我们更新了所有NuGet软件包后,MVC应用程序崩溃了.在尝试了所有内容后,我创建了一个新的MVC应用程序,更新了NuGet包和基本导航栏...

<div class="navbar navbar-inverse navbar-fixed-top">
    <div class="container">
        <div class="navbar-header">
            <button type="button" class="navbar-toggle" data-toggle="collapse" data-target=".navbar-collapse">
                <span class="icon-bar"></span>
                <span class="icon-bar"></span>
                <span class="icon-bar"></span>
            </button>
            <a class="navbar-brand" href="/">Application name</a>
        </div>
        <div class="navbar-collapse collapse">
            <ul class="nav navbar-nav">
                <li><a href="/">Home</a></li>
                <li><a href="/Home/About">About</a></li>
                <li><a href="/Home/Contact">Contact</a></li>
            </ul>

<ul class="nav navbar-nav navbar-right">
    <li><a href="/Account/Register" id="registerLink">Register</a></li>
    <li><a href="/Account/Login" id="loginLink">Log in</a></li>
</ul>


        </div>
    </div>
</div>

......看起来像这样......

...然后点击图标......

可能导致这种情况的任何想法？

尝试手动将Bootstrap.css和Bootstrap.js添加到_Layout.vbhtml,但没有区别

谢谢

我们有一个Win Forms应用程序,它生成带有iTextSharp的pdf,将其保存到本地目录,然后应用程序打开该文件.有一个客户(所有XP盒和Adobe Reader 11),它会抛出以下错误

No application is associated with the specified file for this operation
at System.Diagnostics.Process.StartWithShellExecuteEx(ProcessStartInfo startInfo)
at System.Diagnostics.Process.Start()

这表明Adobe Reader与pdf扩展名没有正确关联,除了他们可以导航到本地目录并打开文件而没有任何问题.

有没有人遇到过这种奇怪之处？

编辑ZippyV - 典型子的例子

 Public Sub PDF_Functions_LogCalls_RunReport(ByVal Customer As Boolean)
    Try
        Dim vOutput As String = LogCalls_Run(Customer)
        If Left(vOutput, 5) = "Error" Then
            TaskDialog.Show(MainForm, AppBoxError("File Error", vOutput, "Error"))
            Exit Sub
        End If
        If System.IO.File.Exists(vOutput) Then
            Dim P As New Process
            P.StartInfo.FileName = vOutput
            P.StartInfo.Verb = "Open"
            P.Start()
        End If
    Catch ex As Exception
        EmailError(ex)
        Exit Sub
    End Try …

我们刚刚将 .NET 4.6 项目升级到 .NET 4.8，并且此功能

Private Function MeasureTextSize(ByVal text As String, ByVal fontFamily As FontFamily, ByVal fontStyle As FontStyle, ByVal fontWeight As FontWeight, ByVal fontStretch As FontStretch, ByVal fontSize As Double) As Size

    Dim ft As New FormattedText(text, System.Globalization.CultureInfo.CurrentCulture, FlowDirection.LeftToRight, New Typeface(fontFamily, fontStyle, fontWeight, fontStretch), fontSize, Brushes.Black)
    Return New Size(ft.Width, ft.Height)
End Function

显示以下警告

warning BC40000: 'Public Overloads Sub New(textToFormat As String, culture As CultureInfo, flowDirection As FlowDirection, typeface As Typeface, emSize As Double, foreground As Brush)' is obsolete: …
