## PowerShell Module for N-Central(c) by N-Able
##
## Version : 1.4
## Author : Adriaan Sluis (as@tosch.nl)
##
## !Still some Work In Progress!
##
## Provides a PowerShell Interface for N-Central(c)
## Uses the SOAP-API of N-Central(c) by N-Able
## Completely written in PowerShell for easy reference/analysis.

## Change log
##
## v1.2 Feb 24, 2021
## -Made PowerShell 7 compatible by removing usage of WebServiceProxy.
## -Sorting CustomProperty-columns by default (NoSort/UnSorted Option available)
## -JWT-option in New-NCentralConnection
##
## v1.3 Mar 23, 2022
## -CustomProperty - Get individual Property Values. (Was list-only)
## -CustomProperty - Add/Remove individual (Comma-separated) values inside the CP.
## -CustomProperty - Optional Base64 Encoding/Decoding.
## -CustomerDetails - ValidationList for standard-/custom-property filled by API-query.
## -Enhanced Get-NCAccessGroupList/Detail
## -Enhanced Get-NCUserRoleList/Detail
##
## v1.4 May 20,2022
## -(issue) NCActiveIssueList -Status 1 and 5 were swapped. -Added NotifStateTxt-field
## -(issue) NCDeviceInfo - Multiple-values now shown comma-separated (was only showing first entry)
## -NCDeviceObject - Options to Include/Exclude categories
## -Optimized API-calls for multiple objects where supported (NCDeviceInfo and NCCDeviceObject)
## -ShowProgress option for NCDeviceInfo and NCDeviceObject using optimized API-calls.
## -Date/Time properties now have date-format (was String)
## -NCHelp shows a list of statuscodes at the bottom.
##
## v2.0 TBD
## -CP -Backup/Restore to/from JSON

# ##
# ## To Do
# ## TODO - Check for $this.IsConnected before execution.
# ## TODO - General Error-handling + customized throws.
# ## TODO - Additional Add/Set-methods
# ## TODO - Progress indicator (Write-Progress)
# ## TODO - DeviceAssetInfoExportWithSettings options (Exclude/Include) WIP
