The authoring of NuGet packages quite often include `build` folders, and when this is .gitignore'd it's very often the source of bugs in files that don't get checked in.

I've never seen a Visual Studio project that builds to a `build` folder (`bin` is the default name). As this is a Visual Studio template file, and we have real projects that include `build` folders that include source code, I recommend we remove suppression of this folder.

Recent versions of FAKE uses a cache folder containing a compiled version of all scripts named .fake that should never be commited to git.

Added ignore as recomended in http://fsprojects.github.io/Paket/getting-started.html

Ignoring directory "efc" and "rfc" created by the Windows Azure Emulator

Directory before starting emulator the first time:

In Windows Phone 8 development each profiler session generates a new .sap file, which is automatically added to the root of the project. This is an XML manifest describing the detailed profiler logs created in the PerfLogs folder.

There are use cases where you have gulp/grunt tasks that create the static files of a project from bower_components, images, scripts folders.

As discussed in #1505

As of Visual Studio 2015 CTP5 the Roslyn cache and suo files are stored in a .vs/ directory.

Ignoring *.cache as well as *.Cache

Revert "adding entry for ignoring <solutionname>.sln.ide folder which contains visual studio 2015 solution specific cache data"

This reverts commit b07a0904.

adding entry for ignoring <solutionname>.sln.ide folder which contains visual studio 2015 solution specific cache data

I haven't found good documentation for this file online, but it is a user based file that should be ignored.

This files is generated by Visual Studio 2013 and should be ignored.

user passwords are stored in *.user files so it is only database connection strings that are not protected.

https://github.com/github/gitignore/commit/08def965cd1c0241a7cffbe7c26a74b3cab61243 incorrect states that commenting *.pubxml will keep your passwords hidden when it will actually do the opposite. This clarifies what commenting *.pubxml does and warns you of the dangers.
