是否有可能实现.NET库二进制兼容性？ [英] Is it possible to achieve binary compatibility in .NET library?

问题描述

我有一个.net库的COM可见的，它是从VB6的应用程序调用。

I have a .NET library visible in COM, and it's called from a vb6 application.

如果我添加一些方法，并发布一个新版本（但不要删除或更改现有方法的签名），我希望能够仅仅将其安装在生产设备，并有工作。然而，似乎这种做法行不通;我需要reompile VB6的应用程序。

If I add some methods and release a new version (but don't erase or change signatures of existing methods), I would like being able to just install it in the production machine, and have it working. However, it seems that such approach doesn't work; I need to reompile the vb6 application.

有什么办法来实现这一目标？

Is there any way to achieve this?

推荐答案

您可以明确地使用的 的Guid 你的COM接口和类和的 DISPID 你的方法，字段和属性的属性：

You can explicitly use the Guid attribute on your COM interfaces and classes and the DispId attribute on your methods, fields and properties:

[Guid("0E213759-1679-4CD1-8322-566CF76928EF")]
public class SampleClass
{
    [DispId(8)]
    public void MyMethod() {}
}
