Set ASP.Net version using WiX

Question

I am creating an installer for an ASP.Net website using WiX. How do you set the ASP.Net version in IIS using WiX?

Answer 1

We use this:

First determine the .Net framework root directory from the registry:

<Property Id="FRAMEWORKROOT">
  <RegistrySearch Id="FrameworkRootDir" Root="HKLM"
                Key="SOFTWARE\Microsoft\.NETFramework" 
                Type="directory" Name="InstallRoot" />
</Property>

Then, inside the component that installs your website in IIS:

<!-- Create and configure the virtual directory and application. -->
<Component Id='WebVirtualDirComponent' Guid='{GUID}' Permanent='no'>
  <iis:WebVirtualDir Id='WebVirtualDir' Alias='YourAlias' Directory='InstallDir' WebSite='DefaultWebSite'  DirProperties='DirProperties'>
    <iis:WebApplication Id='WebApplication' Name='YourAppName' WebAppPool='AppPool'>
      <!-- Required to run the application under the .net 2.0 framework -->
      <iis:WebApplicationExtension Extension="config" CheckPath="yes" Script="yes"
                    Executable="[FRAMEWORKROOT]v2.0.50727\aspnet_isapi.dll" Verbs="GET,HEAD,POST" />
      <iis:WebApplicationExtension Extension="resx" CheckPath="yes" Script="yes"
                    Executable="[FRAMEWORKROOT]v2.0.50727\aspnet_isapi.dll" Verbs="GET,HEAD,POST" />
      <iis:WebApplicationExtension Extension="svc" CheckPath="no" Script="yes"
                    Executable="[FRAMEWORKROOT]v2.0.50727\aspnet_isapi.dll" Verbs="GET,HEAD,POST" />
    </iis:WebApplication>
  </iis:WebVirtualDir>
</Component>

For an x64 installer (THIS IS IMPORTANT) Add Win64='yes' to the registry search, because the 32 bits environment on a 64 bits machine has a different registry hive (and a different frameworkroot)

<RegistrySearch Id="FrameworkRootDir" Root="HKLM"
        Key="SOFTWARE\Microsoft\.NETFramework" 
        Type="directory" 
        Name="InstallRoot" Win64='yes' />
