Unhandled Execution Error

[ttctilsted]

Hi

I am randomly getting this error on a Hello World example-code on a "clean" asp.net project.
The error happens very randomly, with no apparent pattern.
I am using this nuget package:
<package id="Noesis.Javascript" version="0.7.1.0" targetFramework="net471" />

This is the code:

App pool settings:

C++ installations:

If the site starts up without the error, it is able to run like that for a long time. Therefore i created a Powershell script to better provoke the error:

The script will continuously do an issreset and then call the page. The result is about 50/50 chance of getting a 200 statuscode back and getting the error back.

I suspect that this is a cross-threading issue. Try creating your context for each request.

Thank you for your response.

However i am creating my context for each request. The Page_Load method will run for each request.

With some further testing i have found that this only happens when i use the x64 version of Noesis.Javascript.dll.
When i switch to x86 and set "Enable 32-bit Applications" to True in the App pool, i do not get the error.
This is not a fix for me, as i need to be able to run x64.

While I don't have a build/nuget package available yet, I have upgraded to a recent version of V8 and build using VS 2017, so it might be worth retesting this. (Building JavaScript.Net is now easy because we get V8 from nuget.)
