= Ensure data integrity in COM =
In order to instruct the components to use RPC_C_AUTHN_LEVEL_PKT_INTEGRITY for the COM authentication level ([https://msrc.microsoft.com/update-guide/vulnerability/CVE-2021-26414 CVE-2021-26414]), you can use the following ''appsettings.json'' file:
<syntaxhighlight lang="json">
{
  "OpcLabs.BaseLib.Runtime.InteropServices.ComManagement": {
    "Configuration": {
      "SecurityParameters": {
        "EnsureDataIntegrity": true
      }
    }
  }
}
</syntaxhighlight>

= Set the default URL of the OPC UA Global Discovery Server (GDS) =
In order to set the default URL of the OPC UA Global Discovery Server (GDS) used by QuickOPC global discovery operations, you can use the following ''appsettings.json'' file:
<syntaxhighlight lang="json">
{
  "OpcLabs.EasyOpc.UA.EasyUAClient": {
    "InstanceParameters": {
      "GdsEndpointDescriptor": {
        "UrlString": "opc.tcp://opcua.demo-this.com:58810/GlobalDiscoveryServer"
      }
    }
  } 
}
</syntaxhighlight>
= Use NET API implementation of OPC Data Access client =
<syntaxhighlight lang="json">
{
  "OpcLabs.EasyOpc.DataAccess.EasyDAClient": {
    "InstanceParameters": {
      "EnableNativeClient": false,
      "EnableNetApiClient": true
    }
  } 
}
</syntaxhighlight>

If your project involves user interface, it needs to be configured too:
<syntaxhighlight lang="json">
{
  "OpcLabs.EasyOpc.DataAccess.EasyDAClient": {
    "InstanceParameters": {
      "EnableNativeClient": false,
      "EnableNetApiClient": true
    }
  },

  "OpcLabs.EasyOpc.DataAccess.Forms.Browsing.DADialog": {
    "ClientSelector": {
      "InstanceParameters": {
        "EnableNativeClient": false,
        "EnableNetApiClient": true
      }
    }
  }
}
</syntaxhighlight>
