How to set DOTNET_REFERENCE_ASSEMBLIES_PATH?

Question

I am having a few issues at the moment building my application. I can run dotnet restore, but once I run dotnet build or run it mentions:-

The current project is not valid because of the following errors:- dir/project.json(35, 15): error DOTNET1012: The reference assemblies directory was not specified. You can set the location using the DOTNET_REFERENCE_ASSEMBLIES_PATH environment variable.

Does anybody know how to set this or have they seen this issues before?

Thanks in advance!

Because you use .net framework 4.5.2 on Linux, so you will need to install Mono first, and then set the DOTNET_REFERENCE_ASSEMBLIES_PATH environment variable to /usr/lib/mono/xbuild-frameworks.
