Error while installing .NET Core Debugger on OSX - macos

Question

I've installed the latest version of Visual Studio Code (1.1.1) in OSX El Capitan (10.11.4). I also installed the latest version of Core RC2. dotnet --version gives me 1.0.0-preview1-002702. One of the web threads I read said to delete the older version of OmniSharp and install the latest, which I did. I also installed OpenSSL via Brew.
When I installed the newest yo generator for aspnet and created a sample app, it runs fine. When I try to open that folder in Visual Studio Code, I get this in the Output window:

I tried to do both steps 1 & 2, but I still get the same error. My project.json file looks like this:
{

If I try to run debug in VS Code using the .NET Core Launch (web), I get an error:
Debug adapter executable
'/Users/rheckart/.vscode/extensions/ms-vscode.csharp-0.3.7/coreclr-debug/debugAdapters/OpenDebugAD7'
not found.
Any ideas as to why this isn't working?

Answer 1

I received the same error. For me, I noticed there was an update available for the VS Code C# extension (I saw the green circle on the icon in the lower-left). Once I installed the update (version 1.0.10) and restarted VS Code, the error went away and I got "Successfully installed .NET Core Debugger".

Answer 2

I managed to resolve this by removing an older .NET Core version and installing the latest one. It appears the installation failed due to command line options the older version did not support.
Uninstall script and latest installation package can be found here (steps 1 and 2): https://www.microsoft.com/net/core#macosx
