can not import Teams PowerShell module in .net core 3.1

I tried to import the teams powershell module in .net core 3.1, windows server 2012r2, and the Microsoft.PowerShell.SDK version is 7.0.8. I can get the module via Test-ModuleManifest, but the teams module can't be imported, there is no any errors, I have tried some different teams PS gallery version like 2.3.1, 2.6.0. I can import the teams module in powershell desktop in the same windows environment. 

PSModuleInfo teamsModule = null;
using (Pipeline pipeLine = runspace.CreatePipeline())
{
Command command = new Command("Test-ModuleManifest");
//command.Parameters.Add("Path", @"C:\Program Files\WindowsPowerShell\Modules\MicrosoftTeams\2.6.0\MicrosoftTeams.psd1");
command.Parameters.Add("Path", @"C:\Program Files\WindowsPowerShell\Modules\MicrosoftTeams\2.3.1\MicrosoftTeams.psd1");
//command.Parameters.Add("Path", path);
pipeLine.Commands.Add(command);
System.Collections.ObjectModel.Collection<PSObject> psResult = pipeLine.Invoke();
teamsModule = psResult[0].BaseObject as PSModuleInfo;
}
using (Pipeline pipeLine1 = runspace.CreatePipeline())
{
Command command = new Command("Import-Module");
command.Parameters.Add("ModuleInfo", teamsModule);
command.Parameters.Add("PassThru", true);
pipeLine1.Commands.Add(command);
System.Collections.ObjectModel.Collection<PSObject> psResult1 = pipeLine1.Invoke();
}
