As part of a function I was writing I came up with this test to see if an assembly needed to be loaded:
if(([appdomain]::currentdomain.getassemblies() | Where{$_ -match "System.Drawing"}) -eq $null)
{
Write-Verbose "Loading System.Drawing assembly.";
[Void] [System.Reflection.Assembly]::LoadFromPartialName("System.Drawing");
}

Assemblies loaded in PowerShell
got me thinking in this direction. All I did was add the wrapper to test for a specific item. This could easily be modularized into a function:
function Load-Assembly
{
[CmdletBinding()]
param(
[Parameter(
Mandatory = $true,
ValueFromPipeline = $true
)]
[ValidateNotNullOrEmpty()]
[String]
$AssemblyName,
[Switch]
$Report = $false
)
if(([appdomain]::currentdomain.getassemblies() | Where {$_ -match $AssemblyName}) -eq $null)
{
if($Report) {
Write-Output "Loading $AssemblyName assembly.";
}
[Void] [System.Reflection.Assembly]::LoadFromPartialName($AssemblyName);
return 1
}
else
{
if($Report) {
Write-Output "$AssemblyName is already loaded.";
}
return -1
}
}
Load-Assembly -AssemblyName System.Drawing
