Hi there,
We've deployed an ASP.NET web application into Azure App Services. We found out that EO.Pdf crashes very often and the only way to solve the problem is to restart the Azure App Services. The library we are using currently is EO.PDF for .net. Here is the error we got.
Can you please advise whether or not this library works well in Azure App Services (not Azure VM). If not, what kinds of solution can you provide? We have found a few similar cases reported to this forum and there was no good solution so far.
Thanks,

Hi,
We are aware of this issue but we have not been able to reproduce it. We believe the issue is related to Azure App Service recycling AppDomains. Based on that we have thoroughly reviewed our code related to AppDomain unload and we do have an internal build that addressed a number of issues we have discovered in that area. We have tested the internal build on simulated AppDomain recycling scenarios (through test code) and it did pass those test. However we have not been able to positively verify it in Azure App Service environment since we do not have a reliable way to reproduce it.
We can provide you the internal build for you to run in your environment if you are interested. Alternatively, if you have a way to reliably reproduce this problem we would appreciate if you can share a test environment or test code with us. In that case we can run the test from our end as well.
Thanks!

Yes, please let us know the internal build. We can give it a try.
