Resolving MSBuild 4.0 Warnings
I have updated the solution to use MSBuild 4.0. It compiles, but I get a lot of warnings like:
"T: \ projects \ Castle.Core \ buildscripts \ Build.proj" (Package target) (1) -> "T: \ projects \ Castle.Core \ Castle.Core-vs2008.sln" (Build target) (2: 2) -> "T: \ projects \ Castle.Core \ src \ Castle.DynamicProxy.Tests \ Castle.DynamicProxy.Tests-vs2008.csproj" (default target) (3: 2) -> D: \ Windows \ Microsoft.NET \ Framework \ v4.0.30319 \ Microsoft.Common.targets (847.9): warning MSB3644: The reference assemblies for framework ".NETFramework, Version = v4.0.30319" were not found. To resolve this, install the SDK or Targeting Pack for this framework version or retarget your application to a version of the framework for which you have the SDK or Targeting Pack installed. Note that assemblies will be resolved from the Global Assembly Cache (GAC) and will be used in place of reference assemblies. Therefore your assembly may not be correctly targeted for the framework you intend. [T: \ projects \ Castle.Core \ src \ Castle.DynamicProxy.Tests \ Castle.DynamicProxy.Tests-vs2008.csproj]
How can I fix these warnings? This is related to the .NET 4.0 multitasking package or SDK, but there is no SDK for .NET 4.0. AFAIK and Multi-Target pack cannot be installed separately.
Any ideas would be appreciated.

Have you tried looking at the result of the ResolveAssemblyReferences task in MSBuild with level diagnostics enabled ('/ v: diag'). This should tell you which directories the build process is looking for to find the DLL. Although, if the build process can't find it, I am very surprised that the IDE doesn't show an issue with this link in the project.
There is .Net Framework SDK, but also part of Windows SDK. The version shipped with VS2010 is 7.0A and the latest is 7.1. There may be a path / link conflict that was introduced by the installers if you installed one or both separately.
