Visual Studio将找不到引用

Question

I'm working with some application handed over by another person in which I must document the requirements, build and deploy processes.

The problem here is that Visual Studio (2005) is throwing a lot of errors since it can't find the references for the dlls. This obviously won't let VS build the project.

Everything works fine on the persons computer but not on mine, even though the project references the same folder where the dlls are, the bin folder.

How can I circumvent these problems and get VS to properly reference the dlls?

The following printscreen shows the references screen for the project.

Answer 1

My guess is that your DLL uses a more recent .NET framework than your application does.

Check the properties for your DLL source (right-click on the DLL code in the solution explorer and choose Properties). Go to Application - Target .NET framework and compare the version to the one the application itself uses (right-click on the project code). Note: under your application properties check both the settings under Application - Target .NET framework AND under Publish - Prerequisites.

For what it's worth, even after changing the .vbproj file and removing many lines about hard coded values, I eventually checked out the project again removed all references to the given DLL and then added it using the GUI.

Lesson learned, don't try to change out one DLL for a newer version without using VB2005 GUI. The easiest solution will probably be to transfer everything to another project. It will be incredibly time consuming to find where visual studio has left the hard coded path at.

WOOT!!!! Compile the DLL file to a lower version of the .NET framework, and it will fix the problem!!!!

Answer 3

The paths in the project file cannot be the same or the assemblies referenced have a different version.

It might be worth unloading your project and the editing it to inspect where it's looking and for what version.

Answer 4

I had the same problem with an older Visual Studio Project that I opened in Visual Studio 2008. I tried to add new references to the project and got permanent errors that the dll's cannot be found. After the migration of the Project to Visual Studio 2010 I got the following error message when I tried to add a new reference:

'mySample.dll' or one of its dependencies, requires a later version of the .NET Framework than the one specified in the project. You can change ...

After changing the projects .NET Framework to a newer version everything works fine.

Good suggestions in other answers. In my case, it was because the libraries weren't copied (downloaded) successfully: the files existed, but were 0 kB.

干净了，删除了所有的DLL然后VS2008抱怨它找不到引用（Duh !!!）并且不会重建....幸运的是我有了旧版本的dll并将其替换为目录然后做了重建以取代他们......现在所有参考都可以，我们恢复正常......好老VS 2008
