entity framework navigation properties joins different sql produced from different applications -


in 1 web application using :-

    using (mvcapplication1.models.plumsoftwareentities db = new models.plumsoftwareentities())     {        var results = (from p in db.work_details                 p.companyid == 2                 select new { p.id, p.dated, p.employee1.abbrev, p.activity.activitycode }).tolist();     }

and produces sql:-

    select      [extent1].[id] [id],      [extent1].[dated] [dated],      [extent2].[abbrev] [abbrev],      [extent3].[activitycode] [activitycode]       [dbo].[work details] [extent1]     inner join [dbo].[employees] [extent2] on [extent1].[employee] = [extent2].[id]     inner join [dbo].[activity] [extent3] on [extent1].[activitycodeid] = [extent3].activitycodeid]     2 = [extent1].[companyid]

in web application use same linq above except produces sql:-

    select      [extent1].[id] [id],      [extent1].[dated] [dated],      [extent2].[abbrev] [abbrev],      [extent3].[activitycode] [activitycode]       [dbo].[work details] [extent1]     inner join [dbo].[employees] [extent2] on [extent1].[employee] = [extent2].[id]     left outer join [dbo].[activity] [extent3] on [extent1].[activitycodeid] = [extent3].activitycodeid]     2 = [extent1].[companyid]

the last navigation property left outer join

what setting, explanation there behaviour.

the connection strings same, same sql server, same login, using same entity framework 5 in both applications, both running asp.net 4.5

this simple example , reason matters me left outer join projecting entity tables onto dto objects using navigation properties caching these queries using sqldependency. sqldependency requires view must use inner joins otherwise error thrown.

solved microsoft update kb2805227 (http://support.microsoft.com/kb/2805227) released may 2013 .net4.5 caused issue me. uninstalling solved issue.

keyboard - C++ GetAsyncKeyState alternative -

i using windows.h library's getasynckeystate function define key pushed on keyboard . here program returns int value of pushed key example. #include <iostream> #include <windows.h> using namespace std; int main (){ char i; for(i=8;i<190;i++){ if(getasynckeystate(i)== -32767){ cout<<int (i)<<endl; } } return 0; } but trying make opengl simple game , function appeared slow . there function not need cycle 180 times , if statement . thanks you're trying make opengl game, you're going use glfw. if that's case can away using glfwgetkey() such: if (glfwgetkey(glfw_key_up) == glfw_press) {...} if (glfwgetkey(glfw_key_down) == glfw_press) {...} that method nicely explained in tutorial 6 opengl-tutorial.org . should start first tutorial of beginners tutorials , later intermediate tutorials . if you're going make win32 window can listen wm_keydown or wm_keyup messages , virtua
