How to get binding informations for a .Net assembly

I have a dll in the bin folder of my project and I am not able to understand why it is there.

It looks like it is not required by the project, indeed if I remove it the application runs fine. Actually, when it is开发者_运维百科 there it crash! :D

Every time I build with Visual Studio 2010 the dll is copied again.

The question is: is there a way/tool that can help me to understand who requires this dll in my app? My application is an ASP.NET MVC 2 project.

Thanks

First step is to enable the diagnostic log for the build in Visual Studio:

Tools > Options > Projects and Solutions > Build and Run

then select

MSBUild project build output verbosity : Diagnostic

This will provide a full log into your output folder. So i could get this information:

C:\MyApplication\bin\Microsoft.VisualStudio.Settings.dll
C:\MyApplication\bin\Microsoft.VisualStudio.Settings.dll
    ResolvedFrom = C:\Program Files (x86)\Microsoft Visual Studio 2010 SDK\VisualStudioIntegration\Common\Assemblies\v4.0
    CopyLocal = true
    FusionName = Microsoft.VisualStudio.Settings, Version=10.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a
    HintPath = \\Microsoft\WF4\Microsoft.VisualStudio.ActivityPack.Data.dll
    OriginalItemSpec = Microsoft.VisualStudio.ActivityPack.Data
    Version = 10.0.0.0

This tells me that the Microsoft.VisualStudio.Settings.dll is required by Microsoft.VisualStudio.ActivityPack.Data.dll

Another helpful tool is fuslogvw.exe (included in VS). It gives you full informations about an assembly origins. More informations about this tool here.
