I had used VS CODE before. But now I would like to try JetBrains Rider. Currently, I have only NetCore 3.0. But before I had 2.2. I had removed old NetCore and installed new one. I am trying to create new project. But Rider don't see NetCore 3.0.

error

I did not see ability to change NetCore SDK. My operation system is Linux Mint 18. I have only one NetCore version. And it's 3.0.

error

Why it's happening?

Which dotnet executable path was detected by Rider in "File | Settings | Build, Execution, Deployment | Toolset and Build" (["Configure" dropdown ->Settings] on the Welcome screen)? Please, attach a screenshot to the issue youtrack.jetbrains.com/issue/RIDER-28207. Also, you can try to set a custom path to dotnet.exe in these settings. Please, clarify how did you installed dotnet to the home folder. Was it some default installation configuration? - sbyzova

It is pretty common problem. I have solved it by specifying path to .Net Sdk manually. This is the screen of settings:

  1. Specify path to .NET binary file. It is usually has the following path /home/<your_user>/dotnet/dotnet

  2. Specify path to MSBuild file. For example my path is the next : /home/aleksej/dotnet/sdk/3.0.100-preview6-012264/MSBuild.dll

  3. Save

  4. Profit!

P.S. My operation system is Linux Mint 19.1. And version of .Net Core is not important in this case.

Update

I forgot about one important moment. If you need to change .NET version for your solution, you have to place special global.json file in the root of your solution. If you are changing .NET version for a project - put global.json on the project root path.

Example of global.json for changing .NET version:

{
  "sdk": {
    "version": "2.2.300"
  }
}

If you want to find the location of your sdk then write the following command: dotnet --list-sdks. It has to show you 3.1.403 [/usr/share/dotnet/sdk] or similar to it. If it's not then consider it installed using the following guide Install .NET Core on Linux . Then select the dotnet file in .NET CORE CLI executable path, with it's respective MSBuild.dll . enter image description here
PD: Remember to save the changes globally!!!.
