.Net WebService get error when using TransactionOption.RequiresNew

I have a WebService project using .Net Framework 2.0. I'm migrating to .Net Framework 4.7.2. Current source code is declaring WebMethods as below:

import System.EnterpriseServices ... <WebMethod(TransactionOption:=TransactionOption.RequiresNew)> Public Function LoginUpdate(ByVal Lv_UserId As String) As String

When it's execute SQL query, I receive an error:

An attempt was made to load a program with an incorrect format. (Exception from HRESULT: 0x8007000B)

When I use other Transaction Option: Disabled, Not Supported, Supported, it's working. I receive an error when i use Required and Requires New. Please help me.
