Odd DLL version numbering preventing debugging

[Infarinato]

I do apologize in advance for the very trivial question, but need to debug a pesky Sitecore/OWIN/SAML single logout issue, where the authentication user principal is getting dropped at the request stage —I already know it’s neither a Microsoft.Owin nor a Sustainsys.Saml2 issue, as virtually the same configuration is used in a sample MVC app, where everything works as expected, but I do need to look inside the Microsoft.Owin.Security.AuthenticationResponseGrant method to see what’s actually happening (verbose logging doesn’t really help me).

So, I have downloaded the latest 4.2.2 release hoping to recompile the sources in non-optimized mode. Recompiling works fine, but, whereas the generated Product Version is correctly 4.2.2, the File Version gets set to an odd (for me, at least!) 42.42.42.42424, so of course this won’t get recognized as the right version (and manually changing the version would of course mess up the strong name signature).

Does anyone know how I can get the solution to generate the correct file version number? Otherwise, if the non-optimized versions of the Microsoft.Owin DLLs are already available somewhere, I’d be grateful if someone could let me know where I can find them. 😊

Many thanks.
