Ok Daniel,
I replaced RxNet 1.0.1.4 with your debug one.
When starting Bricscad I see in the command prompt:
Loading .NET runtime v2.0.50727
RxLoader.txt = C:\Program Files\RxNet\V9\RxLoader.txt
Shouldn't that be the path of the DLL I'm trying to load??
(D:\VOSS.NET\VOSS\VOSS.CAD.Bricscad.RxNet\bin\Debug\VOSS.CAD.Bricscad.RxNet.dll)??
