Use dotPeek from within Visual Studio without ReSharper

With dotPeek, I haven't found a way of integrating it into Visual Studio, so that you can view the decompiled source of some code. There is an option to add dotPeek to the right-click menu in Windows Explorer, so you can click on a DLL file and open it in dotPeek, but it's not the same experience as inline within Visual Studio.

Apparently ILSpy does have an addin which hooks into Visual Studio, though I've not used that addin myself. ILSpy is a fantastic alternative.

From dotPeek 2019.3.2 at least, an option exists to integrate dotPeek to Visual Studio.

EDIT: I've looked into this option and, what it seems it only do, is that within dotPeek, it allows you to export a dll into a visual studio project. So this does not answer your question, sorry.
