Pattern: Use of empty catch block

Issue: -

Description

Empty catch blocks are considered a poor design choice as they result in the errors occurring in a try block not being acted upon.

While this does not inherently lead to issues, they should be avoided wherever possible.

How

Use Write-Error or throw statements within the catch block.

Example of incorrect code:

try
{
	1/0
}
catch [DivideByZeroException]
{
}

Example of correct code:

try
{
	1/0
}
catch [DivideByZeroException]
{
	Write-Error "DivideByZeroException"
}

try
{
	1/0
}
catch [DivideByZeroException]
{
	Throw "DivideByZeroException"
}
