SqlProgrammability provider fails to update/bulk copy into tables with computed persistent columns

Description

SqlProgrammability provider fails to update/bulk copy into tables with computed persistent columns - you get exception when you call update method:
System.Data.NoNullAllowedException: Column '{persistentColumn}' does not allow nulls.

Repro steps

Please provide the steps required to reproduce the problem

1. Create table:

CREATE TABLE [dbo].[T1](
	[A] [int] NOT NULL,
	B  AS ((0)) PERSISTED NOT NULL
)

2. Step B

type Database = SqlProgrammabilityProvider<"name=someConnectionString">
let t = new Database.dbo.Tables.T1()
t.AddRow(3)
t.Update() 

Expected behavior

New row is inserted into the table.

Actual behavior

System.Data.NoNullAllowedException: Column 'B' does not allow nulls.

Known workarounds

Following code can be used - works for update only:

    let t = new Database.dbo.Tables.T1()
    let r = t.NewRow(3)
    r.["B"] <- 0
    t.Rows.Add(r)
    t.Update()

Start with the SqlProgrammability provider's generated table and row update paths, using the supplied T1 schema and AddRow/Update reproduction. Compare the update and bulk-copy flows, then verify that inserts into tables with computed persistent columns complete without a NoNullAllowedException.
