Support for roslyn

[3F]

the request about official support of this feature, here:

• c# adding [DllExport] feature #1013

and:

If you prepare a pull request, please call it to my attention and I will shepherd it.

so, TODO

[den-run-ai]

Does this include .NET Core and non-Windows platforms?

[3F]

well, it probably should include some changes also for coreclr if you meant this.

I did not look this feature in details 'what and where' we should change, however, mainly I don't want to use this important feature via ILAsm only o_o

I already wrote to Robert that's crazy why the MS do not want to support this initially, or why this only as part of ILasm (the features via .export directive from ILAsm, seems starting with 2.0)

The current DllExport as flexible option instead of manual changing, but it still requires a few ugly things: the any modifying of references (to remove our assembly from final dll), external executable ildasm/ilasm, and generally the external dependency at all.

Therefore, I have more priority task to develop the new way to avoid all of this inconvenience: Improvements for roslyn & coreclr and/or the any direct modifying of assemblies instead of ildasm/ilasm.

currently I have no time for this :( so it will be considered only later

updated:

I also added short info in readme.md where to look implementation of this features (ILAsm .export directive)

source code:

• coreclr/ILDasm
• coreclr/ILAsm
