When I try to view attributes from .NET OPC standard client then I get

nsu=http://opcfoundation.org/UA/;i=2253
System.InvalidCastException: Cannot cast an absolute ExpandedNodeId to a NodeId. Use ExpandedNodeId.ToNodeId instead.
at Opc.Ua.ExpandedNodeId.op_Explicit(ExpandedNodeId value) in d:\UA-.NET-master\UA-.NET-master\Stack\Core\Types\BuiltIn\ExpandedNodeId.cs:line 1064
at Opc.Ua.Sample.Controls.AttributeListCtrl.Initialize(Session session, ExpandedNodeId nodeId) in d:\UA-.NET-master\UA-.NET-master\SampleApplications\Samples\Controls\Common\AttributeListCtrl.cs:line 102
at Opc.Ua.Sample.Controls.NodeAttributesDlg.ShowDialog(Session session, ExpandedNodeId nodeId) in d:\UA-.NET-master\UA-.NET-master\SampleApplications\Samples\Controls\Sessions\NodeAttributesDlg.cs:line 75
at Opc.Ua.Sample.Controls.BrowseTreeCtrl.ViewAttributesMI_Click(Object sender, EventArgs e) in d:\UA-.NET-master\UA-.NET-master\SampleApplications\Samples\Controls\Sessions\BrowseTreeCtrl.cs:line 961

in client side.
How to resolve this?

This is a problem with the client, which cannot handle ExpandedNodeId:s properly. You will need to fix the client software, most probably in AttributeListCtrl, on the line that shows up in the stack trace.

You may also wish to report this as a bug in the .NET Sample Code to OPC Foundation Github repository at https://github.com/OPCFoundation/UA-.NET
