.SYNOPSIS
Invokes an Ansible module in a new Runspace. This cmdlet will output the
module's output and write any errors to the error stream of the current
host.
.PARAMETER Scripts
[Object[]] String or ScriptBlocks to execute.
.PARAMETER Variables
[System.Collections.ArrayList] The variables to set in the new Pipeline.
Each value is a hashtable that contains the parameters to use with
Set-Variable;
Name: the name of the variable to set
Value: the value of the variable to set
Scope: the scope of the variable
.PARAMETER Environment
[System.Collections.IDictionary] A Dictionary of environment key/values to
set in the new Pipeline.
.PARAMETER Modules
[System.Collections.IDictionary] A Dictionary of PowerShell modules to
import into the new Pipeline. The key is the name of the module and the
value is a base64 string of the module util code.
.PARAMETER ModuleName
[String] The name of the module that is being executed.

Function Add-CSharpType {
<#
.SYNOPSIS
Compiles one or more C# scripts similar to Add-Type. This exposes
more configuration options that are useable within Ansible and it
also allows multiple C# sources to be compiled together.
.PARAMETER References
[String[]] A collection of C# scripts to compile together.
.PARAMETER IgnoreWarnings
[Switch] Whether to compile code that contains compiler warnings, by
default warnings will cause a compiler error.
.PARAMETER PassThru
[Switch] Whether to return the loaded Assembly
.PARAMETER AnsibleModule
TODO - This is an AnsibleModule object that is used to derive the
TempPath and Debug values.
TempPath is set to the TmpDir property of the class
IncludeDebugInfo is set when the Ansible verbosity is >= 3
.PARAMETER TempPath
[String] The temporary directory in which the dynamic assembly is
compiled to. This file is deleted once compilation is complete.
Cannot be used when AnsibleModule is set. This is a no-op when
running on PSCore.
.PARAMETER IncludeDebugInfo
[Switch] Whether to include debug information in the compiled
assembly. Cannot be used when AnsibleModule is set. This is a no-op
when running on PSCore.
