Roslyn: Microsoft.CSharp.Core.targets(59,5): error on linux.

[NMSAzulX]

I used travis-ci to build project.
Here is the build configuration:

language: csharp
solution: Natasha.sln
mono: none
dotnet: 2.2
dist: xenial
sudo: required

before_install:
  - sudo apt-get install nuget

env:
  global:
    - DOTNET_SKIP_FIRST_TIME_EXPERIENCE: true
    - DOTNET_CLI_TELEMETRY_OPTOUT: 1

install:
  - dotnet restore

script:
  - dotnet build -c Release

Here is the error message: build--log
You can turn to the bottom few lines.

How can I solve this problem?

[jmarolf]

This looks to be a mono bug? which version of mono are you using?

@jmarolf

I used commnad : "mono: none". But I found the log:

@jmarolf "error MSB3883: Unexpected exception: " is an old error. But how to sove it? It should be an environmental problem, but I don't know what's missing.

Same problem as https://github.com/dotnet/roslyn/issues/36705, Microsoft.Net.Compilers is a Windows-only package. Closing as duplicate

[jcouv]

Ah, good catch. Thanks
@NMSAzulX I think the recommendation is to use the Microsoft.Net.Compilers.Toolset package instead (that one is cross-platform, if I understand properly).

@jcouv @agocke Thank you~
