Research direction

The issue reports that the 'Inline temporary variable' refactoring in Visual Studio produces incorrect output when the variable has multiple assignments. To fix this, one needs to locate the relevant code in the Roslyn repository, likely in the 'Features' project under refactoring providers. Look for the InlineTemporary refactoring implementation, understand how it currently handles variable declarations with subsequent assignments, and adjust the logic to properly combine the initial value and subsequent assignment into a single expression.
