Question

考虑以下.wxs

<Feature Id="Prod.Full" Level="1" Title="!(loc.FeatureAllFiles)">
  <Condition Level="0"><![CDATA[NOT((MYPRODINSTALLATIONTYPE ~= "FULL") OR (MYPRODINSTALLATIONTYPE ~=""))]]></Condition>
  <FeatureGroupRef Id="FeatureGroup.FullA"/>
  <FeatureGroupRef Id="FeatureGroup.FullB"/>
  <FeatureGroupRef Id="FeatureGroup.FullC"/>
</Feature>

<Feature Id="Prod.AddCompFree" Level="1" Title="!(loc.FeatureAdditionalFiles)">
  <Condition Level="0"><![CDATA[NOT((MYPRODINSTALLATIONTYPE ~= "FREE") OR (MYPRODINSTALLATIONTYPE ~=""))]]></Condition>
  <FeatureGroupRef Id="FeatureGroup.FullB"/>
</Feature>

想象一下，我用MYPRODINSTALLATIONTYPE = FULL运行msi

安装是否包含所有三个功能组（FeatureGroup.FullA，＆＃34; FeatureGroup.FullB，＆＃34; FeatureGroup.FullC）

或

将在安装中删除FeatureGroup.FullB吗？

Answer 1

简答：FeatureGroup.FullB将在安装中删除

长答案：运行CostInitialize / CostFinalize操作时，将按顺序处理Condition表：top - ＆gt;底部。

首先处理此行，条件为FALSE（没有功能设置为InstallLevel = 0）

<Feature Id="Prod.Full" Level="1" Title="!(loc.FeatureAllFiles)">
  <Condition Level="0"><![CDATA[NOT((MYPRODINSTALLATIONTYPE ~= "FULL") OR (MYPRODINSTALLATIONTYPE ~=""))]]></Condition>
  <FeatureGroupRef Id="FeatureGroup.FullA"/>
  <FeatureGroupRef Id="FeatureGroup.FullB"/>
  <FeatureGroupRef Id="FeatureGroup.FullC"/>
</Feature>

第二行处理此行，条件为TRUE（FeatureGroup.FullB具有InstallLevel = 0）

<Feature Id="Prod.AddCompFree" Level="1" Title="!(loc.FeatureAdditionalFiles)">
  <Condition Level="0"><![CDATA[NOT MYPRODINSTALLATIONTYPE ~= "FREE"]]></Condition>
  <FeatureGroupRef Id="FeatureGroup.FullB"/>
</Feature>

Wix：在具有不同条件的不同功能下添加相同的功能组ID会删除已添加的功能吗？
