我遵循了 postsharp 1.5 附带的示例。我有两个简单的项目：
一个有这样的方面：
[Serializable]
public class MyAspectAttribute : OnMethodBoundaryAspect
{
public override void OnEntry(MethodExecutionEventArgs eventArgs)
{
Console.WriteLine(eventArgs.Method.Name);
base.OnEntry(eventArgs);
}
}
在另一个项目中，我有一个这样的测试用例：
public class Test
{
[MyAspect]
public void DoSomething()
{
Console.Write("aa");
}
}
在“测试”的同一个项目中，我有以下测试夹具：
[TestFixture]
public class TestFixture
{
[Test]
public void TestDoSomething()
{
var a = new Test();
a.DoSomething();
}}
由于 postsharp 异常，代码将无法编译：
Error 2 Unhandled exception: System.InvalidCastException: Unable to cast object of type 'PostSharp.CodeModel.TypeDefDeclaration' to type 'PostSharp.CodeModel.IMethod'.

我应该怎么办？
