“Ambiguous match found” in a Web Control - a Possible Bug

January 29th, 2007 | Category: asp.net, development, web

If you use ASP.NET AJAX you might come up with this error popup - “Ambiguous match found”.

The issue here is that you have 2 variables that are named the same but have different casing. You have to rename the variables to have different names. Changing from protected to private will not help.

    Thanks for this. I was trying to send a JSON serialized object back through an Ajax webservice, and this help me with a direction greatly.
