Argument Exception when trying to run dnu restore

[ganeshran]

Hi I am trying to run the demo Hello World program on Centos7 but getting the error. It isn't able to install the dependencies.

⇒ dnu install System.Console
Microsoft .NET Development Utility CoreCLR-x64-1.0.0-beta7-12264

I have tried this on Ubuntu 14.04 with the same result. Also changed the endpoint to http:// instead of https. No luck

Restoring packages isn't supported on the CoreCLR-based DNX yet. You need to switch to the Mono-based DNX, restore there, switch back to CoreCLR and then run. See https://github.com/dotnet/coreclr/blob/master/Documentation/install/get-dotnetcore-dnx-linux.md#run-your-app

Hi @akoeplinger thanks for your reply. I tried switching to mono but am getting another error. I had switched to coreclr because dnu restore wasn't working on mono first.

I also tried to remove all runtimes and start from scratch. still no go :(

Which Mono version (mono --version) are you using?

[ganeshran]

@akoeplinger Found the issue. I had installed mono-core package from epel repo. That doesn't work with dnu. After removing it and adding mono repo to yum and installing mono-complete it's working fine.

Thanks! I am able to run the code now

[ganeshran]

Please close the issue. Appreciate the support!
