Hi again dlemstra!
I have tried the code in a console application. Precisely, I have created two console application, in one I work with the variable "Hoja_trabajo_1.pdf", and in the other I work with the variable "Hoja_trabajo_2.pdf". If I run the two console applications at the same time, it works, that is, it has been created "Hoja_trabajo_1.png" and "Hoja_trabajo_2.png".
Until this point, the application works fine.
But at the moment, when I put the code in two web applications (one for "Hoja_Trabajo_1.pdf" and other for "Hoja_Trabajo_2.pdf") and I run these applications under the same application pool in a IIS 7, I get this error Object reference not set to an instance of an object when I create Dim horizontal As MagickImage = images.AppendHorizontally() again.
I also prove to run these applications under different application pools. In this case, it works fine.
What could be the problem?
Thanks in advance.
