EDIT: An extension for VS 11+ is available @ https://github.com/Trass3r/DevUtils
I solved it myself by creating a nice macro. It's way more sophisticated but basically works like this:
Imports EnvDTE
Imports Microsoft.VisualStudio.VCProjectEngine
Dim doc As EnvDTE.Document = DTE.ActiveDocument
Dim prj As VCProject = doc.ProjectItem.ContainingProject.Object
Dim file As VCFile = prj.Files.Item(doc.Name)
Dim fileconfigs As IVCCollection = file.FileConfigurations
Dim fileconfig As VCFileConfiguration = fileconfigs.Item("Release|x64")
Dim tool As VCCLCompilerTool = fileconfig.Tool
Dim asmFile = System.IO.Path.GetTempFileName + ".asm"
tool.WholeProgramOptimization = False
tool.AssemblerOutput = asmListingOption.asmListingAsmSrc
tool.AssemblerListingLocation = asmFile
fileconfig.Compile(True, True)
Dim window = DTE.ItemOperations.OpenFile(asmFile, Constants.vsViewKindCode)
Very useful in combination with AsmHighlighter.
Preprocessed file can be generated similarly with
tool.GeneratePreprocessedFile = preprocessOption.preprocessYes
' there's no separate option for this, so misuse /Fo
tool.ObjectFile = System.IO.Path.GetTempFileName + ".cpp"
