Building aspnet core sources from github on windows 10 with VS2017

I want to delve deeper into the asp.net core sources which are hosted over at gihub.

So take the asp.net core security which can be found here - https://github.com/aspnet/Security.

I've downloaded and installed the GitHub desktop. I've cloned the repo locally on my machine. I'm looking at the dev branch:

Git dev

I have downloaded and installed the SDK from https://www.microsoft.com/net/core/preview#windowscmd which I think the projects target (I might be wrong), but here is the authentication.csproj:

<Project Sdk="Microsoft.NET.Sdk">

  <Import Project="..\..\build\common.props" />

  <PropertyGroup>
    <Description>ASP.NET Core common types used by the various authentication middleware components.</Description>
    <TargetFramework>netstandard2.0</TargetFramework>
    <NoWarn>$(NoWarn);CS1591</NoWarn>
    <GenerateDocumentationFile>true</GenerateDocumentationFile>
    <PackageTags>aspnetcore;authentication;security</PackageTags>
    <EnableApiCheck>false</EnableApiCheck>
  </PropertyGroup>

  <ItemGroup>
    <PackageReference Include="Microsoft.AspNetCore.Authentication.Core" Version="$(AspNetCoreVersion)" />
    <PackageReference Include="Microsoft.AspNetCore.DataProtection" Version="$(AspNetCoreVersion)" />
    <PackageReference Include="Microsoft.AspNetCore.Http" Version="$(AspNetCoreVersion)" />

  </ItemGroup>

</Project>

There is a solution file (Security.sln) and a build.cmd, build.ps1, build.sh. I was hoping to load the solution and compile, but things never seem that straight forward anymore.

Having ran build.ps1 which seemed to install a few things, then build.cmd which seemed to execute, I've loaded the solution in VS2017. I just cannot get anything to build.

The error window is currently going crazy with a set of errors which seems to be stuck in a loop going up from 10 to 88, then back to 10 in an endless loop.

I cannot find any info anywhere on building these solutions. Can anyone give me a heads up on what is needed to build them? Its late, it has been a long day, and my eyes hurt.

Here is a selection of the errors/warnings:

Solution

  • Question is a bit dated now. I am writing this with posterity in mind.

    Description:

    I ended up with a similar pile of error messages after:

    -Being notified that a particular development project got updated to .NET Core 2.0

    -Downloading and installing .NET Core 2.0

    -Merging the updated branch

    -Doing a clean build

    Solution:

    I checked the project properties and realized that .NET Core 2.0 installation did not appear in "Target Framework" drop down.

    The problem went away after I updated VS2017 to latest available patch. After which .NET Core 2.0 was available as a target framework.
