Hi!
I have a project which seems to cause the debugger to hang, lose track of the presence and location of breakpoints, and to return null for any statement entered into the debug console. The most notable fact about this project is that I am handling a 1MB byte array; passing that array to functions seems to cause some serious weirdness, even if I pass it by reference.

To reproduce the issue, place a breakpoint in TestClient.ps1, line 329, and step forward. Here's the code from this function ($Bytes is the 1MB byte array):

Code: Select all

function SHA1_Bytes
{
	param
	(
		[ref]$Bytes
	)
	
	$SHA1Provider = new-object -TypeName System.Security.Cryptography.SHA1Cng
	
	$SHA1Hash = [System.BitConverter]::ToString($SHA1Provider.ComputeHash($Bytes.Value))
	$SHA1Hash = $SHA1Hash.ToLower() -replace '-', ''
	
	return $SHA1Hash
}

Technically, the hang isn't really a hang - if I wait multiple minutes, it will eventually proceed.
This issue does not occur if I debug the project in PowerShell ISE.
I've attached the project to this message.

I suspect it is triggered by a hover over the variable. We will investigate and see what we can do about this.
