Is there a possible way to do .NET injection without C++?

[zys924]

The common way to do .NET assembly injection into an unmanaged process is by a BootStrap dll written in unmanaged C++, in which the CLR is initialized and used to load the .NET assembly. Here, what the injector has done is simple: CreateRemoteThread, and is capable to be implemented either in C++ or C#. However, the BootStrap dll seems to have to be unmanaged.

My question is: is there an approach to "skip" the BootStrap dll somehow to make the entire procedure fully managed? In other words, a managed method to load the CLR into the target process?

I have a vague impression about such a solution somewhere in the forum before, using ASM, whereas search has helped little so far. If anyone knows about any clue, thank you in advance!

Yes, you can do that, but it will require editing IL code or use Unmanaged Exports.

I got this to work with a domain manager as well, if you want you can take a look at the project here: https://dl.dropbox.com/u/6467709/Ownedcore/Dysis.rar
Maybe this can help you out.

Thanks for you guys' kind offer!

Maybe you can do it as well without an CLR, If you could work with it, it is just as easy as wrapping fasm.dll and using P/Invoke
