问题 I receive this error when trying to launch IIS Express from Visual Studio with a project that's configured to listen to an address other than localhost. Visual Studio freezes for about 30 seconds before giving the error "Unable to launch the IIS Express Web server".

问题 Using Visual studio 2010 I got problems when double-clicking, for example a config file (*.config). Visual Studio would open but give me a error message about parameters.

I have now installed Visual Studio 2012 and it has the same problem?! This makes my work a lot harder, it should be easy to just drag & drop files into Visual Studio, but it's not so? Now I

问题 I have migrated a solution that is currently targeting .NET 4.0 in VS2010 to VS2012 and now I would like to re-target it to .Net 4.5 What I am not sure about is the NuGet packages.

问题 Recently, I tried to make a battery app (C#, store app) for Windows 8.1 (I am using VS2013, tried also VS2012 with the same result). As it turned out, I need to add a Reference to the project - but I cannot add anything in Reference Manager: it says "All of the Framework assemblies are already referenced".

问题 I'm very new to SQL Server, Flot.js, working with databases in general. I'm working on a project in ASP.NET MVC 4 (using VS 2012) which has a Microsoft SQL Server Compact 4.0 database filled with data, and I would like to visually display this data using flot.js. I haven't been able to find any information on the general steps one would take to manipulate the data.

问题 Now I having another problem with that, after I changed my coding as shown below, it still showing out the error. Inside the coding, there was no any red underline, therefore I can't find out where's the error.
