How to change the Read Only Attribute of Files in Powershell using a Visual Studio Pre-Build command (ie not using the DOS attrib command)

When using Microsoft PowerShell 2.0, you can just put this in your Visual Studio project pre-build event to remove the read-only attribute on binary files:

$(ProjectDir)FixTemplateFolderAttributes.cmd $(ProjectDir)
This points to a command file in your project directory called "FixTemplateFolderAttributes.cmd" like so:

:: Changes file attributes as needed.
cd %1
powershell Set-ExecutionPolicy RemoteSigned
powershell ../Build/Scripts/FixTemplateFolderAttributes.ps1

This calls the following powershell commands to make files writable:

$computer = gc env:computername

$fileList = Get-ChildItem ".\InfoPath Form Template" | Where-Object {$_.name -like "*.dll" -or $_.name -like "*.pdb" -or $_.name -like "*.xsf"  }

foreach ($fileItem in $fileList) 
{
 $fileItem.set_IsReadOnly($false) # Remove readonly flag
}

$fileList = Get-ChildItem ".\obj\Debug\" | Where-Object {$_.name -like "*.dll" -or $_.name -like "*.pdb" -or $_.name -like "*.txt"}

foreach ($fileItem in $fileList) 
{
 $fileItem.set_IsReadOnly($false) # Remove readonly flag
}

$fileList = Get-ChildItem ".\bin\Debug\" | Where-Object {$_.name -like "*.dll" -or $_.name -like "*.pdb" -or $_.name -like "*.txt"}

foreach ($fileItem in $fileList) 
{
 $fileItem.set_IsReadOnly($false) # Remove readonly flag
}
