Hello.

For QuickOPC 2018.3, you need to target and use at least .NET Franework 4.6.2: opclabs.doc-that.com/files/onlinedocs/QuickOpc/2018.3/User%2...me.html#dotNET%20Runtimes.html .

Best regards

Good morinig,

Winforms
Framework 4.6.1
Visual Studio 2017
.NET UA tecnology



private void B_InviaRicetta_Click(object sender, EventArgs e)
{
var easyUAClient = new EasyUAClient();


// Modify value of a node
easyUAClient.WriteValue(
"opc.tcp://pcc127:62841/Sipro/uaPLUS",
"nsu=http://opcfoundation.org/Advosol/uaPLUS;ns=2;s=Dev1.Data.vq6994",
TB_Ricetta.Text);
}


This is the exeption

System.TypeLoadException: 'The type' OpcLabs.EasyOpc.UA.EasyUAClient 'in the assembly' OpcLabs.EasyOpcUA, Version = 5.54.1151.1, Culture = neutral, PublicKeyToken = 6faddca41dacb409 'has the' OnDeserializedMethod 'method with an incorrect signature for the serialization attribute with which it is decorated. '
