    .SYNOPSIS
        Gets a replication server object

    .DESCRIPTION
        Gets a replication server object.

        Note: The ReplicationDatabases property gets the databases enabled for replication in the connected instance of Microsoft SQL Server/.
        Not necessarily the databases that are actually replicated.

    .PARAMETER SqlInstance
        The target SQL Server instance or instances

    .PARAMETER SqlCredential
        Login to the target instance using alternative credentials. Accepts PowerShell credentials (Get-Credential).

        Windows Authentication, SQL Server Authentication, Active Directory - Password, and Active Directory - Integrated are all supported.

        For MFA support, please use Connect-DbaInstance.

    .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.
