I am using a rather old .NET application and trying to update it to the latest version. I was able to upgrade it to .Net 4.0 and make it work with VS 2010, however, when I upgrade to VS 2013, none of the Crystal Reports reports appear while working with the Studio's built-in web server (in fact, I did not understand IIS, but I hope this works). I tried to do some research on this, and some people got an error similar to mine that crdb_adoplus could not find or load pdb files and stated that adding the following to web.config helps:
<startup useLegacyV2RuntimeActivationPolicy="true">
<supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.0"/>
</startup>
but i'm not worried about acceptlus debugging, and it still does nothing for me. To be specific, the page loads, but where there should be only empty space in the report and no other real errors in my journal. Any ideas would be helpful.
