Windows PowerShell ISE running old version

Question

I'm writing my PowerShell scripts with Windows PowerShell ISE. When I change someting in the script and run the script, not the last saved version of the script is executed but the older one. Only if I run the script a second time it uses the current version. What can I do to always run the newest version of the script?

This is a very old question, but I think I've stumbled across the same issue. In my case I've defined a function after invoking it. It appears to work, but only because "myfunc" still has the value from the previous invocation. If you change "Hello, World!", you'll find that the new value takes affect only on the second attempt.

Invoke-Command -ScriptBlock ${function:myfunc}

function myfunc() {
    Write-Host "Hello, World!"
}

To resolve the issue, simply define the function before you attempt to call it.

function myfunc() {
    Write-Host "Hello, World!"
}

Invoke-Command -ScriptBlock ${function:myfunc}
