TypedTableBase Constructor

[aiba7339]

I'm using Visual Studio 2017 C# and created some DataTables in a DataSet.
There are some codes generated by VS and some of them are TypedTableBase construcotrs.
They are in a DataSet.Designer.cs file and two constructors are defined.
The one is below.
They refers DataSet object in given DataTable, however, DataSet object is always null when I run my codes, so I catch a null reference exception when I try to create TypedTableBase object from DataTable object.
If I comment out their "if" sentences, it runs.
Is this VS's bug?

    internal FeaturesDataTable(global::System.Data.DataTable table) {
        this.TableName = table.TableName;
        if ((table.CaseSensitive != table.DataSet.CaseSensitive)) {
            this.CaseSensitive = table.CaseSensitive;
        }
        if ((table.Locale.ToString() != table.DataSet.Locale.ToString())) {
            this.Locale = table.Locale;
        }
        if ((table.Namespace != table.DataSet.Namespace)) {
            this.Namespace = table.Namespace;
        }
        this.Prefix = table.Prefix;
        this.MinimumCapacity = table.MinimumCapacity;
    }

It doesn't work correctly just commenting out "if" sentences.

@aiba7339 Please provide more details on what you mean by, "There are some codes generated by VS."

@ajcvickers Thank you for asking.

When I add a DataSet in my project, .xsd file is added in it, for example "DataSetTest.xsd".
Moreover, "DataSetTest.Designer.cs" file is automatically generated by VS.
It has some constructors as I defined some DataTable s in the dataset.
One of them is like I wrote above.
