NHibernate的1.2在.NET 4.0解决方案 [英] NHibernate 1.2 in a .NET 4.0 solution

问题描述

我有一个基于NHibernate的1.2的一些项目，我想将它们添加到一个.NET 4.0的解决方案，但我得到一个AmbiguousMatchException。
不管这些项目是针对2.0或4.0的框架。
它的工作原理，如果我把它们添加到一个.NET 3.5的解决方案。

有没有人有经验吗？

下面是例外：

解决方案

随着RUP的评论，我决定改变城堡DynamicProxy 1.1.5和重新编译的来源。
问题是调用与反思方法System.Threading.Monitor.Enter不指定参数（这是因为在.NET 2.0中只有1签字），但由于.NET 4.0的方法有2重载。

我已经修改了类Castle.DynamicProxy.Builder。codeBuilder.SimpleAST.LockBlockEx pression，更改行

  gen.Emit（欧普codes.Call的typeof（监视器）.GetMethod（回车））;
 

与行

  gen.Emit（欧普codes.Call的typeof（监视器）.GetMethod（回车，新类型[] {typeof运算（对象）}））;
 

我有NHibernate的1.2 from SourceForge上的同时，我拆开城堡DynamicProxy 1.1.5与反射的code。

I have some projects based on NHibernate 1.2 and I'd like to add them to a .NET 4.0 solution, but I get an AmbiguousMatchException.
No matter if these projects are targeted to 2.0 or 4.0 framework.
It works if I add them to a .NET 3.5 solution.

Does anyone have experience with that?

Here is the exception:

解决方案

Following Rup's comment, I resolved changing the sources of Castle DynamicProxy 1.1.5 and recompiling.
The problem is invoking with reflection the method System.Threading.Monitor.Enter without specifying arguments (that's because in .NET 2.0 there is only 1 signature), but since .NET 4.0 that method has 2 overloads.

I've modified the class Castle.DynamicProxy.Builder.CodeBuilder.SimpleAST.LockBlockExpression, changing the row

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

with the row

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

I've got the sources of NHibernate 1.2 from SourceForge while I disassembled the code of Castle DynamicProxy 1.1.5 with Reflector.
