今天想研究的是如何透過自動化的方式去設定專案的版本號，預期會是與 Git 做掛鉤。

首先，先安裝 GitVersionTask 這個套件：

$ dotnet add package GitVersionTask --version 5.0.1
  Writing /var/folders/hx/lgdjx1l93pq08s35hhwb0py40000gn/T/tmpSIIyRn.tmp

log  : Restore completed in 7.47 sec for /Users/ironman/dotnet-sln/WebProj/WebProj.csproj.

然後在 Repository 根目錄下建立 GitVersion.yml 依照我們要的方式進行設定：

next-version: 1.0
mode: ContinuousDelivery
increment: Inherit
tag-prefix: '[vV]'
source-branches: ['master', 'feature', 'hotfix']
ignore:
  sha: []
  commits-before: 2019-09-29T00:00:00
branches:
  master:
    regex: master$
    mode: ContinuousDelivery
    tag: ''
    increment: Patch
    prevent-increment-of-merged-branch-version: true
    track-merge-target: false
    tracks-release-branches: false
    is-release-branch: true
  release:
    regex: releases/
    mode: ContinuousDelivery
    tag: beta
    increment: Patch
    prevent-increment-of-merged-branch-version: true
    track-merge-target: false
    tracks-release-branches: false
    is-release-branch: true
  feature:
    regex: features/
    mode: ContinuousDeployment
    tag: alpha
    increment: Minor
    prevent-increment-of-merged-branch-version: false
    track-merge-target: false
    tracks-release-branches: false
    is-release-branch: false

先記錄到這邊，預計明天會把設定檔的概念補上來。
