I'm trying to setup a build for a .Net MVC project in TeamCity. I followed the steps described here: How to build ASPNET applications in TeamCity

But the build is still failing. The error messages I have are 

App_Start\BundleConfig.cs(2, 18): error CS0234: The type or namespace name 'Optimization' does 

not exist in the namespace 'System.Web' (are you missing an assembly reference?) 
App_Start\FilterConfig.cs(2, 18): error CS0234: The type or namespace name 'Mvc' does not exist in the namespace 'System.Web' (are you missing an assembly reference?) 
App_Start\RouteConfig.cs(5, 18): error CS0234: The type or namespace name 'Mvc' does not exist in the namespace 'System.Web' (are you missing an assembly reference?) 
Controllers\HomeController.cs(5, 18): error CS0234: The type or namespace name 'Mvc' does not exist in the namespace 'System.Web' (are you missing an assembly reference?)

Controllers\HomeController.cs(23, 16): error CS0246: The type or namespace name 'ActionResult' could not be found (are you missing a using directive or an assembly reference?)

I have all the references with Copy Local = true and True in the csproj. TeamCity is downloading correctly the nuget packages but it seems that is not using them. All I can see is that in the .csprojResolveAssemblyReference file in obj/Release there is the following line:

C:\Program Files (x86)\Reference Assemblies\Microsoft\Framework.NETFramework\v4.5.1\System.Web.dll

So, it seems that is using that file and not the file in the nuget folder.

What do I have to do to have the build up and running?

Thank you very much.

  • I have this exact same problem, but with TFS instead of TeamCity, so I'd be interested in seeing what the possible solution is to this. – Brendan Green Nov 27 '14 at 01:23

You need to add a step to your build process to restore all NuGet packages. See here for instructions.

System.Web.Optimization namespace is not in the System.Web.dll assembly. It's got its own assembly, System.Web.Optimization.dll. Add that DLL as a reference. If you don't have that DLL, get it via NuGet. I think this is the correct package.

  • I have System.Web.Mvc and System.Web.Optimiztion referenced via NuGet, and TeamCity is dowloading both packages. I don't understand why it doesn't look for them in the packages folder. – vgaltes Nov 27 '14 at 09:27
  • Try copying the DLL's manually to the bin folder. I've had it fail to do it automatically before. – mason Nov 27 '14 at 13:43
  • No luck. I think I'm going to re-install the machine and try again. – vgaltes Dec 01 '14 at 21:19

I've finally solved the problem. What I did is to upload the NuGet packages to the source code repository and remove the NuGet step in the TeamCity configuration. Actually, I prefer this option to be able to work in my code although NuGet was down.

Thank you very much.
