Dotnet Core 2.0.X on Rasbian Stretch running on Raspberry Pi 3 Kit - Unable to run compiled app

• I have followed all instructions from here: https://goo.gl/D1hec7,
• Used https://dotnetcli.blob.core.windows.net/dotnet/Runtime/master/dotnet-runtime-latest-linux-arm.tar.gz pack for Rasbian stretch OS on Raspberry pi 3.
• Receiving following error when I tried to run simple "hello world" program that is created on Windows machine with CLI command (dotnet new console)

That means that it can't find the 2.0.0 runtime next to where dotnet is. Where did you extract the tar.gz and if you run which dotnet where is it running from?

[pavangayakwad]

I extracted it to /opt/dotnet folder and created symbolic link in /usr/local/bin.

When I run for dotnet --version, it is showing me the same error

[Petermarcu]

under /opt/dotnet do you have /opt/dotnet/host/fxr with some versions as well as /opt/dotnet/shared/Microsoft.NETCore.App/2.0.0 or higher? I'm guessing you have 2.1 there.

I believe whats happening is that you are downloading from master which is 2.1. Either update your project to be netcoreapp2.1 or download the tar.gz from here to get the latest 2.0 runtime:

https://dotnetcli.blob.core.windows.net/dotnet/Runtime/release/2.0.0/dotnet-runtime-latest-linux-arm.tar.gz

ok, tried this as well. but no luck same error.

My project targets 2.0 and if I run it against download 2.1 run-time, ideally it should run without any problem. wouldn't it?

[Petermarcu]

We're working on making it an option to run a 2.0 app on 2.1 but it doesn't work today. 2.1 is really early still. You should have no problem running once you install 2.0. Can you share the list of folder under dotnet/shared/Microsoft.Netcore.App? Is 2.0.0 there or 2.0.something...

[pavangayakwad]

Ok, after following instructions from here https://github.com/dotnet/core/blob/master/samples/RaspberryPiInstructions.md, I was able to run the app.

oh man! It took 2 days for me to figure out all these. anyway, wondering, why not include all these in the first place?

[Petermarcu]

Glad its working. Those instructions are aimed at making it easier because its a self contained app. Why not include all of what?

[Petermarcu]

Going to close this now. If there is something more we can do in the instructions, let us know.
