Difference between Visual Studio Redistributable and Visual Studio SP1

Are ther开发者_运维技巧e many redistributable packages? If so, how do I know which package to download?

You will need the redistributables for any of the environments you develop in. Note the "full" versions for the .net Frameworks contain both 32-bit and 64-bit versions.

The visual studio SP1 redistributable fixes issues (bugs) in visual studio and updates the security
-> Use this if you have VS and want to update

The visual studio redistributable puts updated versions of assemblies, packages and dlls on your machine

If using InstallShield, you should update your MSMs to point to the new Visual C++ libraries.
