VB.NETのイミディエイトウィンドウのインテリセンスが不安定？

ソリューションを開く、イミディエイトウィンドウを開く、入力してもインテリセンスは出ない。
ブレークポイントなど置いてステップイン、エディターがデバッグモードになるとインテリセンスが出る。
その後はデバッグ中止して、普通の状態でも出る。
一度ソリューションを閉じて開く、デバッグ開始しなくても出る。
もう一度閉じて開くと出なくなる。
IDE再起動はもちろん出なくなる。

シンボルをローカルに置いても同じ症状。
4Kモニターのスケーリングを変えても同じ。

あまり困ることはないけど気になります。
visual studio2019で win10でもwindows server2019でも同様です。

VBAからExcelを操作2

前回の

            Call Ary関数
            For j = 0 To UBound(Ary関数, 1)
 
                For I = 1 To UBound(Ary関数, 2)
                    objCells(j + 1, I + 2) = Ary関数(j, I)
                Next
            Next

Call Ary関数

For j = 0 To UBound(Ary関数, 1)

For I = 1 To UBound(Ary関数, 2)

objCells(j + 1, I + 2) = Ary関数(j, I)

この部分耐えがたい遅さです。
vb.netの二次元配列はまあまあ我慢できますがVBAはデータが多くなるとだめです。
一次元目の要素（項目数）が少なければ一次元配列を並べた方が速いです。
さらに速いのはレコードセットから直接ループさせつつ書き込む。
すごく速いのでvb.netもデータテーブルから直接書き込むようにしました。
プロセスも今の所残っていません。コードが冗長になりますけど。

VBAからExcelを操作

VBAからもできるでしょうと思ったけど・・

    Public Function Excelbinding()
        Dim objExcel As Object
        Dim objExApp As Object

Set objSheets = Nothing

Set objSheet1 = Nothing

Set objSheet2 = Nothing

Set objSheet3 = Nothing

Set objWorkbook = Nothing

Set objWorkbooks = Nothing

end function

今までは意識してなかったけどVBAではオブジェクト解放は要らない？
プロセスは残らないが・・
とりあえずset=nothingで安心することに。

vb.net から Excel を操作

以前ここでExcel出力のことを書いたけど
裏技的で推奨できない。
正攻法で行くことにしました。
Excel参照設定もクライアント環境で違うでしょうから依存しない実行時バインディングで・・
excelのプロセスが残らないようにするのが大変でした
まずは単純に開いて5秒待って閉じるだけ

    Public Shared Sub Excelmain2()
        Dim objExcel As Object = Nothing
        Dim objExApp As Object = Nothing
        Dim objWorkbook As Object = Nothing
        Dim objWorkbooks As Object = Nothing
        Dim fpath As String
        fpath = "xlsファイルのパス"

        Try
            objExcel = CreateObject("Excel.Application")
            objExApp = objExcel.Application
            objExApp.Visible = True
            objWorkbooks = objExApp.Workbooks
            objWorkbook = objWorkbooks.Open(fpath)

            System.Threading.Thread.Sleep(5000)

            objExcel.DisplayAlerts = False

            Marshal.ReleaseComObject(objWorkbook)
            Marshal.ReleaseComObject(objWorkbooks)
            objExApp.Quit()
            objExcel.DisplayAlerts = True
            Marshal.ReleaseComObject(objExApp)
            Marshal.ReleaseComObject(objExcel)

            objWorkbook = Nothing
            objWorkbooks = Nothing
            objExApp = Nothing
            objExcel = Nothing
        Catch ex As Exception
            Throw

        End Try
    End Sub

Public Shared Sub Excelmain2()

Dim objExcel As Object = Nothing

Dim objExApp As Object = Nothing

Dim objWorkbook As Object = Nothing

Dim objWorkbooks As Object = Nothing

Dim fpath As String

fpath = "xlsファイルのパス"

Try

objExcel = CreateObject("Excel.Application")

objExApp = objExcel.Application

objExApp.Visible = True

objWorkbooks = objExApp.Workbooks

objWorkbook = objWorkbooks.Open(fpath)

System.Threading.Thread.Sleep(5000)

objExcel.DisplayAlerts = False

Marshal.ReleaseComObject(objWorkbook)

Marshal.ReleaseComObject(objWorkbooks)

objExApp.Quit()

objExcel.DisplayAlerts = True

Marshal.ReleaseComObject(objExApp)

Marshal.ReleaseComObject(objExcel)

objWorkbook = Nothing

objWorkbooks = Nothing

objExApp = Nothing

objExcel = Nothing

Catch ex As Exception

開いて閉じるだけでも変数が多くて混乱します
次に開いてセルに文字代入して保存して閉じる。
