Access wcf from netcoreapp2.0 - asp.net-core

I have a asp dotnet core 2.0 project that needs to talk to a downstream WCF service
The proj file is targeting netcoreapp2.0
I have added nuget packages for System.ServiceModel.Primitives and have almost everything I need apart from something in the System.ServiceModel.Configuration namespace which doesnt appear to be available on Nuget
In the past, I have successfully talked to the WCF service in a netcore1.1 project (by making it target net461)
However, this doesnt appear to be an option if you want to take advantage of netCore2.0 functionality. If you target net461 then you cant access netcore2.0 features
Should this be possible?
Am I doing something wrong?
Can you target net461 and also use netcore2.0 features?
or is there a way I can target netcoreapp2.0 and still access System.ServiceModel.Configuration?
Or do I need to target netcoreapp2.0 and do something else that allows me to access System.ServiceModel.Configuration?
thanks

If you use at least VS 2017 version 15.5, you can add the WCF service as a connected service. The wizard will add the required packages and generate the client code. (in previous VS 2017 versions, you'd need a preview extension).
You can access this wizard from the "Add Connected Service" context menu item:

Is it possible to create custom GraphServiceClient in UiPath? (and how)

We are needing additional Office 365 functionality that is not provided by the standard Office 365 package by UiPath (such as marking emails as read/not read, changing the subject lines of emails already in a shared mailbox, etc).
Having looked through Microsoft documentation, it should be possible via code - but this doesn't seem to work in UiPath.
https://learn.microsoft.com/en-us/graph/sdks/choose-authentication-providers?tabs=CS
UiPath moans that it needs netstandard version 2.0.0.0 to create a new GraphServiceClient - however, I don't think that I'm able to add that assembly to the project.
Does anyone know how we can create the custom graph connection in UiPath?
As I don't want to copy the doc page, all you need is written on Github (Microsoft Graph .NET Client Library).
The Microsoft Graph .NET Client Library targets .NetStandard 2.0 and
.Net Framework 4.6.2.
To install the client library via NuGet:
Search for Microsoft.Graph in the NuGet Library, or
Type Install-Package Microsoft.Graph into the Package Manager Console.
For UiPath setup, use your link. Should work in the Invoke code block.

fully compatible powerbi.api package with aspnetcore?

i was able to get the sample asp.net embedded powerbi to work with my reports
now i have to migrate it aspnetcore
i was hopeful when i saw this post - seeing that someone was able to get it done
Embed Power BI Report In ASP.Net Core Website
so i:
started a new project with the aspnetcore
installed the powerbi package
now when compiling im getting this warning:
Package 'Microsoft.PowerBI.Api 2.0.11' was restored using '.NETFramework,Version=v4.6.1' instead of the project target framework '.NETCoreApp,Version=v2.0'. This package may not be fully compatible with your project.
i searched and couldnt find a powerbi package that was specific to aspnetcore
is there one? will there be a conflict crossing cores? or does it not matter?
UPDATE:
4.6.1 powerbi package does indeed work with aspnetcore 2
but looking forward to a powerbi package specifically coded for core
As you can see this is just a warning, not an error. That warning appears because .NET Core 2.0 applications can use some Nuget packages which target .NET Framework 4.6.1 (or less). However, this inclusion might fail if the referenced .NET 4.x package contains some API not included into .NET Core/.NET Standard 2.0
So, my advice - try to run your application. If it works well at the first glance - then, most probably that PowerBI package does not contain any not supported APIs and will work well further. If it fails right at start - then you will need to wait for the release of the new version of that package which targets .NET Standard 2.0.

