问题描述
我有一个包含三个程序集的 C# 控制台应用程序:Main、Common 和 Utilities.
I have a C# console application with three assemblies: Main, Common and Utilities.
在 Main 程序集的文件 Main.cs 中，我有一行:
In a file in the Main assembly, Main.cs, I have the line:
using Utilities;
在 Common 程序集中的目录中，我有 DLL IBM.Data.DB2.dll.
In a directory within the Common assembly, I have the DLL IBM.Data.DB2.dll.
在 Utilities 程序集中，我有一个源模块可以访问上述 dll.实用程序具有对 IBM.Data.DB2 的引用.在此程序集中的源文件 Util.cs 中，我有一行:
In the Utilities assembly, I have a source module which accesses said dll.Utilities have a Reference to IBM.Data.DB2.In a source file within this assembly, Util.cs, I have the line:
using IBM.Data.DB2;
如果在此文件中的某个方法中，我对 DB2 程序集中的代码进行了任何引用，如下所示:
If, within a method in this file, I make any reference to code within the DB2 assembly, as in:
DbConnection c = new DB2Connection( _connectString );
编译 Main 程序集时出现错误，指出找不到命名空间名称 Utilities.Utilities 无论有没有这条线都可以很好地编译.如果我注释掉上面的行，一切都编译得很好.
I get an error compiling the Main assembly stating that the namespace name Utilities can not be found. Utilities compiles fine with or without the line. If I comment out the above line, everything compiles fine.
推荐答案
一位乐于助人的同事过来帮我解决了这个问题，大约五秒钟.
A helpful colleague came by and solved this for me in about five seconds.
事实证明，默认情况下，当在 VS 2010 中创建新的控制台应用程序时，它会获得.NET Framework 4 Client Profile"的目标框架.将其更改为.NET Framework 4"即可解决问题.
Turns out that by default, when a new Console app is created in VS 2010, it gets a target framework of ".NET Framework 4 Client Profile". Changing this to ".NET Framework 4" made the problem go away.
