Issues with Debugging Shibboleth-protected Web Application

[Galuzinschii, Svetlana]

Hello Shibboleth Users!

I hope you can help me figure out how to make Visual Studio (VS) Professional 2013 (Update 2) or VS Enterprise 2015 (Update 2) debug a Shibboleth-protected application without manually attaching to the IIS process. I have a full IIS 7.5 installed on my developer workstation. I successfully (or so I think) installed the latest Shibboleth-SP on my developer machine and configured it to require authentication for  a web application. If I launch that web application without debugging, shibboleth authentication works fine.  I configured my VS to use the local IIS (not IIS express that comes by default with VS) as a web server.  If I start debugging (in VS 2015 or 2013) when Shibboleth-SP is being enforced for this particular web app, I get the message 'Unable to start debugging on the web server. Operation not supported. Unknown error: 0x80004005.' Nothing that I found about this type of error resolved my issue. As soon as I remove the web app from being 'protected' by Shibboleth-SP in shibboleth2.xml, I can start debugging just fine from VS 2013 or 2015. When Shibboleth-SP is 'protecting' my application, I have to launch the web app without debugging and then attach to the IIS process manually through VS debugging tools.

The goal is to just click start debugging in VS and debug my web app without manually attaching to the IIS process running it.

Any ideas are extremely appreciated!

Thank you,