Reference third-party class libraries

I am working with .Net Core 1.0 (running under the .Net Framework 4.6.1, non-portable).
I need to include some DLLs that are from a locally-built GitHub project. When I build those projects, and then attempt to "Add Reference" to the resulting DLLs, I get a message saying I can't add them to a Core project directly.
After more research, I found a lot of information regarding "private" NuGet packages. However, those seem overly complex / overly engineered.
Is there any way I can do the following:
Without having to go through the headache of creating a private NuGet repository, can I just "add reference" to the built assemblies that are sitting in the bin folder of the NuGet projects I pulled?
I really don't want to have to build a local-only NuGet package. Mostly because I've already wasted too much time on this issue, and because I read this entire concept is about to be scrapped and turned into something else (sounds familiar by now)... such as the Roslyn-based build system on GitHub.
My current state:
Visual Studio Professional 2015
.Net Core 1.0.1
.Net Core 1.0.1 Tooling Preview 2
No, as for now you have to create a nuget package before and restore it via Nuget. You can use a simple folder as NuGet source, so if you put your compiled NuGet package in C:\packages, you can add this as a source to NuGet (while in the NuGet UI, click the settings Icon and add the folder as new source).
This may change with the next release of ASP.NET Core (1.1), as the .NET/ASP.NET Core team is working to move from *.xproj to *.csproj files.
One of the reasons why you need to use nuget is because it can contain multiple targets and project.json allows you to target multiple platforms (i.e. net452 and netcoreapp1.0).

Understanding ASP.NET Core Dependencies and Capabilities

When I use a Visual Studio 2015 template to create a brand-new ASP.NET Core project, I see a couple of unexpected pieces. I'd like to understand these:
By default, the new project targets dnxcore50 and dnx451. I thought ASP.NET 5 / MVC 6 required .net 4.6, so I don't know why dnx451 is one of the default targets.
Regardless of dnx target, the startup.cs file specifies app.UseIISPlatformHandler. I've been running the dnxcore50 target in Docker (i.e. Linux) without any problem, even though Linux does not have IIS. So I don't know what UseIISPlatformHandler does. I can find no documentation for it either.
Can anyone clarify?
Why dnx451 instead of dnx46 is basically IIS's fault, see answer here. Also perhaps the templates run behind because Azure has not yet switched to 4.6? Just a little theory of mine. I'm not sure.
UseIISPatformHandler is again only used for IIS. You can savely remove it if you have no interest in publishing your web app to IIS. You can learn more about the HTTP Platform Handler (which IIS needs) here. And you can learn more about the IIS Platform Handler Middleware from the source code.
Does this make it more clear?

Building C++ projects that targets framework 3.5 but produces assemblies targeting framework 4.0

Background
We have a C++ solution that has been moved from VS2005 to VS2010 where the project files were targeting the .net framework 3.5 but since moving over to VS2010, all of the project files were showing that they were targeting the.net framework 4.0. I have since changed the .vcxproj files manually so that they are targeting the .net framework 3.5, using the method described in the Community Content on this link
The Problem
When I build these project files, manually or via an automated build, the output assemblies are still targeting the .net framework 4.0. I can tell this by using various methods described here. I also know that this is the case as I build and run the installer for this application. Once the application has been installed (which then shows as a service), I try to start the service on the target machine. This service will not start on a machine without the .net framework 4.0 installed. If 4.0 is then installed, the service will start, so this is another test that I can run that shows me that the application has a dependency on .net framework 4.0 which it should not.
The Aim
Ideally, I need to build this application so that the outputs are targeting the .net framework 3.5 instead of 4.0 so that it will actually run as it is supposed to! I have tried to use the 3.5 version of MSBuild as described in one of the answers given for this question here but got the same error that is described underneath that post.
Can anyone help with this? It's proving to be a right pain and I've been banging my head against the wall for over a week trying to get this sorted!
Thanks again in advance
Make sure you follow all the instructions as provided in the first link you posted.
For example,
Make sure you have Visual Studio 2008 installed on the build server.
Make sure you also change each project's "Platform Toolset" to v90.
Verify the project's framework version: "In Solution Explorer, right-click your project and then click Properties. In the Property Pages window, in the left pane, expand Common Properties and then select Framework and References. Verify that the new Framework version appears at the top of the right pane."
