应用程序在启动时崩溃 - 缺少 Microsoft.VisualBasic.PowerPacks [英] Application crashes on startup - missing Microsoft.VisualBasic.PowerPacks

问题描述

我编写了一个简单的 VB.NET 应用程序，它在开发机器上运行良好.

I wrote a simple VB.NET application which works fine on the development machine.

然而，在另一台机器上，即使安装了 .NET Framework，它在启动时也会崩溃，并出现 System.InvalidOperationException.

However on another machine, even though the .NET Framework is installed, it crashes on startup with System.InvalidOperationException.

它在查找 Visual Basic 程序集时似乎有问题.

There seems to be a problem with it finding the Visual Basic assemblies.

这是失败之一(我用三个点替换了敏感信息):

Here is one of the fails (I replaced sensitive information with three dots):

*** Assembly Binder Log Entry  (16/06/2013 @ 15:45:12) ***

The operation failed.

推荐答案

PowerPacks 缺失的原因并不清楚，.NET 4 客户端配置文件可能是一个问题.周围有多个版本的 PowerPack，版本编号变得一团糟.在我的机器上，相同的版本被报告为 v2.0.50727，即使它作为版本 10.0 存储在 GAC 中

It isn't that clear why PowerPacks is missing, the .NET 4 Client Profile could be an issue. There have been multiple versions of PowerPacks around and the version numbering got to be a mess. On my machine, that same version is reported as v2.0.50727, even though it is stored in the GAC as version 10.0

最好的办法是回到你的项目.单击解决方案资源管理器"窗口中工具栏上的显示所有文件"图标.现在显示参考节点.展开它并选择 PowerPacks 参考.在属性"窗口中，将复制本地"属性更改为 True.

Best thing to do is to go back to your project. Click the "Show All Files" icon on the toolbar in the Solution Explorer window. That now shows the References node. Expand it and select the PowerPacks reference. In the Properties window, change the Copy Local property to True.

重新构建，您的构建目录现在将拥有 DLL 的副本.将其与 EXE 一起复制到目标机器上.

Rebuild and your build directory now will have a copy of the DLL. Copy it along with the EXE onto the target machine.
