"Unable to create type CLRMDActivator"

loop-evgeny commented 4 years ago

Just tried netext for the first time on a .NET Core dump. It went like this:

0:000> .load netext
netext version 2.1.51.5000 Nov 22 2019
License and usage can be seen here: !whelp license

I did extract the x64 version of netext into C:\Program Files\Debugging Tools for Windows (x64), as instructed. (NetExtShim.dll is there, too.)

Hi Loop,

It is not necessary to have NetExt on the same folder of Debugger anymore. Are you using WinDbgX (the new beta version) or the classic WinDbg? Can you show me the the output of: lmv m coreclr And: .coredll -l

Thanks,

Rodney

I'm using the classic WinDbg: 6.12.0002.633 (x64).

I am on vacation far from my computer, I misspelt the command, it was supposed to be .cordll -l However, you will need a much more modern WinDbg (10.x) that is installed via SDK, you may skip all other SDK installation and only install Debugging tools. See more here: https://blogs.msdn.microsoft.com/rodneyviana/2015/03/10/getting-started-with-netext/

Also you need at least .NET 4.5 on your machine.
