Hello.

Please send over the whole minimal project to reproduce it. Your code appears fine; the fact that the error appears probably has to do with Blazor etc.

My code:

public void Browse_Servers()
{
var client = new EasyDAClient();
ServerElementCollection serverElements;
try
{
serverElements = client.BrowseServers(TagService.IP_Win_List);
}
catch (OpcException opcException)
{
Console.WriteLine("*** Failure: {0}", opcException.GetBaseException().Message);
return;
}

foreach (ServerElement serverElement in serverElements)
{
Console.WriteLine($"ServerElements(\"{serverElement.ClsidString}\").ProgId: {serverElement.ProgId}");
using (StreamWriter sw = File.AppendText(CommonClass.error_path))
{
sw.WriteLine($"ServerElements(\"{serverElement.ClsidString}\").ProgId: {serverElement.ProgId}" + " " + Convert.ToString(DateTime.Now));

}
}
}
