This targets file allows MSBuild projects to invoke the Sing# compiler.
It can also be configured to run the C# compiler, with nearly the same
arguments.  This targets file also handles building dependent projects,
as well.

Most projects should not directly import this file.  Instead, they should
import a .targets file that sets up the correct environment for the project.
For example, App.targets is appropriate for most apps and app-mode libraries,
while KernelLibrary.targets is appropriate for assemblies that are linked
into the kernel.

Projects that use this .targets files can define any of the following properties.
Where possible, this file uses the same properties that the VS2005 C# project
designer uses.  (For example, AssemblyName, AllowUnsafeBlocks, etc.)  Not all
of the VS2005 properties are supported, and this .targets file also makes use
of properties that are not supported (or meaningful) for VS2005.

  * OutputType - "Exe" or "Library".  REQUIRED.  "WinExe" is not supported.

  * AssemblyName - The name of the assembly, without an extension, e.g. "ipconfig".
    REQUIRED.

  * AssumeFieldsNonNull - Specifies whether the compiler should assume
    that all fields are non-null.  The default value is "true".

  * UseMsilToSource - if set to true, compilation happens in two
    stages.  A PrelimAssembly (library) is created from the original
    sources.  ProcesMsil steps are then invoked to generate source code
    based on that library.  Finally, a FinalAssembly is compiled based
    on the original flags, referenceing the PrelimAssembly.  Default is
    ''.

  * PreSourceAssemblyPath - The name of the assembly that results from
    compiling the provided sources (@Compile, etc.).  If
    UseMsilToSource is not set to 'true', then the
    PreSourceAssemblyPath will be the same as the PreRewriteAssemblyPath

  * MsilToSource - a list of Targets to be invoked after the
    PreliminaryAssembly is created but before the FinalAssembly is
    created.  These typically process the preliminary assembly to
    generate additional source files for inclusion in the FinalAssembly.

  * UseMsilRewrite - if set to true, the compiled assembly is rewritten
    using the MSIL-to-MSIL target in MsilRewrite.

  * PreRewriteAssemblyPath - The name of the assembly that results from initial
    compilation, including the optional MsilToSource phase if present.
    If UseMsilRewrite is not true, then this is the same as OutputAsemblyPath.

  * MsilRewrite - a list of Targets to be invoked after the OutputAssembly
    is created to modify the MSIL from the OutputAssembly to create the
    FinalAssembly. NOTE: At the moment this only supports a single such target,
    since it does not set up a pipeline of rewriters.

  * NoStdLib - If set to "true", specifies that the current assembly
    does not reference the standard library.  See also the Stdlib
    property.

  * Stdlib - Specifies the path of the standard library.  For processes,
    this is usually $(APPRUNTIMEDIR)\Corlib.dll.  For kernel libraries,
    this is usually $(KERNDIR)\Kernel.exe.  Note that projects should
    usually not set this property directly; instead, they should import
    the App.targets or KernelLibrary.targets files.

  * CompilerPlatformVersion - The CLI version to use.  This is usually "cli1".

  * CompilerPlatformDir - The directory that contains the standard
    platform libraries, such as Microsoft.SingSharp.Runtime.dll.

  * DefineConstants - The list of #define constants to define.  This
    list should be separated by semi-colons (';'), should not contain
    any spaces, and should not contain any repeated semi-colons (';;').

  * ProjectGuid - Uniquely identifies this project.  OPTIONAL

  * ShadowAssemblyPath - Causes the /shadow:<filename> parameter to be added.

  * NoNullCheck - If set to 'true', disables all null checking.

  * Precompiled - If set to 'true', the Compile item list is ignored, and instead
    of running the compiler a precompiled assembly is copied from the PrecompiledPath
    location. This is useful for shipping certain IP-sensitive components as MSIL only.

  * PrecompiledPath - If Precompiled is 'true', the path where the precompiled assembly
    can be found. The name should be the same as the name of the assembly that would
    be built if Precompiled were not true. Defaults to the project file's directory.

Projects that use this .targets file can define the following items:

  * Compile - The names of source files (usually .cs or .sg) to compile.

  * ProjectReference - The path of an MSBuild project.  This .targets file
      will automatically build the referenced project, and will then add
      a reference to the output of that project to the input of the current
      project.

  * Reference - The path of an MSIL file, which the current assembly will
      reference.  This allows you to declare a reference, but the reference
      will NOT be tracked by the inter-project dependency checker.  In other
      words, it's up to you to make sure that the referenced assembly exists,
      and is up to date, when you use "Reference" items.

