Unable to build default ASP.Net Core Web Application (.NET Core) on Visual Studio Team Services using Hosted Agent

Question

Having created a new ASP.Net Core Web Application (.Net Core) project in Visual Studio 2015 Update 3 and checked this in to a Visual Studio Team Services git repository. I am using the release version of .Net Core and ASP.Net Core.

I am now trying to build this using the VSTS Build system using a build definition based on this guide: https://www.visualstudio.com/en-us/docs/build/apps/aspnet/aspnetcore-to-azure

However, the build fails on the dotnet restore step with the log shown below (first part not included, this is from where it starts to fail).

What am I doing wrong? Do I need to prep the current Hosted Agents in any way to get this working with the v1.0.0 release of ASP.Net Core?

Answer 1

Replace the "tools" in the project.json this way:

 "tools": {

    "BundlerMinifier.Core": "2.1.258",

    "Microsoft.AspNetCore.Razor.Tools": {

      "version": "1.0.0-preview2-final",

      "imports": [

        "netstandard1.6"

      ]

    },

    "Microsoft.AspNetCore.Server.IISIntegration.Tools": {

      "version": "1.0.0-preview2-final",

      "imports": [

        "netstandard1.6"

      ]

    },

    "Microsoft.EntityFrameworkCore.Tools": {

      "version": "1.0.0-preview2-final",

      "imports": [

        "netstandard1.6"

      ]

    },

    "Microsoft.Extensions.SecretManager.Tools": "1.0.0-preview2-final",

    "Microsoft.VisualStudio.Web.CodeGeneration.Tools": {

      "version": "1.0.0-preview2-final",

      "imports": [

        "portable-net45+win8+wp8+wpa81",

        "netstandard1.6"

      ]

    }

  }

Microsoft.VisualStudio.Web.CodeGeneration.Tools needs to import the netstandard1.6 and portable-net45+win8+wp8+wpa81
