.NETFrameworkSDK 和 TargetingPack 之间有什么区别

小开

最佳答案

The .NET Framework SDK, is a software development kit (SDK) from Microsoft.

It is required to develop applications for the .NET Framework and it contains:

documentation
header files
libraries
Samples and tools.

.NET Framework SDK is dedicated to developing applications for .NET Framework. When installing visual studio, this is enough.

Targeting pack is needed when You are targeting a particular .NET framework which is different from your currently installed .NET framework.

In the case of the targeting pack, let's say you build your application using .NET 4.7 but the client has .NET 4.5. For this type of scenario you can target the client's version even though you are using a higher version.

Here you can see how to target a particular .NET framework.

Here is the difference, according to

learn.microsoft.com

A targeting pack: lets your app target a specific version of the .NET Framework when developing in Visual Studio and some other development environments.

A developer pack: includes a specific version of the .NET Framework and its accompanying SDK along with its corresponding targeting pack.

In other words, for example: SDK 4.7.1 includes .NetFramework 4.7.1 and target pack 4.7.1. But if you want to target .Net Framework 4.6, you need to install the target pack 4.6

Wondered the same!. It looks like targeting packs are mainly to install reference assemblies(assemblies with no implementation) for that particular .net version, to just let IDE/Build tools compile.

I couldn't find much information on what exactly SDK comprises of, but I think its just bunch of tools plus some other stuff(the download size is consistently ~30mb across all .net versions)

some useful links -

Was the "Developer pack" originally called SDK?

Can I use Visual Studio 2015 to target .net framework 4.7?

On a side note: Developer pack = SDK + Targeting pack.
