[asp.net core]project.json（1）
摘要
前面介绍了使用vs2015新建asp.net core web的内容，这篇文章学习下project.json文件的内容。
project.json
原文：https://docs.microsoft.com/zh-cn/dotnet/articles/core/tools/project-json
project.json文件用来定义asp.net core项目的元数据，编译信息和依赖。在本篇文章中，你可以看到你能在project.json中定义的所有属性列表。
Note
.NET Core核心工具将在未来的发布版本中从project.json迁移到MSBuild-based项目。建议仍旧在新的.NET Core项目中使用project.json，但在发布的时候，将会把project转换为MSBuild。
For more information, see the Changes to project.json post on the .NET blog and the Using MSBuild to build .NET Core projects topic.
project.json包括的内容如下

dependencies
类型：Object
定义了项目依赖的包，包名称作为键名，值为版本信息。For more information, see the Dependency resolution article on the NuGet documentation site.
例子：
"dependencies": { "System.Reflection.Metadata": "1.3.0", "Microsoft.Extensions.JsonParser.Sources": { "type": "build", "version": "1.0.0-rc2-20221" }, "Microsoft.Extensions.HashCodeCombiner.Sources": { "type": "build", "version": "1.1.0-alpha1-21456" }, "Microsoft.Extensions.DependencyModel": "1.0.0-*" }
version
Type: String
Specifies the version or version range of the dependency. Use the * wildcard to specify a floating dependency version.
For example:
"dependencies": { "Newtonsoft.Json": { "version": "9.0.1" }}
type
Type: String
Specifies the type of the dependency. It can be one of the following values: default, build or platform. The default value is default.
build is known as a development dependency and is only used for build-time. It means that the package should not be published or added as a dependency to the output .nupkg file. It has the same effect of setting supressParent to all.
platform references the shared SDK. For more information, see the section on "Deploying a framework-dependent deployment with third-party dependencies" on the .NET Core Application Deployment topic.
For example:
"dependencies": { "Microsoft.NETCore.App": { "type": "platform", "version": "1.0.0" } }
target
Type: String
Restricts the dependency to match only a project or a package.
include
Type: String
Includes parts of dependency packages. It can use one or more of the following flags: all, runtime, compile, build, contentFiles, native, analyzers, or none. Multiple flags are defined by a comma-delimited list. For more information, see the Managing dependency package assets specification on the NuGet repo.
For example:
{ "dependencies": { "packageA": { "version": "1.0.0", "include": "runtime" } }}
exclude
Type: String
Excludes parts of dependency packages. It can be one or more of the following flags: all, runtime, compile, build, contentFiles, native, analyzers, or none. Multiple flags are defined by a comma-delimited list. For more information, see the Managing dependency package assets specification on the NuGet repo.
For example:
{ "dependencies": { "packageA": { "version": "1.0.0", "exclude": "contentFiles" } }}
supressParent
Type: String
Defines additional excludes for consumers of the project. It can be one the following flags: all, runtime, compile, build, contentFiles, native, analyzers, or none. For more information, see the Managing dependency package assets specification on the NuGet repo.
{ "dependencies": { "packageA": { "version": "1.0.0", "suppressParent": "compile" } }}
tools
Type: Object
An object that defines package dependencies that are used as tools for the current project, not as references. Packages defined here are available in scripts that run during the build process, but they are not accessible to the code in the project itself. Tools can for example include code generators or post-build tools that perform tasks related to packing.
For example:
{ "tools": { "MyObfuscator": "1.2.4" }}
scripts
Type: Object
An object that defines scripts run during the build process. Each key in this object identifies where in the build the script is run. Each value is either a string with the script to run or an array of strings containing scripts that will run in order. The supported events are:
- precompile
- postcompile
- prepublish
- postpublish
For example:
{ "scripts": { "precompile": "generateCode.cmd", "postcompile": [ "obfuscate.cmd", "removeTempFiles.cmd" ] }}
buildOptions
Type: Object
An object whose properties control various aspects of compilation. The valid properties are listed below. Can also be specified per target framework as described in the frameworks section.
For example:
"buildOptions": { "allowUnsafe": true, "emitEntryPoint": true }
define
Type: String[]
A list of defines such as "DEBUG" or "TRACE" that can be used in conditional compilation in the code.
For example:
{ "buildOptions": { "define": ["TEST", "OTHERCONDITION"] }
nowarn
Type: String[]
A list of warnings to ignore.
For example:
{ "buildOptions": { "nowarn": ["CS0168", "CS0219"] }}
This ignores the warnings The variable ‘var‘ is assigned but its value is never used and The variable ‘var‘ is assigned but its value is never used
additionalArguments
Type: String[]
A list of extra arguments that will be passed to the compiler.
For example:
{ "buildOptions": { "additionalArguments": ["/parallel", "/nostdlib"] }}
warningsAsErrors
Type: Boolean
true to treat warnings as errors; otherwise, false. The default is false.
For example:
{ "buildOptions": { "warningsAsErrors": true }}
allowUnsafe
Type: Boolean
true to allow unsafe code in this project; otherwise, false. The default is false.
For example:
{ "buildOptions": { "allowUnsafe": true }}
emitEntryPoint
Type: Boolean
true to create an executable; false to produce a library. The default is false.
For example:
{ "buildOptions": { "emitEntryPoint": true }}
optimize
Type: Boolean
true to enable the compiler to optimize the code in this project; otherwise, false. The default is false.
For example:
{ "buildOptions": { "optimize": true }}
platform
Type: String
The name of the target platform, such as AnyCpu, x86 or x64.
For example:
{ "buildOptions": { "platform": "x64" }}
languageVersion

For example:
{ "buildOptions": { "languageVersion": "5" }}
keyFile
Type: String
The path for the key file used for signing this assembly.
For example:
{ "buildOptions": { "keyFile": "../keyfile.snk" }}
delaySign
Type: Boolean
true to delay signing; otherwise, false. The default is false.
For example:
{ "buildOptions": { "delaySign": true }}
