实体框架程序集中的重复类型名称 (6.1.0) [英] Entity Framework Duplicate type name within an assembly (6.1.0)

问题描述

我不确定发生了什么，但在执行查询时我不断收到以下异常.程序集中的重复类型名称."我一直无法在网上找到解决方案.我通过从解决方案中的所有项目中删除实体框架并使用 nugget 重新安装来解决该问题.然后突然之间异常又回来了.我一遍又一遍地验证了我的表模式，并没有发现任何问题.

I am not sure what is going on but I keep getting the following exception when doing a query. "Duplicate type name within an assembly." I have not been able to find a solution on the web. I had resolved the issue by removing entity framework from all the projects in the solutions and re-installing using nugget. Then all of the sudden the exception is back. I have verified my table schema over and over and find nothing wrong with.

这是导致异常的查询.

    var BaseQuery = from Users in db.Users
            join UserInstalls in db.UserTenantInstalls on Users.ID equals UserInstalls.UserID
            join Installs in db.TenantInstalls on UserInstalls.TenantInstallID equals Installs.ID
            where
                Users.Username == Username
                && Users.Password == Password
                && Installs.Name == Install
            select Users;

    var Query = BaseQuery.Include("UserTenantInstalls.TenantInstall");

    return Query.FirstOrDefault();

正如我之前提到的，同样的查询之前也有效.数据没变，代码没变.

As I mentioned previously the same query was working before. The data has not changed and the code has not changed.

推荐答案

作为一种变通方法，只有在您使用调试器单步执行时才会发生这种情况.如果您将断点放置在源代码内部的几行下方，则不会显示错误.

As a work around, this only happens if you are single-stepping using the debugger. If you place your break point a few lines further down inside your source, the error will not show up.

我还没有卸载，这至少可以让我继续工作.

I haven't uninstalled, and this at least allows me to continue working.
