Azure Service Fabric unable to do CI on VSTS with ASP.NET Core

Question

I have Service Fabric based system created and working on production environment (and development). Everything is ok. Now I was trying to setup CI on Visual Studio Team Services with provided templates for ASF projects. Unfortunately my system has Actors (.NET 4.5.2) and WebAPI based on ASP.NET Core 1.1. I have references to Actor interfaces project (also .NET 4.5.2) forom .NET Core.

When I'm trying to build project with default template I'm recieving error because dotnet restore was not run. Ok, so I've added step to run dotnet restore but then I'm getting error complaining that it cannot find reference to Actor.Interfaces.

dotnet restore also fails on my dev machine but solution build with VS goes ok.

How can I fix this issue?

[UPDATE]

Thanks Mardoxx, I've made some progress... now I'm getting below error for *.sln buld. My solution is VS2015 (set in build task), I've set env to Hosted VS2017.

[UPDATE2]

After taking steps presented by starain-MSFT I'm getting errors during 'dotnet restore':

log  : Restoring packages for d:\a\1\s\AdminPanel\project.json...

[UPDATE3]

Another update after @starain input.

Now I'm getting error that references (to .NET 4.5.2 projcects from Core projects) could not be found.

Answer 1

Refer to these steps below:

1. Create a new build definition with Azure Service Fabric Application template
2. Change Visual Studio Version to Visual Studio 2015 for Visual Studio Build steps.
3. Select NuGet Installer step/task, change NuGet version to 3.5.0 in Advanced section.
4. Select Options tab and change Default agent queue to Hosted
5. Queue build with Hosted agent. (Not Hosted VS 2017)

All build steps:

1. NuGet Installer (NuGet restore ***.sln)
2. .Net Core (dotnet restore)
3. Visual Studio Build (Build solution ***.sln)
4. Visual Studio Build (Build solution ***.sfproj)
5. Copy Files
6. Delete files
7. Update Service Fabric App Versions
8. Copy Files
9. Publish Build Artifacts
