new Dictionary<T,T> throwing System.OutOfMemoryException exception #111

Closed se closed 3 years ago

se commented 3 years ago

new Dictionary<string, object>() is throwing exception.

Sample Code

var context = new EvalContext();
context.RegisterType(typeof(MSMRAccountAccessRequest));
context.RegisterType(typeof(MSMRBrowserActionTypes));
context.RegisterType(typeof(MSMRBrowserAction));
context.RegisterType(typeof(Guid));
context.RegisterType(typeof(List<>));
context.RegisterType(typeof(Dictionary<,>));
context.Execute("var values = new Dictionary<string, object>();");

Exception

Trying to apply a workaround but no chance right now. It is an urgent situation for us.

Hello @se ,

Sorry for the delay, my developer tried it and everything is working without problem.

Where the issue happens is pretty weird on the GetTypeByName.

Is it possible to provide a runnable project that throw the exception? We will for sure fix it asap if we can reproduce it.

You can send the project in private here: info@zzzprojects.com if needed.

Best Regards,

Jon

Hello @se ,

Since our last conversation, we haven't heard from you!

As mentioned in my previous message, Would it be possible to send a private project that throws the exception to info@zzzprojects.com so we can fix the issue?

Looking forward to hearing from you,

Jon

Sorry. I fixed with a workaround. I'm gonna try to create a new private project and reproduce the issue.
