Question

我将新开发的应用程序安装到新的PC上，并且第一次出现了ERROR，首先它需要安装.Net 4.5，我从installshield向导设置。然后出现了这个错误。如何在新PC中运行我开发的应用程序。

See the end of this message for details on invoking

WRN: Assembly binding logging is turned OFF.
To enable assembly bind failure logging, set the registry value [HKLM\Software\Microsoft\Fusion!EnableLog] (DWORD) to 1.
Note: There is some performance penalty associated with assembly bind failure logging.
To turn this feature off, remove the registry value [HKLM\Software\Microsoft\Fusion!EnableLog].

************** JIT Debugging **************
To enable just-in-time (JIT) debugging, the .config file for this
application or computer (machine.config) must have the
jitDebugging value set in the system.windows.forms section.
The application must also be compiled with debugging
enabled.

For example:

<configuration>
    <system.windows.forms jitDebugging="true" />
</configuration>

When JIT debugging is enabled, any unhandled exception
will be sent to the JIT debugger registered on the computer
rather than be handled by this dialog box.

如果我在我开发应用程序的旧电脑中安装此（ThesisCapstoneProject），它的工作正常。但在我的新电脑中，我收到了这个错误。

Answer 1

添加这2个文件。

System.Web.Extensions.Design.dll
System.Web.Extensions.dll

应该这样做，同时确保将Select Platform更改为.NET

看看here

Answer 2

检查您的参考文献，我不确定您使用的是哪种IDE，但使用Visual Studio 2012，它位于参考资料下的解决方案资源管理器中。选择MySQL对象并查看它可能的属性，因为.NET 4.5引用了更新的版本。只需卸载旧版本的MySQL.Data并添加正确的版本，从你的错误看起来你需要安装MySQL.Data版本= 6.8.3.0。

Answer 3

您需要安装MySQL和/或MySQL Connector驱动程序。以下是ODBC Connector的链接。

Connector / ODBC是适用于Windows，Linux，Mac OS X和Unix平台的标准化数据库驱动程序。

Answer 4

您的应用程序目录中是否有dll-File？也许两台计算机有不同的系统（x86与x64）。 dll-File适用于x86或x64，而不适用于两者。如果要编译“any”，x86或x64，还可以在Visual Studio中设置编译选项。

System.IO.FileNotFoundException：无法加载文件或程序集'MySql.Data，Version = 6.8.3.0
