Is there a more specific type that we can use?

Please add a doc-comment.

There is no more specific type we can use. I'll move this method to Incremental hash, since it's not really general purpose. Comment added.

Feedback addressed. Any more suggestions? |

I am still not comfortable with returning null for all algorithms, but SHA1. What happens if other algorithm is requested? If we support only SHA1, then public API shouldn't pretend that this is not the case, by allowing to request different algorithm.

Alternatively we should throw for other algorithms.

It's not public API. It's private to the IncrementalHash implementation.

LGTM, modulo the issue with TryGetHashAlgorithmNameObj raised above. |

#9699 ported to future.
Refactors PeWriter into components independent of Roslyn, so that it can later be moved to System.Reflection.Metadata in CoreFX.
The goal is to provide PE/COFF builder and ECMA-335 metadata builder that can be used broadly to write managed and native PE files. The goal is not to immediately provide the full support for writing all existing sections of the PE/COFF format but rather to enable composing PE/COFF files from section blobs and to provide builders for sections commonly appearing in managed PE files.
Includes implementation of a set of types, blob encoders that can be used for serialization of various blob structures found in the ECMA-335 metadata (especially signatures). The introduced abstraction provides type-system enforced structure to the blobs with minimal runtime overhead.
More work will follow to polish the public surface of the builders and serializers.
