Roslyn – CodeAnalysis.MsBuild – How to open project?

I’m trying to generate a file containing metadata about the analyzed code, given a csproj. I’m failing at step #1, opening the project.

public static async Task Main(string[] args) {     MSBuildLocator.RegisterDefaults();     using (var workspace = MSBuildWorkspace.Create())     {         workspace.WorkspaceFailed += (_, failure) => Console.WriteLine(failure.Diagnostic);          var project = await workspace.OpenProjectAsync(args[0]);     } } 

Analyzer project file:

<Project Sdk="Microsoft.NET.Sdk">    <PropertyGroup>     <TargetFramework>netcoreapp2.1</TargetFramework>     <ApplicationIcon />     <OutputType>Exe</OutputType>     <StartupObject />     <LangVersion>latest</LangVersion>   </PropertyGroup>    <ItemGroup>     <PackageReference Include="Markdig" Version="0.20.0" />     <PackageReference Include="Microsoft.Build.Locator" Version="1.2.6" />     <PackageReference Include="Microsoft.CodeAnalysis" Version="3.4.0" />     <PackageReference Include="Microsoft.CodeAnalysis.Workspaces.MSBuild" Version="3.4.0" />     <PackageReference Include="System.Configuration.ConfigurationManager" Version="4.7.0" />   </ItemGroup> </Project> 

This outputs

The project I’m trying to open is really simple, the default class library template:

<Project Sdk="Microsoft.NET.Sdk">    <PropertyGroup>     <TargetFramework>netcoreapp2.1</TargetFramework>   </PropertyGroup>  </Project> 

namespace SimplestAssembly {     public class Class1     {     } }
