From the tests we did, we were in doubt as to whether the new version is performing worse than the previous one, perhaps there was an external factor that may have induced this perception.
on the other hand, we can say that with regard to performance, we have not improved with it.
Claudio, this is very odd because my optimization was mostly related to freeing memory when closing the files. I think in old versions it could cause increasing memory and SystemOutOfMemory exception at some point. We didn’t do any major changing that could cause loosing of performance.
Also I wanted to make sure you are using the latest build which is 10.0.0.2620. And if you still have crashes with it?
We were able to isolate what is happening at the opening of the project. see the attached example project, it appears to be looping in the reference WebApplication1.rar (37.8 KB)
After opening expand the references and keep watching, it will be possible to notice the references moving.
Another detail that may interest you, our solution has several projects, web and desktop, we realized that separating the solutions in separate desktop projects from the web projects, improved the memory consumption. It was at this point that I realized that the problem was related to a looping while loading the reference I mentioned (System.Web.Extensions).
