[gme-users] About Add On Written in C# Activation Problem in GME

[Kevin Smyth]

Hi Somesh,

When the addons are restarted because you modified the active addons in
Tools>Register Components, the current addon is removed when IMgaAddon has
the final release or Destroy() is called. I think this is the proper way to
do this for C# addons:

diff --git a/Test_Project.cs b/Test_Project.cs
index fe7ba8a..a40ab55 100644
--- a/Test_Project.cs
+++ b/Test_Project.cs

         #endregion
     }



I'll update the templates in GME's C# component wizard.
