Namespace not defined

[ghost]

With only VS 2017 installed and only F# 4.1 installed.
System: Windows 10 1703
ionide: 2.25.9

It's unable to resolve namespace. Simple step to reproduce is just to create a expecto project from template in vs code.

Some log here:

System.IO.FileNotFoundException: Could not load file or assembly 'Microsoft.Build.Utilities.v12.0, Version=12.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a' or one of its dependencies. The system cannot find the file specified.\r\nFile name: 'Microsoft.Build.Utilities.v12.0, Version=12.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a'\r\n   at Microsoft.FSharp.Compiler.SourceCodeServices.ProjectCrackerTool.ProjectCrackerTool.FSharpProjectFileInfo..ctor(String fsprojFileName, FSharpOption`1 properties, FSharpOption`1 enableLogging)\r\n   at Microsoft.FSharp.Compiler.SourceCodeServices.ProjectCrackerTool.ProjectCrackerTool.getOptions@387(Boolean enableLogging, FSharpList`1 properties, String file)\r\n   at Microsoft.FSharp.Compiler.SourceCodeServices.ProjectCrackerTool.ProjectCrackerTool.getOptions(String file, Boolean enableLogging, FSharpList`1 properties)

Seems like FSAC looking for msbuild12?

We don't yet support VS2017 only installation, requirements for the plugin are listed in readme.
