Description
Currently
DisposeObjectsBeforeLosingScopeanalyzer always allocates aConcurrentDictionary<K, V>when it's initialized. As it's used to avoid reporting duplicate diagnostics for the same location, it's only needed when there are rule violations in code.Suggested improvement
Defer dictionary allocation until it's actually needed in the case when rule violations are detected. This should avoid the allocation for successful builds.
Testing
All unit tests for this analyzer passed.
