我想验证.NET Framework 4.0和4.5应该在安装之前安装在服务器上。因此，我使用了以下代码段，但是我不知道4.5的验证，没有列在链接
Reference中
<PropertyRef Id="NETFRAMEWORK40FULL"/>
<Condition Message='This setup requires Microsoft .NET Framework 4.0 Full package or greater needs to be installed for this installation to continue.'>
<![CDATA[Installed OR NETFRAMEWORK40FULL]]>
</Condition>
NETFRAMEWORK45属性可以与NETFRAMEWORK40FULL相同。请注意，.NET Framework v4.5没有“客户端”或“完整”框架。只有一个。所以下面的代码应该做你想要的：
<PropertyRef Id="NETFRAMEWORK40FULL"/> <PropertyRef Id="NETFRAMEWORK45"/> <Condition Message='This setup requires Microsoft .NET Framework 4.0 Full package or greater needs to be installed for this installation to continue.'> <![CDATA[Installed OR NETFRAMEWORK40FULL]]> </Condition> <Condition Message='This setup requires Microsoft .NET Framework 4.5 package or greater needs to be installed for this installation to continue.'> <![CDATA[Installed OR NETFRAMEWORK45]]> </Condition>
请注意，.NET Framework v4.5是.NET Framework 4.0的就地升级，因此检查两者都可能会导致您无法满足这两种情况。您可能只想检查是否已安装.NET Framework v4.0或.NET Framework v4.5。这种情况看起来更像：
<Condition Message='This setup requires Microsoft .NET Framework 4.0 Full or 4.5 package or greater needs to be installed for this installation to continue.'> <![CDATA[Installed OR NETFRAMEWORK40FULL OR NETFRAMEWORK45]]> </Condition>
