How to setup Rider on Mac OS, Mojave?

Question

Microsoft.Common.CurrentVersion.targets(1195, 5): [MSB3644] The reference assemblies for framework ".NETFramework,Version=v4.7.2" were not found. To resolve this, install the SDK or Targeting Pack for this framework version or retarget your application to a version of the framework for which you have the SDK or Targeting Pack installed. Note that assemblies will be resolved from the Global Assembly Cache (GAC) and will be used in place of reference assemblies. Therefore your assembly may not be correctly targeted for the framework you intend.

8:09 PM .NET Framework is not found: MsBuild can not find TargetFramework assemblies, specify a Mono MSBuild in settings. You can download the latest stable Mono release.

I am trying to set up both Visual Studio and Rider on Macbook running Mojave. I am running into this problem where I have to call for mono building location. I have installed the latest stable Mono but I don't know the location I have to add.

If someone has a video or online document explaining how to install .Net framework on mac, that would be helpful.

Here is the additional image to the issue on Rider in Mojave

Answer 1

Usually Rider automatically detects all installed mono runtimes and take a right one:

But you can specify your own runtime by selecting 'Custom' in the 'Mono executable path' combo box =)

Answer 2

Mono on macOS installs into the library "Frameworks", so the base directory of the install ends up being:

/Library/Frameworks/Mono.framework/

Note : I am not sure it is looking for this base dir or one of its subs:

├── Commands -> /Library/Frameworks/Mono.framework/Versions/Current/bin
├── External
├── Headers -> /Library/Frameworks/Mono.framework/Versions/Current/include
├── Home -> /Library/Frameworks/Mono.framework/Versions/Current/
├── Libraries -> /Library/Frameworks/Mono.framework/Versions/Current/lib
├── Mono -> /Library/Frameworks/Mono.framework/Versions/Current/lib/libmono-2.0.dylib
└── Versions
