function Get-DbaSqlInstanceProperty {
    <#
.SYNOPSIS
Gets SQL Instance properties of one or more instance(s) of SQL Server.
 
.DESCRIPTION
 The Get-DbaSqlInstanceProperty command gets SQL Instance properties from the SMO object sqlserver.
 
.PARAMETER SqlInstance
SQL Server name or SMO object representing the SQL Server to connect to. This can be a collection and receive pipeline input to allow the function
to be executed against multiple SQL Server instances.
 
.PARAMETER SqlCredential
PSCredential object to connect as. If not specified, current Windows login will be used.
 
.PARAMETER EnableException
        By default, when something goes wrong we try to catch it, interpret it and give you a friendly warning message.
        This avoids overwhelming you with "sea of red" exceptions, but is inconvenient because it basically disables advanced scripting.
        Using this switch turns this "nice by default" feature off and enables you to catch exceptions with your own try/catch.
