Well, what I ran into makes no sense. Yesterday I was viewing the report form within my web site just fine. Today I tried to change it to an embedded report, and I started getting crazy errors, like this:
So, I reverted all of my changes...and...yep, the error message still exists. I've gone as far as removing the entire folder from my local drive and getting a fresh copy from VSO.
I am not the only one with this EXACT error:
Any help would be appreciated.

Thank you for the information.
Unfortunately I did not upgrade report builder/viewer between the time that it worked and when it stopped working. However, I'm going to try un/reinstalling and see if it helps. I'll report back once I have tried this.

Based on this link:
I followed this other link to what worked for me:
The solution was to add this to the web.confg system.webServer.Handlers:
<add name="Reserved-ReportViewerWebControl-axd" path="Reserved.ReportViewerWebControl.axd" verb="*" type="Microsoft.Reporting.WebForms.HttpHandler" resourceType="Unspecified" />
I do not understand why I have to do this because last Wednesday my report worked just fine without it. I am not going to mark this as answered until I have a real answer from someone.

I have an answer, but I have no explanation as to why this worked Wednesday but not on Thursday. The project in which I added my report viewer had an existing reference to an older report viewer. I really can't believe it didn't result in some more specific
The reason the other add worked is that it has resourceType=Unspecified. So the real solution for me was to change my handler to this:
<add name="ReportViewerWebControlHandler" preCondition="integratedMode" verb="*" path="Reserved.ReportViewerWebControl.axd" type="Microsoft.Reporting.WebForms.HttpHandler" resourceType="Unspecified"/>
