.NET 4.0 解决方案中的 NHibernate 1.2

我有一些基于 NHibernate 1.2 的项目，我想将它们添加到 .NET 4.0 解决方案中，但我收到 AmbigeousMatchException。
无论这些项目是针对2.0还是4.0框架。
如果我将它们添加到 .NET 3.5 解决方案中，它就会起作用。

有人有这方面的经验吗？

这是例外情况：

根据 Rup 的评论，我解决了更改 Castle DynamicProxy 1.1.5 的源并重新编译的问题。
问题是通过反射调用 System.Threading.Monitor.Enter 方法而不指定参数（这是因为在 .NET 2.0 中只有 1 个签名），但从 .NET 4.0 开始，该方法有 2 个重载。

我修改了 Castle.DynamicProxy.Builder.CodeBuilder.SimpleAST.LockBlockExpression 类，更改了行

gen.Emit(OpCodes.Call, typeof(Monitor).GetMethod("Enter"));

与行

gen.Emit(OpCodes.Call, typeof(Monitor).GetMethod("Enter", new Type[] { typeof(object) }));

我有 NHibernate 1.2 的源码来自 SourceForge http://sourceforge.net/projects/nhibernate/files/NHibernate/1.2.1.GA/NHibernate-1.2.1.GA-src.zip/download同时我用Reflector反汇编了Castle DynamicProxy 1.1.5的代码。