  * DependentProject - The path of an MSBuild project.  This .targets file
      will automatically build the referenced project, but will not add a
      reference to its output.  This is useful for projects where you have
      more knowledge about dependencies than MSBuild does, or you are doing
      something fancy.

  * GeneratedSources - source files that are generated after the
      PreliminaryAsssembly is created.  These will be included in
      compilation of a FinalAssembly.  This itemSet is only relevant if
      UseMsilToSource is 'true'.


Targets
=======

Projects that use this .targets file can define the following targets.
All targets should be defined AFTER importing this file.

  * AfterBuild - Invoked as the last dependency of the "Build" target.
  * BeforeBuild - Invoked as the first dependency of the "Build" target.

  This target builds all of the projects that the current project references.
  This target also generates the assembly references for thos projects.

  There are two separate phases of compilation, for executable projects.
  The first is compiling source code to IL.
  The second is compiling native code from a set of IL assemblies.

  Some referenced assemblies are only part of the first phase, some are part
  of the second phase, and some are part of both.  The makefiles distinguished
  them by using the APP_DLLS, APP_ILLS, and SYS_DLLs.  This requires that each
  project that references a DLL put the referenced DLL in the correct list.

  This .targets file handles this differently.  All referenced assemblies are
  pulled in using "ProjectReference" items.  Each project can declare which
  phases of compilation it should be involved in, using properties that it
  sets before importing this .targets file.

  If an assembly sets the ExcludeFromNativeReferences property to 'true',
  then that assembly will not be passed as a reference to Bartok.

  If an assembly sets the ExcludeFromILReferences property to 'true',
  then that assembly will not be passed as a reference to CSC/SGC.

  This information is passed between projects as metadata on the output items
  of the "Build" task.  This task looks for those items, and builds references
  for the different phases appropriately.  The "Reference" item set is used for
  IL references.  The "NativeReference" item set is used for native code
  references (those passed to Bartok).

  This target processes BinaryResource items, if any.  It creates temporary source files
  (in the OutputPath dir), using mkasm.exe.  The generated source files are then compiled
  into a satellite assembly, named $(AssemblyName).Resources.dll, and that satellite
  assembly is added as a reference to the project assembly.

  We *could* just add these generated source files directly to the Compile item set, which
  would cause these files to be compiled directly into the current project's assembly.
  This works; however, the Sing# compiler is significantly slower when processing these
  files.  So instead, we create a resource assembly, using the C# compiler, and add that
  assembly as a reference to the current project.

  This is a batched target.  This entire target runs once for each group of BinaryResource
  items that have the same combination of values for the metadata tags Namespace, ClassName,
  FieldName, and Args.  This means that, if you declare more than one BinaryResource item
  that has the same namespace and class name, then they will be compiled into the same file.

  The following metadata fields are REQUIRED for all BinaryResource items:

    Namespace - Specifies the namespace of the class generated.
    ClassName - Specifies the name of the class generated.
    FieldName - Specifies the name of the field generated, whose contents are the binary resource.

  The following metadata fields are OPTIONAL:

    OutputAsArray - If set to 'true', then mkasm will generate a byte[][] field, rather than byte[].
    Args - Passed directly to mkasm, without interpretation.

  Example:

  <ItemGroup>
    <BinaryResource Include="Resources\*.wav">
      <ClassName>WavAudio</ClassName>
      <Namespace>Microsoft.Singularity.Applications</Namespace>
      <FieldName>AudioData></FieldName>
      <OutputAsArray>true</OutputAsArray>
    </BinaryResource>
  </ItemGroup>

    <!--
    Ok, this is ugly, but I can't see a prettier way to do this.  We want to allow projects
    that declare BinaryResource items to be able to specify whether the binary resources are
    encoded as byte[] or as byte[][].  This is controlled by the /l option of mkasm.  One
    approach that works, is to allow projects to declare a metadata tag 'Args' which is simply
    passed directly to mkasm.  We do pass this metadata tag now, but it has a distinctly
    un-XML-ish flavor.  We want to allow projects to control this behavior with a metadata tag,
    such as <OutputAsArray>true</OutputAsArray>.  But there is no easy way to map that metadata
    tag to different values, within the invocation of a single <Exec> task.  So we use two
    <Exec> tasks, which are nearly identical except that one has "/l" in its command line, and
    both have conditions that prevent them both from running.

    This works, but it means that if we need to add any other metadata tags that map to command
    line options for mkasm, we will have an exponential number of tasks, with the condition on
    each task being some combination of build parameters.  That's nasty.
