[C#] EAP-Resharper for VS-2022 Patch with DNLIB

[Succubus]

If you like this product please buy it It's quite cheap and c# and c++ ReSharper is nice, Matti introduces this to me at discord.

This works on early access only which is ReSharper for vs2022 but you can edit it to make it work to a stable release one. by just telling this program where to find the DLL I use the registry to find the early access path so that's the hint

Early Access - This version is not smooth yet because early access

Stable Release for vs2019 - This one is fine

In theory, all ReSharper products will auto-registered
since they share a single licensing module.

whenever u update or uninstall or install another product under ReSharper you need to patch it again.
because they reinstalled the license module. I think it's for security measures.

Updated works with EAP 8 above now

Added fixed for EAP 8

Nice Part of Coding "//File.Copy(file_temp, file+".fuck", true);"


One question , can it be use on other prodcuts ? i am learning GoLang and they have something special product for it.

Are you talking about https://www.jetbrains.com/go/ ?

Well, thats not part of ReSharper bundle so no.

The list of products includes

Resharper .NET
Resharper C++
Rider - Unreal Engine IDE
DotTrace - Profiler
DotCover
DotMemory
DotPeek

[Debugger]

Hi Succubus,

For this code work out with other jetbrain resharper tools like rider or dotmemory, or others mentioned, what needs to be done?

I tried pointing it to dotmemory standalone applicatiom, but it seems not working?

Any pointers?
