Issue with resolving Dotnet in Rider

Problem

Dotnet in Rider: cannot resolve symbol 'Microsoft'

Solution

Please go to the setting > build, Execution, Deployment > Toolset and Build and then you can see like this.

After that, you have to change use MSBuild version the default MSBuild version might be Auto detected (##) .... then click the combo box and please select a version that supports you.

The 4.0 is batter in my case. after select and apply them, you can see a success message from Rider. otherwise, Rider shows an error. if you have an error please try another option. thanks.
