Make projects .NET 4.5-compatible about core HOT 3 CLOSED

The issue is that .NET 4.5 beta has F# core library FSharp.Core versioned 4.3.0.0 (F# 3.0) and .NET 4.0 has FSharp.Core 4.0.0.0. To make sure all F#-dependent code works together in an ASP.NET project, the Web.config must include binding redirects that make the runtime converge on a single version of FSharp.Core.

Unfortunately I have not found a way to make a versatile Web.config that would work in all environments: targeting .NET 4.0 without F# 3.0 installed, targeting .NET 4.5 without F# 2.0 installed, and combinations.

I am currently experimenting with different assembly binding redirects trying to find a common denominator.

In the meanwhile the workaround is very simple:

• If you are building for .NET 4.0 and using F# 2.0 stick to the defaults;
• If you want to use WebSharper with F# 3.0 and build for .NET 4.5, edit Web.config and set redirects to the following:

{{{
#!xml














}}}

The latest code resolves the problem by making VS 2011 templates use .NET 4.5 by default and VS 2010 templates use .NET 3.5. In addition, at install time we detect if FSharp.Core 4.3.0.0 is present or not, and if yes, use that as the default redirect in all executable configuration files such as WebSharper.exe.config, if not, fall back to 4.0.0.0.
