I have the below code which works perfectly works with Visual Studio 2010,
string path = @"Path_to_XML.xml";
FileStream stream = new FileStream(path, FileMode.Open, FileAccess.Read);
XmlReaderSettings settings = new XmlReaderSettings
{
ValidationType = ValidationType.Schema
};
settings.Schemas.Add(@"REQUIRED_NAMESPACE",
@"REQUIREDSCHEMA.xsd");
But when used with Visual Studio 2017, it fails to add schema; ie., Fails in the line,
settings.Schemas.Add(...)
with below exception,
$exception {"The parameter is incorrect. (Exception from HRESULT: 0x80070057 (E_INVALIDARG))"} System.ArgumentException

How to resolve this issue?
Note: The only difference I see is the System.XML.dll is referred from .Net 4.6.2 in VS 2017 and in VS 2010, it is referred from .Net 4.0.
