ConnectionFailureException when user running the command does not match the ConnectAsUserName

$Credential = Get-Credential -Message "Enter your login name" 
Import-Module -Name SqlServer
$ServerInstance = "SERVERNAME"
$Server = New-Object Microsoft.SqlServer.Management.Smo.Server $ServerInstance
$Server.ConnectionContext.LoginSecure = $true
$Server.ConnectionContext.ConnectAsUser = $true
$Server.ConnectionContext.ConnectAsUserName = $Credential.GetNetworkCredential().UserName
$Server.ConnectionContext.ConnectAsUserPassword = $Credential.GetNetworkCredential().Password
try {$Server.ConnectionContext.Connect()} catch {$_.Exception | Format-List -Force}

Throws the following error, when the user running the command does not match the ConnectAsUserName

从提供的 PowerShell 复现步骤以及堆栈跟踪中的 ConnectionManager.InternalConnect 和 SqlConnection.Open 路径开始。检查当 ConnectAsUser 与调用方不同时，SqlServer 22.3.0 的依赖项集合是如何加载的，尤其是缺失的 System.Diagnostics.StackTrace 程序集。只要同一脚本能够成功连接，或能够明确识别底层依赖项问题，即可视为完成。
