Mimicking the build resolution of the msbuild process

I am writing a validation tool that checks the versions of files referenced by a project. I want to use the same resolution process as MSBuild.

For example, Assembly.Load (..) requires the fully qualified name of the assembly. However, in the project file we can only have something like "System.Xml". MSBuild probably uses the version of the target project target structure and some other heuristics to decide which version of System.Xml to load.

How could you redo (or directly use) the msbuild build process?

In other words, at runtime, I want to take the line "System.Xml" along with the other information in the .csproj file and find the same file as msbuild.

I had this problem today and found this old blog post on how to do this:

http://blogs.msdn.com/b/jomo_fisher/archive/2008/05/22/programmatically-resolve-assembly-name-to-full-path-the-same-way-msbuild-does.aspx

I tried it, it works great! I changed the code to find the 4.5.1 version of the assemblies, when possible, this is what I have now:

#if INTERACTIVE
#r "Microsoft.Build.Engine" 
#r "Microsoft.Build.Framework"
#r "Microsoft.Build.Tasks.v4.0"
#r "Microsoft.Build.Utilities.v4.0"
#endif

open System
open System.Reflection
open Microsoft.Build.Tasks
open Microsoft.Build.Utilities
open Microsoft.Build.Framework
open Microsoft.Build.BuildEngine

/// Reference resolution results. All paths are fully qualified.
type ResolutionResults = {
    referencePaths:string array
    referenceDependencyPaths:string array
    relatedPaths:string array
    referenceSatellitePaths:string array
    referenceScatterPaths:string array
    referenceCopyLocalPaths:string array
    suggestedBindingRedirects:string array
    }


let resolve (references:string array, outputDirectory:string) =
    let x = { new IBuildEngine with
                member be.BuildProjectFile(projectFileName, targetNames, globalProperties, targetOutputs) = true
                member be.LogCustomEvent(e) = ()
                member be.LogErrorEvent(e) = ()
                member be.LogMessageEvent(e) = ()
                member be.LogWarningEvent(e) = ()
                member be.ColumnNumberOfTaskNode with get() = 1
                member be.ContinueOnError with get() = true
                member be.LineNumberOfTaskNode with get() = 1
                member be.ProjectFileOfTaskNode with get() = "" }

Why not just call msbuild for your project or solution file, pass its extension / v: d and parse the output file for the necessary information? For example, for each build resolution, you will see the following:

  Primary reference "System.Data, Version = 2.0.0.0, Culture = neutral, PublicKeyToken = b77a5c561934e089".
      Resolved file path is "c:\WINNT\Microsoft.NET\Framework\v2.0.50727\System.Data.dll".
      Reference found at search path location "{TargetFrameworkDirectory}".
          For SearchPath "{TargetFrameworkDirectory}".

If you get a free copy of Reflector , you can examine the internals of the MSBuild.exe file. I notice that there is a class

Microsoft.Build.Shared.TypeLoader

which has a method called

internal LoadedType Load(string typeName, AssemblyLoadInfo assembly);

who can help?

In any case, with a reflector, you can get the code and, hopefully, reuse the system directly.
