Visual Studio F# error - FSharp.Core.sigdata -

-

i've installed latest fsharp bundle, whenever hit control-spacebar in visual studio, error:

problem reading assembly 'fsharp.core, version=4.3.1.0, culture=neutral, publickeytoken=b03f5f7f11d50a3a': error opening binary file 'c:\windows\microsoft.net\assembly\gac_msil\fsharp.core\v4.0_4.3.1.0__b03f5f7f11d50a3a\fsharp.core.dll': fsharp.core.sigdata not found alongside fsharp.core

also, when try compile, following errors:

fsc: error fs1223: fsharp.core.sigdata not found alongside fsharp.core

fsc: error fs0229: error opening binary file 'c:\windows\microsoft.net\assembly\gac_msil\fsharp.core\v4.0_4.3.1.0__b03f5f7f11d50a3a\fsharp.core.dll': fsharp.core.sigdata not found alongside fsharp.core

on top of that, following errors when try run fsi.exe:

> session termination detected. press enter restart.    unknown(1,1): error fs1223: fsharp.core.sigdata not found alongside fsharp.core   unknown(1,1): error fs0229: error opening binary file 'c:\windows\microsoft.net\assembly\gac_msil\fsharp.core\v4.0_4.3.1.0__b03f5f7f11d50a3a\fsharp.core.dll': exception of type 'microsoft.fsharp.compiler.errorlogger+stopprocessing' thrown.   unknown(1,1): error fs3160: problem reading assembly 'fsharp.core, version=4.3.1.0, culture=neutral, publickeytoken=b03f5f7f11d50a3a': exception of type 'microsoft.fsharp.compiler.errorlogger+stopprocessing' thrown.

note: can still run fsi.exe f# 3.0. i'm having issue 3.1 (c:\program files (x86)\microsoft sdks\f#\3.1\framework\v4.0)

any idea how can functioning f#?

edit 3

it appears again able compile f# projects after numerous repair installs/system reboots of things. issues fsi.exe , visual studio intellisense remain.
