Cannot detect .NET Core. Please install .NET Core SDK and restart Rider.


As the title says, when I want to create a new .net core project the templates give this error message.

Running MacOS Mojave 10.14.5

Dotnet version 3.0.100

.NET Core SDK is installed and dotnet executable is at /usr/local/share/dotnet/dotnet which is also what is configured under Toolset and build > .NET Core CLI executable path

What am I missing here? Editing existing projects works fine.


Hi there!
I was facing the exact same problem. And somehow, any attempt to fix it was failing.
But I've remembered that I have installed RIDER from POP!_SHOP (it's a clone of Ubuntu's Snap store).

So, I've removed it and installed using the toolbox app. Everthing is working fine now. I hope it may be helpful to you.


Hello Gustav,

The issue reminds the following well-known one: RIDER-31552. Could you please let me know what is your Rider version and if it is not the latest one, try installing it?


This is still true in May 2021. Do not install the snap store version. It's broken.


Hello James, could you open Configure | Preferences | Preferences | Build, Execution, Deployment | Toolset and Build -> .NET Core CLI executable path and check that there is the right path?
