FSlex/FSyacc crash - can't locate FSharp.Core assembly

Question

I'm having an issue with FSlex/FSyacc crashing on my machine.

In context this is inside Visual Studio 11 beta running on Windows 8 Consumer Preview (32 bit) running inside a Parallels virtual machine.

------ Build started: Project: Basis, Configuration: Debug Any CPU ------ C:\Windows\Microsoft.NET\Framework\v4.0.30319\Microsoft.Common.targets(1546,5): warning MSB3245: Could not resolve this reference. Could not locate the assembly "log4net, Version=1.2.11.0, Culture=neutral, PublicKeyToken=669e0ddf0bb1aa2a". Check to make sure the assembly exists on disk. If this reference is required by your code, you may get compilation errors.

Done building project "Syntax.fsproj" -- FAILED.

The relevant piece seems to be this:

Unhandled Exception: System.IO.FileNotFoundException: Could not load file or assembly 'FSharp.Core, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a' or one of its dependencies.

at .$FSharp.PowerPack.FsYacc.Driver.main@()

Not sure why it can't locate the FSharp.Core assembly.

Ideas?

Answer 1

I had forgotten to install F# 2.0. There was a dependency on that.
