Upgrading VS 2022 solution from Rhino 7 to Rhino 8 SDK

Rhino Developer

I just completed the steps described here in order to upgrade to Rhino 8 SDK

I would like to ask what the steps are to be followed in order to build and run my Rhino 7 VS2022 solution in Rhino 8.
Thanks!

Might this guide be useful?

My plugin seems to build and run properly now in Rhino 8, but when exiting Rhino 8 while at debug mode I get the following exception:

Is there something missed when configuring the Rhino 8 upgrade?

I investigated further more this issue. I followed the steps described here:

and here

But I didn’t see any change, the exception kept on coming.

In the output window I get at both Release/Debug configuration:

Exception thrown at 0x00007FFE9DEB1EE3 (rdk.rhp) in Rhino.exe: 0xC0000005: Access violation reading location 0x0000000000000000.

I rechecked everything:

  1. My plugin works properly in Rhino 7
  2. The plugin works properly in Rhino 8 if I run Rhino 8 directly (not via the VS2022 debugger)

Then I thought that something is wrong when the Rhino 8 is called via the VS 2022:

  • I uninstalled all of my custom plugins
  • I created a new plugin from the template in VS and I ran the debugger.

Rhino 8 starts properly. Instead of installing the new empty plugin I just hit directly the close x to close the Rhino 8 app.
Then again I get the same exception while exiting:

Exception thrown at 0x00007FFEA0B61EE3 (rdk.rhp) in Rhino.exe: 0xC0000005: Access violation reading location 0x0000000000000000.

Hence I realize that something is wrong when VS2022 calls the Rhino 8.
Is there a way to fix this?

@andy you may want to investigate this. It looks like a potential bug in our code

Could it be that somehow the Symbol file locations is messed up in my VS2022 installation?
The exception in “More information” is looking for the pdb file in various locations:

C:\Program Files\Rhino 8\System\rdk.pdb: Cannot find or open the PDB file.
C:\Program Files\Rhino 8\Plug-ins\rdk.pdb: Cannot find or open the PDB file.
D:\BuildAgent\work\dujour\src4\bin\Release\Plug-ins\rdk.pdb: Cannot find or open the PDB file.
C:\Users\xxx\AppData\Local\Temp\SymbolCache\rdk.pdb\b50b356a97ec43c392eeebec0479ada11\rdk.pdb: Cannot find or open the PDB file.

Is there a guide of how to set up the symbols properly for Rhino 8 in VS2022?

is there an update on this issue? I haven’t managed to exit debugger without a rdk.rhp exception so far.
