I am tasked with requirements for the production machine (Server 2008 R2), and am wondering if this project setup would work with only .NET 4.0 installed and IIS 7 for WCF Service. Is .NET 3.5 needed to load assemblies that that are targeted to it?

A VS2010 solution contains several projects:

Projects targeted to .NET 3.5:

  • Model (DTO) classes
  • Business Logic Layer
  • Data Access Layer
  • Interfaces for BLL and DAL

Projects targeted to .NET 4.0:

  • WCF Service project wrapping BLL methods

In development, there's 2.0, 3.5 and 4.0 installed on the machine and everything works fine with WCF hosted in IIS6.0

默认情况下，Server 2008 R2 安装了 .Net Framework v2.0.50727，但您可以使用以下方式安装 .NET 3.5 Sp1：Server Manager -> Features -> .Net Framework 3.5.1 Features. 如果使用 .NET 3.5 编译，我认为 .NET 4.0 客户端不足以运行您的 BLL

如果其他人遇到同样的问题：

不需要 .NET 3.5，因为已发布的 DLL 只需安装 .NET2 和 .NET4 即可正常运行。

面向 .NET4 的 WCF 服务在 IIS 7.0 下运行正常，无需修改或特殊配置。
