To be honest, I think this one was much easier than the first. No IDA, CFF Explorer, anything like that. Just ILAsm and ILDasm. Pretty easy, I just changed the MainForm to Form2 and added the MySettings.var1 = true in the entrypoint method, and the job is done.

@Ufo-Pu55y:

No, I didn't.

This is how is suppose to be.

Some hard crackme will come later :-)

Some hard crackme can be done by obfuscation, take a look at:

The problem whit this crackme is that many people crack this one by guessing, take a look at:

I don't like cracking by guessing so here comes "Net Crackme 3":

--------

Is this crackme medium?

Depends on which method you use, If you use ILDASM/ILASM is very easy,

if you use ILDASM + a hexeditor is a little harder.

P.S.:

@Ufo-Pu55y:

If you have some hard crackme (some of your old projects) give a PM whit a link to them.

I want to solve them.

Cheers,
