Question

我已经在VS17中创建了WPF应用程序。我将实体框架代码优先版本6.0用于数据。我还使用了一些第三方库，例如Newtonsoft.Json和EPPlus。我通过NuGet命令行安装了所有这些工具。

当我在其中运行应用程序（带有和不带有调试）时，它按预期运行得很好。我使用简单的ClickOnce方法发布了该应用程序。该应用程序已发布，我可以对其进行设置。该应用程序启动正常。单击按钮转到应用程序的一部分后，应用程序崩溃。

我查看了Windows事件查看器，并且知道它与使用Entity Framework部署数据库有关。这是事件日志

此外，这是我的App.config文件。

<?xml version="1.0" encoding="utf-8"?>
<configuration>
  <configSections>

    <section name="entityFramework" type="System.Data.Entity.Internal.ConfigFile.EntityFrameworkSection, EntityFramework, Version=6.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" requirePermission="false" />

        <value />
      </setting>
    </FBAContentApp.Properties.Settings>
  </userSettings>
</configuration>

这是我的DbContext类

class AppContext : DbContext
{
    public DbSet<AmazonWarehouse> AmazonWarehouses { get; set; }

    public DbSet<CompanyAddress> CompanyAddresses { get; set; }

    public DbSet<Shipment> Shipments { get; set; }

    public DbSet<ShipmentBox> Boxes { get; set; }

    public DbSet<State> States { get; set; }

}

我看过的this post听起来很相似，但是我的应用程序实际上正在启动，然后移到要查询数据库的部分时崩溃。

我还应该提到我使用了Migrations（不确定是否很重要）。在Configuration.cs中，我唯一覆盖的方法是Seed（）方法来填充起始数据。

有人可以指出正确的方向吗？

如果您需要其他信息，请让我。我感谢任何愿意提供帮助的人。

编辑/更新1 根据{{3}}的建议，添加连接字符串无效。它导致应用程序在调试模式下崩溃。根据{{3}}，这是ProcessShipmentViewModel.PopulateAmazonWarehouse（）

的代码

/// <summary>
/// Grabs all AmazonWarehouses from the DbContext to populate the ListBox for the NewShipment.xaml view.
/// </summary>
private void PopulateAmazonWarehouse()
{
    using (var db = new Models.AppContext())
    {
        List<AmazonWarehouse> warehousees = db.AmazonWarehouses.Include(s => s.State).ToList();

        foreach (AmazonWarehouse amz in warehousees)
        {
            AmzWarehouseModel amzModel = new AmzWarehouseModel(amz);
            AmzWarehouses.Add(amzModel); 
           //AmzWarehouses is a List<AmazonWarehouseModel>. Which is a separate model from the Entity model (AmazonWarehouse)

        }

    }
}

Answer 1

Add following element in your [app_name].exe.config file:

<connectionStrings>
    <add name="FBAContentDB" providerName="System.Data.SqlClient" connectionString="Data Source=(LocalDB)\MSSQLLocalDB;Database=Database1;Trusted_Connection=True;MultipleActiveResultSets=true" />
</connectionStrings>

If you are using visual studio, you can:

Locate your [app_name].exe.config in debug folder
Copy connectionStrings section from debug config file and paste it to [app_name].exe.config file in your program's installation directory.

Also make sure, you 've SQL Server Local DB installed on your installation machine.

Answer 2

我遇到了同样的问题。原来是Visual Studio没有在bin / Debug和bin / Release目录中创建“ x86”和“ x64”目录。其中每个都应包含SNI.dll和SNI.pdb。当我将这些目录和文件复制并粘贴到相关目录中时，没有任何问题。

您可以使用“ F11”键盘或登录以查找错误位置

WPF应用程序在调试中运行，单击按钮后部署时崩溃
