MVC 5 dnx.exe error messages

I have just started learning ASP.NET - MVC 5 and followed quite a few Pluralsight videos on creating these websites.

The problem I have encountered in my Visual Studio 2015 is, that when I am building my app I can see a lot of the following messages under my Output window:

'dnx.exe' (CLR v4.0.30319: DefaultDomain): Loaded 'C:\Users\Robert\.dnx\runtimes\dnx-clr-win-x86.1.0.0-rc1-update1\bin\Microsoft.Dnx.Host.dll'. Cannot find or open the PDB file.

Also I can see, that my Website is loaded much slower than the website that presenters have in the video and I believe it is because of the above mentioned error.

When I run dnvm list command under my command prompt, this is the result that I can see:

Active Version           Runtime Architecture Location                      Alias

  *    1.0.0-rc1-update1 clr     x86          C:\Users\Robert\.dnx\runtimes default

       1.0.0-rc1-update1 coreclr x86          C:\Users\Robert\.dnx\runtimes

Should I change anything under my Visual Studio setup in order to get rid of these error messages, or are these normal?

Those messages are normal. You're attaching the debugger, and for every module it tries to load the symbols. It just tells you that the symbols are not available.
