部署失败：CLR 触发器

Question

我正在尝试部署基于 .Net 4.0 构建的 CLR 触发器，但将目标框架更改为 3.0，但我收到以下错误消息。

------ 部署开始：项目：ServiceClient，配置：调试任何 CPU ------ 构建于 2012 年 1 月 18 日下午 2:16:24 开始。 SqlClr部署： 开始将程序集 ServiceClient.dll 部署到服务器 WS037298：custDB 如果部署为与 SQL Server 目标实例不兼容的 .NET Framework 版本构建的 SQL CLR 项目，则可能会出现以下错误：“部署错误 SQL01268：为程序集创建程序集失败，因为程序集验证失败”。要解决此问题，请打开项目的属性，然后更改 .NET Framework 版本。 生成的部署脚本： D:\Visual Studio 2010\Projects\ServiceClient\ServiceClient\bin\Debug\ServiceClient.sql

正在创建 [ServiceClient]... D:\Visual Studio 2010\Projects\ServiceClient\ServiceClient\bin\Debug\ServiceClient.sql(39-39): 部署错误 SQL01268: .Net SqlClient 数据提供者: Msg 6503, Level 16, State 12, Line 1 Assembly 'system .servicemodel，版本=3.0.0.0，文化=中性，publickeytoken=b77a5c561934e089。在 SQL 目录中找不到。 执行批处理时出错。

构建失败。

Answer 1

已明确说明 - 它需要 System.ServiceModel 程序集，但未提供。尝试先将此程序集（可能还有其他程序集）部署到 sql server

并尝试将您的静态字段作为局部变量移动到触发器主体中。

如果您将程序集标记为 UNSAFE 并将数据库标记为 TRUSTWORTHY - 可能无需这些修改即可工作
