DLL with gui in metin2

[Vadciox 0]

Hello everyone,

I wonder that How can I add windows form to dll and I found it ( with clr )

If I inject my dll which has windows form to randomly program, the windows from appears. But I cant inject it to metin2 with extreme injection ( https://resimyukle.io/r/Oj74Q3fsJt )

Is there other way to make dll with include gui or How can I solve this problem
