Pls Help, my rider have "URI is not registered" problem

Does it affect compilation?

yeah, I can't even write hello world

Now I see that there were some messages and exceptions in right-down corner. 

Please submit the logs from Help->Show log in Finder to https://youtrack.jetbrains.com/issues/RIDER and follow up here with request link.

Mostly possible it is something about mono is not installed or not new version of mono or mono is not detected.

I can do a teamviewer to you machine, but you would need to send me the id and pass. Ivan.Shakhov at jetbrains.com

Hello everybody!

Error messages in the .csproj are not connected with build problems, this is simply a result of xsd validation. EAP 23 will come with msbuild scheme built-in for xml validation, which will bring smart code completion and quick documentation for tags. However red code for unresolved tags is still possible if your csproj has some custom tags, this will be fixed in the future releases.

Thanks for the feedback, and again this doesn't affect your build, this is simple xml file-bound analysis

Thank you for comment :) 

@Brtktlc sorry, missed your comment with pass and id, I was expecting an email.
