• If this is a security issue, I have read the security issue reporting guidance.

Summary

When the debugger breaks inside a function which sets a new value for a variable that was already set in the parent scope, a Watch pane expression monitoring that variable shows the value from the parent scope instead of the value from the current, function scope.

This behavior was previously reported in #1219.

Steps to Reproduce

Consider the following script that sets and outputs the value of a $scope variable before, inside, and after a function call:

function Write-Scope
{
	Write-Host -Object "$`scope: $scope"
}
function Foo
{
	Write-Scope
	$scope = 'Foo'
	Write-Scope
}
$scope = 'script'
Write-Scope
Foo
Write-Scope

The script writes the following text to the console:

$scope: script
$scope: script
$scope: Foo 
$scope: script

As seen in the attached screenshot, when the debugger breaks after a new value is assigned to $scope inside the Foo function, the expression $scope in the Watch pane still evaluates to the value from the parent scope ("script"). The expected value for $scope ("Foo") is displayed in the following locations:

• Inside the Local variable group of the Variables pane.
• After hovering the cursor over the $scope token in the code editor.
• After evaluating the expression $scope in the Terminal.
