由于未处理的异常，该过程终止 - ＆gt;的InstallShield

Question

我构建了一个winfom桌面应用程序（Visual Studio 2013，c＃，Mssql，Entity framework 6）。 如果我在VS2013中测试应用程序运行正常，但我制作installshield包并安装它。删除此例外：

Application: myprog.exe
Framework Version: v4.0.30319
Description: The process was terminated due to an unhandled exception.
Exception Info: System.InvalidOperationException
Stack:

   at System.Data.Entity.DbContext..ctor(System.String)
   at myprog.Form1..ctor()
   at myprog.Program.Main()

导致这个？

未生成的代码是all，而不是drop exception：

try
            {
                src.DataSource = valinor.vats.Select(m => m).ToList();
                vatGridControl.DataSource = src;
            }   
            catch (Exception ex)
            {
                MessageBox.Show(ex.Message);
            }
