asp.net-mvc – 尝试执行多项目ASP.Net MVC站点时出现编译错误

This error points out that two references have the same assembly
identity because the assemblies in question lack strong names,they
were not signed,and thus the compiler has no way of distinguishing
between them in metadata. Thus,the run time ignores the version and
culture assembly name properties. The user should remove the redundant
reference,rename one of the references,or provide a strong name for
them.

可以解释如下.

下面的示例创建一个程序集并将其保存到根目录.

// CS1704_a.cs
// compile with: /target:library /out:c:cs1704.dll
public class A {}

下面的示例创建一个与前一个示例同名的程序集,但将其保存到其他位置.

// CS1704_b.cs
// compile with: /target:library /out:cs1704.dll
public class A {}

下面的示例尝试引用两个程序集.以下示例生成CS1704.

// CS1704_c.cs
// compile with: /target:library /r:A2=cs1704.dll /r:A1=c:cs1704.dll
// CS1704 expected
extern alias A1;
extern alias A2;

UPDATE

如果两个程序集都是强名称(签名),则CLR将始终从GAC加载.

您可以按照以下步骤操作：

1. Determines the correct assembly version by examining applicable
   configuration files,including the application configuration file,
   publisher policy file,and machine configuration file. If the
   configuration file is located on a remote machine,the runtime must
   locate and download the application configuration file first.

2. Checks whether the assembly name has been bound to before and,if so,
   uses the previously loaded assembly. If a previous request to load the
   assembly failed,the request fails immediately without attempting to
   load the assembly.

3. Checks the global assembly cache. If the assembly is found there,the
   runtime uses this assembly.

4. Probes for the assembly (for more info check below mentioned article )
