Method not found: Microsoft.Data.SqlTypes.SqlVector`1.get_Null()'

[frankbuckley]

Using version 6.1.0:

// <PackageReference Include="Microsoft.Data.SqlClient" Version="6.1.0" />

using Microsoft.Data.SqlTypes;

Console.WriteLine(SqlVector<float>.Null.IsNull);

Results in:

Unhandled exception. System.MissingMethodException: Method not found: 'Microsoft.Data.SqlTypes.SqlVector`1<!0> Microsoft.Data.SqlTypes.SqlVector`1.get_Null()'.
   at Program.<Main>$(String[] args)

Is it because?...

Here, the return value is not defined as nullable:

SqlClient/src/Microsoft.Data.SqlClient/netcore/ref/Microsoft.Data.SqlClient.cs

Lines 133 to 134 in b89ac49

	/// <include file='../../../../doc/snippets/Microsoft.Data.SqlTypes/SqlVector.xml' path='docs/members[@name="SqlVector"]/Null/*' />
	public static SqlVector<T> Null => throw null;

While here, the return value is defined as nullable:

SqlClient/src/Microsoft.Data.SqlClient/src/Microsoft/Data/SqlTypes/SqlVector.cs

Lines 107 to 108 in b89ac49

	/// <include file='../../../../doc/snippets/Microsoft.Data.SqlTypes/SqlVector.xml' path='docs/members[@name="SqlVector"]/Null/*' />
	public static SqlVector<T>? Null => null;

(And this was not updated when SqlVector became a value type.)

@frankbuckley Thanks for opening the issue and proposing the fix. We have a test that should have caught this. We are working on fixing this.
