引用多级DLL时，Visualstudio IDE中的Filenotfoundexception [英] Filenotfoundexception in visualstudio IDE when multilevel DLL's are referenced
问题描述
您好，
我的环境是：
- Windows 7，VS 2010 SP1，FW .NET 4.0。
问题是：
- 我有一个DLL .NET（没有StrongName的dll1.dll版本1.0.0.0），它包含一个简单的类，可以执行任何操作;
- 我有第二个DLL .NET（没有StrongName的dll2.dll版本1.0.0.0），它包含一个WinForms UserControl，带有一个简单的Button控件;还引用了dll1，将SpecificVersion属性设置为false;
- 我有一个WinForms应用程序，它只包含一个Form。 dll1和dll2在SpecificVersion属性设置为false的情况下引用，在VS IDE中，我在ToolBox中添加UserControl，然后在表单上拖放一个UserControl实例;
此时，应用程序编译（x86）和运行时都可以。
然后：
- 我修改了一下在dll1中的位代码，我将dll1的版本从1.0.0.0修改为1.1.0.0，我重新编译dll1;
- 但我不想重新编译dll2因为他的代码没有变化;
- 在WinForms应用程序中，对dll1的引用升级到1.1.0.0，对dll2的引用仍然是1.0.0.0。
结果：
- 编译仍然可以;
- 运行时仍然可以，因为没有StrongName;
- 但是当我尝试在IDE中显示表单时，VS会抛出一个FileNotFoundException，因为它找不到dll1 version 1.0.0.0。
我不明白为什么，在设计n时间，VS会抛出这个在运行时没有抛出的异常。
我希望我的解释清晰而详细。
谢谢你的帮助

我的尝试： < br $> b $ b
使用VisualStudio 2013，同样的问题。
Hello,
my environment is :
- Windows 7, VS 2010 SP1, FW .NET 4.0.
The issue is :
- I have a DLL .NET (dll1.dll version 1.0.0.0 without StrongName) who contains a simple class that does anythis ;
- I have a second DLL .NET (dll2.dll version 1.0.0.0 without StrongName) who contains a WinForms UserControl, with one simple Button control ; dll1 is also referenced, with SpecificVersion property set to false ;
- I have a WinForms application, who contains just one Form. dll1 and dll2 are referenced with SpecificVersion property set to false, and in the VS IDE, I add the UserControl in the ToolBox, then I drag and drop one instance of UserControl on the Form ;
At this point, application compilation (x86) and runtime are OK.
Then :
- I modify a little bit code in dll1, I modify the version of dll1 from 1.0.0.0 to 1.1.0.0, and I recompile dll1 ;
- BUT I DON'T WANT to recompile dll2 because his code has no changes ;
- In the WinForms application, reference to dll1 is upgraded to 1.1.0.0, and reference to dll2 is still to 1.0.0.0.
Results :
- compilation is still OK ;
- runtime is still OK, because there is no StrongName ;
- BUT when I try to display the Form in the IDE, VS throws a FileNotFoundException because it cannot found "dll1 version 1.0.0.0".
I don't understand why, at design time, VS throws this exception that is not thrown at runtime.
I hope that my explanations are clear and detailed enough.
Thank you for your help

What I have tried:
With VisualStudio 2013, same issue.
推荐答案
很可能VS编辑器嵌入了版本的dll某处。
尝试从表单和工具箱中删除控件，然后重新添加;应该摆脱错误。
It is likely the VS editor has embedded the version of the dll somewhere.
Try deleting the control from the form and from the toolbox, and add it again; that should get rid of the error.
你好，
我有这个但是我得到了同样的错误。
这是导致异常的dll2和dll1之间的链接，而不是应用程序和dll2之间的链接。

Hello,
I have trid that but I get the same error.
This is the link between dll2 and dll1 that causes the exception, and not the link between application and dll2.
