问题 I am getting the following error whenever I try to install Visual Studio Community from the Microsoft site. It occurs immediately upon running the exe . I have downloaded many versions, run as admin, restarted my pc etc etc, and every time I am hit with this error. I have had visual studio installed on this PC previously. Selecting "Close program" ironically opens this site. Which is evidently no help. Does anyone have any idea how I can resolve this before I attempt to contact Microsoft

问题 I have been having an issue recently with Visual Studio 2015 and the only workaround I can find is opening up the developer command line and executing "devenv.exe /resetuserdata" That solves the problem (until the next windows update typically brings it back). I have been trying to troubleshoot this for a while so I can actually determine the root cause but one big issue is that I cannot find any msdn documentation about this command "devenv.exe /resetuserdata" So that is essentially my

问题 While migrating an application from VisualStudio 2005 to VisualStudio 2015 we found a different behaviour in some code that concatenates CString instances when that code is built with VS2015. So, I've created a simple Win32 console application to demonstrate the problem. The console application (using MFC as shared dll and Unicode charachter set) executes this simple function: void f() { CString x( '\0' ); CString r( 'a' ); r += x; CString rr( 'a' ); rr = rr + x; int rSize = r.GetLength();

问题 In the "older" ASP.NET MVC projects you were able to create two separate MVC projects. Use the first project as the "main" MVC project and let that project then reference the second project (with some additional config settings). Basically how 3rd party MVC projects were setup. You reference their assemblies in your own MVC project and you auto-magically have "Admin" pages available as well. I'm currently trying to find out if this is possible for the newer MVC ASP.NET 5 as well. I basically

问题 When I open my worked solution (after merge from other branch) VS2013 shows error message "unspecified error" and I cannot close the window (the error's dialog jumps each time when I close it). VS2012 opens the solution without error messages. I suspect issue related to TFS configuration. How can I found actual reason of the error? 回答1: I have searched a lot about its root cause but couldn't found any concrete information. For me, Deleting the solution's .suo file. resolve this problem. 回答2:
