solutions.
On a solution with 4,500 files the project load time is reduced by 75s (46%): from 164s to 89s.
Regression?
Regression compared to 8.0. The logging was added in 9.0.
Risk
Justification: The impact is limited to sending Hot Reload messages to browser and the change is trivial.
Verification
