mvc3目录下mvc4项目

[zhouyue1986]

由于业务需求，我们在站点下有部署一个二级应用，用的是ASP.NET MVC3；而后在此应用下又部署了一个三级应用，用的是ASP.NET MVC4。好了，那么问题来了，访问三级应用的页面是报错如下，还请各位帮忙看看此问题如何解决。

=======================================================
Server Error in '/mkt/spread' Application.

spread设置成单独的application，使用单独的application pool。 应该就相当于两个完全不同的程序吧。

目前是共享的程序池。

刚刚测试了一下，即使用不同的程序池也有一样的报错

有人能帮忙看下这个问题吗

各个网站里面用的mvc的dll 复制到bin里面，这样他们就各回各家各找各妈了。

[zhouyue1986]

已经尝试把引用的DLL都换成本地的了。还是不行。。。这什么情况啊

[Xanl]

你确定把mvc3的Razor.dll复制到bin目录下了？

[zhouyue1986]

是的，在项目目录中新建了一个目录，把DLL都丢进去了
