What versions of WebSharper and WebSharper.Suave do you have referenced?

Also, are you running from within an IDE? If so, there might be issues with the IDE still referencing an old WebSharper.MSBuild.dll, so you should try closing it and reopening it.

Restarting VS has not helped.

packages.config with which everything compiled and works OK:

Paket pin WebSharper.Suave to version 3.4.8.11, but initially it was 3.6.1.22. Hmm.

vasily-kirichenko commented 8 years ago

After I pin the right version to WebSharper.Suave, paket.lock for it looks like this:

WebSharper.Suave (3.6.1.22)
      Mono.Cecil (>= 0.9.6.1)
      Suave (>= 0.33.0)
      WebSharper (>= 3.6.2.220)
      WebSharper.Owin (>= 3.6.1.115)

Now the project compiles, but crashes on startup:

Unhandled Exception: System.MissingMethodException: Method not found: 'Microsoft.FSharp.Core.FSharpFunc2<HttpContext,Microsoft.FSharp.Control.FSharpAsync1<Microsoft.FSharp.Core.FSharpOption1<HttpContext>>> WebSharper.Suave.WebSharperAdapter.ToWebPart(WebSharper.Sitelets.Sitelet1<!!0>, Microsoft.FSharp.Core.FSharpOption1<System.String>, Microsoft.FSharp.Core.FSharpOption1)'. at <StartupCode$Monitor-Web>.$Main.main@()

vasily-kirichenko commented 8 years ago

Solved it. It's necessary to reference FSharp.Core package and delete old static ref on FSharp.Core.dll from project file. paket install adds the following:

<Choose>
    <When Condition="$(TargetFrameworkIdentifier) == '.NETFramework' And ($(TargetFrameworkVersion) == 'v4.5' Or $(TargetFrameworkVersion) == 'v4.5.1' Or $(TargetFrameworkVersion) == 'v4.5.2' Or $(TargetFrameworkVersion) == 'v4.6')">
      <ItemGroup>
        <Reference Include="FSharp.Core">
          <HintPath>..\..\packages\FSharp.Core\lib\net40\FSharp.Core.dll</HintPath>
          <Private>True</Private>
          <Paket>True</Paket>
        </Reference>
      </ItemGroup>
    </When>
  </Choose>
  <Choose>

And you must find and delete this:

 <TargetFSharpCoreVersion>4.3.1.0</TargetFSharpCoreVersion>

and this:

<Reference Include="FSharp.Core, Version=$(TargetFSharpCoreVersion), Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a">
      <Private>True</Private>
</Reference>
