How to install Microsoft.NET.Native.Runtime.2.1-rel package while sideloading an app in Microsoft Store

I am trying to sideload an app using visual studio 2017. Steps I am taking:

Right Click on the project->Store->Create app packages-> for sideloading....

It does create the package.

However when i try to install the packagebundle, i have this error

App Installer failed to install package dependencies. Ask the developer for Microsoft.NET.Native.Runtime.2.1-rel package.

When i take a look at Dependencies/x86/ i have 3 packages. There is Microsoft.NET.Native.Runtime.2.1 but not Microsoft.NET.Native.Runtime.2.1-rel

I found this but downgrading UWP didnt help. Anybody has an idea how to fix this?

EDIT: After trying to downgrade uwp to an ever lower version as suggested in a comment (6.0.1) I got this other error:

Failure reason: Windows cannot install package because this package depends on a framework that could not be found. Provide the framework "Microsoft.NET.Native.Framework.2.0" published by "CN=Microsoft Corporation, O=Microsoft Corporation, L=Redmond, S=Washington, C=US", with neutral or x86 processor architecture and minimum version 2.0.25709.0, along with this package to install. The frameworks with name "Microsoft.NET.Native.Framework.2.0" currently installed are: {} Failure text: Package failed updates, dependency or conflict validation. (0x80073cf3)

After I downgraded, it works when I install in a pc, but not in Hololens where it shows this error. (I build for x86 architecture)

UPDATE: I have accepted an answer, because it pointed me in the right direction, however the latest stable version didnt work for me. I downgraded to an even lower version. I dont know why, but it seemed to fix the issue.

I had the same problem. Later I have noticed that I have installed "Pre-release" version of "Microsoft.NETCore.UniversalWindowsPlatform" Nuget. Downgraded to latest stable version solved my problem.
