Thank you for your hint Scott. I tried it and it drives me even more crazy,
since in the debugger it works, but the same line "at runtime" fails.
I put a breakpoint before the line, and inspected the Session variable:
?System.Web.HttpContext.Current.Session["BackEnd"]
{BackEnd}
System.Object: {BackEnd}
con: {com.Transoft.TCA.TCAConnection}
looks okay, so I went ahead and assigned it to my private field, casting the
session variable:
this.backend = (BackEnd)System.Web.HttpContext.Current.Session["BackEnd"]
{BackEnd}
System.Object: {BackEnd}
con: {com.Transoft.TCA.TCAConnection}
and it works as well !!!
But now comes the thing I don't understand: if I step to the next statement,
which is exactly what I entered in the debugger window, it fails with the
Specified cast is not valid
message.
