Rider doesn't see NetCore 3.0

Question

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.

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.

Why it's happening?

Answer 1

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"
  }
}
