Glimpse causes StackOverFlowException on Web Forms Site

Question

I installed Glimpse 1.7.0 for my Web Forms site, but when I turn it on, the Web Forms site encounters a StackOverflowException. Stack trace is as follows:

Is there a way to remedy this error?

Answer 1

We have a known issue that has already been fixed, but is not yet released.

You could in the meanwhile use our latest WebForms NuGet package which has the updated code, but be aware that the version number has not yet changed, that is only done when the package will be released, but at least it should solve your problem.
