Can't find NuGet.Server.DataServices.Packages

Feb 7, 2012 at 12:11 PM

Following the instructions to host my own NuGet server, I created an blank ASP.NET Web Application project and added the NuGet.Server package to it.  According to the package manager, I have:

  • Id: NuGet.Server
  • Version: 1.6.1

However, when I look at NuGet.Server.dll in my project References, the properties show it is version

Even more confusing, when I run, the failure references NuGet.Server version

System.TypeLoadException was unhandled by user code

  Message=Could not load type 'NuGet.Server.DataServices.Packages' from assembly 'NuGet.Server, Version=, Culture=neutral, PublicKeyToken=null'.
  Source=NuGet.Server  TypeName=NuGet.Server.DataServices.Packages
       at NuGet.Server.NuGetRoutes.MapRoutes(RouteCollection routes)
       at NuGet.Server.NuGetRoutes.Start() in C:\Workspace\NuGet\NuGet.Server\DataServices\Routes.cs:line 15

As a NuGet newb, this is thoroughly confusing me.  Any pointers?

The package version and the assembly version aren't necessarily reved together. The latest NuGet.Server is so you're good there.

Could you print what your msbuild log says msbuild MyServer.csproj /v:N and what version of the NuGet.Server is being loaded into your AppDomain once you run the application (Debug -> Windows -> Show Modules)?

Here's the MSBuild output:

The modules show NuGet.Server as "version":

My guess is the assembly name of the project you are building is "NuGet.Server". When you compile your application, it ends up overwriting the binary from the package since the output files are named the same. Just pick a different name for your project or a different output assembly name.

Now it's obvious!  Thank you so much for pointing that out!
