Support for Xamarin compressed files

[jklnz]

Some files compiled by Xamarin are compressed with LZ4 (see dotnet/android#4686) - would it be possible to add support for this? Another Github user has provided a Python file to decompress it, but it would be nice if it was built in to dnSpy.

The other repo that uses Python is: https://github.com/NickstaDB/xamarin-decompress

I will probably implement this together with #16 as these feature are quite similar.

Hi, could you provide an example file where this compression is used?

Thanks in advance!

Hey,
I have attached four DLL files that I believe are compressed with it.
Thanks

Hi, would writing to this compressed format also be required? I have already implemented decompression logic for these files locally but I don't know if the File -> Save command should recompress the module when saving?

[jklnz]

Hey ElektroKill, I personally would not need it to be saved with compression. I like to look at what is inside... So no compression is probably fine!

Hi, this feature will not be implemented into 6.2.0. The complexity of implementing it properly (having hex editor, saving, debugging support, etc. working correctly) is much harder than I initially thought paired with the limited interest in this feature. This will be put on hold for now. Sorry!

Hi ElektroKill - thanks for letting me know, that is no problem at all.

I have created a c# script to Decompress these files for easy of use. https://github.com/adricl/Xamarin-Dll-Decompressor
