c# - Enable-Migrations Not Working Because of the Windows on Mac -


i mac user want develop c# via visual studio. therefore, have parallels account programme switching os windows while using it.

firstly, let me introduce error getting: (trying package manager console inside of nuget package manager)

cannot determine valid start-up project. using project 'codefirstnewdatabasesample' instead. configuration file , working directory may not set expected. use -startupprojectname parameter set 1 explicitly. use -verbose switch more information.

vs2015 downloaded on system. have model class , local database on want able change database via migrations. however, i'm having trouble achieving , think reason behind fact windows in on mac this question suggests. thought in way because when wanted access visual studio projects on windows system, entered directory named home on 'mac'(y:) under network location (the exact path followed computer->home on 'mac'(y:)[under network location tab]->documents->visual studio 2015). again, answer in question suggests, cut , paste desktop of windows system. later realized, able reach desktop network locations tab in computer directory.

i hope had same trouble before , solved can me it.

waiting answers,

thanks,

i have same configuration (osx + parallels) , had same problem you. when source code on osx shared folder ef package manager console throws message. , link states, problem not mac+parallels having code on network location.

if move code vm's desktop, maybe it's still network location if paralells configured share desktop between mac , windows. try pure windows location, c:\vsprojects

i ended moving code windows location, worked better me, if want keep code on network folder need use -startupprojectname , specify executable project there explicitly.

i need modify .htaccess file redirect urls https version without "www". http://example.com --> https://example.com http://www.example.com --> https://example.com https://www.example.com --> https://example.com this how .htaccess file looks like: rewriteengine on rewritecond %{request_filename} !-d rewritecond %{request_filename} !-f rewriterule ^(.*)$ redirect.php?id=$1&page=$2 [qsa,l] what modifications need make .htaccess in order forward https without "www"? it depends on doing current code. looks file called redirect trying display php page seo friendly url. think might confusing people. anyway, need , force https without www, need 1 more rule above. also second rule needs two capture groups in rewriterule test string because wanting 2 different values using $1 , $2 references. rewriteengine on #rediect www non www and/or http https --- combinations. rewritecond %{http_host} !^example\.com [nc,or] rewritecond %{https} !^
