I found the problem  Instead of adding a class   cs  file by mistake I had added a Web API Controller class which added a configuration file in my solution  And that configuration file was looking for the mentioned DLL  Microsoft Web Infrastructure 1 0 0 0   It worked when I removed that file  cleaned the application and then published

Was facing the same issue and unfortunately nothing here was working  Finally  I came across this link  https   blogs msdn microsoft com jjameson 2009 11 18 the-copy-local-bug-in-visual-studio   Turns out the solution is sort of dumb  set copy-local for the microsoft web infrastructure dll to False  then set it back to True    By the way  I think what is happening is that there are two versions of the microsoft web infrastructure dll  one that is pre-installed in the GAC  and another one that is now a nuget package  I think one is masking the other  hence causing issues  In my particular case  on my build server  I need it to be copied over to a folder  this folder is then zipped and sent off to deployment   I guess the system had a copy locally and just thought  nah  it ll be fine

I had the same problem   When I tried the accepted answer  rockyb   I got the message that the package was already installed and assigned to my project   When I checked the references list  it was NOT referenced  however   The Microsoft Web Infrastructure was installed in my solution s packages folder   Instead of using NuGet to add the package  I just used the Add Reference option   On the left side of the pop-up window  I chose Browse  and then pressed the Browse button on the bottom of the window   I navigated to the packages folder under the folder that my solution was in  then drilled down to the     mysolution packages Microsoft Web Infrastructure 1 0 0 0 lib net40 and clicked on the Microsoft Web Infrastructure dll   After clicking OK  the package showed up in my References list   I used the Web Deploy Package option to deploy my website and everything worked

Why not copy Microsoft Web Infrastructure dll file manually to the server BIN folder  This works for  My project is VS2010 Website   This file can be located   C  Program Files  x86  Microsoft ASP NET ASP NET MVC 4 Packages Microsoft Web Infrastructure 1 0 0 0 lib net40  Just copy and paste it in the BIN folder   You probably need to include this in the web config if you don t have it already    lt compilation debug  true  targetFramework  4 0  gt     lt assemblies gt       lt add assembly  Microsoft Web Infrastructure  Version 1 0 0 0  Culture neutral  PublicKeyToken 31BF3856AD364E35   gt     lt  assemblies gt   lt  compilation gt    Reference  http   thedeveloperblog com

I had the same problem after upgrading a bunch of NuGet packages  I have tried all kinds of deleting  cleaning  resintalling described here and beyong to no avail   The references did not have Microsoft Web Infrastructure despite the NuGet manager showed it was installed    The problem was solved by replacing      lt package id  Microsoft Web Infrastructure  version  1 0 0 0  targetFramework  net45    gt    with      lt package id  Microsoft Web Infrastructure  version  1 0 0 0  targetFramework  net46    gt    in packages config   The culprit is apparently  net45

It appears that Microsoft Web Infrastructure dll is not being installed in the GAC  even if  net  4 0 or 4 5 or other  are installed successfully on Windows Server  On localhost  typically Windows client   it seems like it is being in the GAC when the tools platform  Visual Studio etc   are installed    As one possible fix  please try the following    Run the following command in the Package Manager Console   If you are using Visual Studio  this can be reached via menu options  Tools --  Library Package Manager --  Package Manager Console    PM gt  Install-Package Microsoft Web Infrastructure   You will see the following messages if it is successfully installed   Successfully installed  Microsoft Web Infrastructure 1 0 0 0   Successfully added  Microsoft Web Infrastructure 1 0 0 0  to Web   You will notice that Microsoft Web Infrastructure dll has now been added as a Reference  can be seen in the references folder of your project in in Solution Explorer  If you look at the properties of this reference you will notice that  Copy Local  has been set to  True  by default  Now when you  Publish   your project  Microsoft Web Infrastructure dll will be deployed

Update-Package -reinstall Microsoft Web Infrastructure didn t work for me  as I kept receiving errors that it was already installed   I had to navigate to the Microsoft Web Infrastructure 1 0 0 0 folder in the packages folder and manually delete that folder   After doing this  running Install-Package Microsoft Web Infrastructure installed it   Note  CopyLocal was automatically set to true
