[wix-users] Calling DLL Interfaces from Wix

Managed or Native?

Assuming native, you just need to conform to the signature of a CA.

Ex:
EXPORT UINT __stdcall VJSharp20InstalledCA(MSIHANDLE hInstall)

And then you reference that in your WXS authoring:

<?xml version="1.0" encoding="UTF-8"?>
<Wix xmlns="http://schemas.microsoft.com/wix/2006/wi">
  <Fragment>
    <Condition Message="This application requires Microsoft Visual JSharp 2.0. Please install Microsoft Visual JSharp 2.0 then run this installer again.">
      <![CDATA[Installed OR VJSHARP20]]>
    </Condition>
    <Property Id="VJSHARP20" Secure="yes"/>
    <CustomAction Id="VJSharp20InstalledCA" BinaryKey="Prerequisites" DllEntry="VJSharp20InstalledCA" Return="check" Execute="firstSequence" />
    <InstallUISequence>
      <Custom Action="VJSharp20InstalledCA" After="AppSearch">NOT Installed</Custom>
    </InstallUISequence>
    <InstallExecuteSequence>
      <Custom Action="VJSharp20InstalledCA" After="AppSearch">NOT Installed</Custom>
    </InstallExecuteSequence>
  </Fragment>
  <Fragment>
    <Binary Id="Prerequisites" SourceFile='$(var.SourceFolder)\Bin\Prerequisites.dll' />
  </Fragment>
</Wix>

Note, in this use case my CA does the searches, and assigns a value to the VJSHARP20 property.  This allows me to PropertyRef that property in installers which need it and wix will ensure all the needed bits are included.

I have seen this link. Need one help.
How can I call any dll Interface from Wix? Any pointers?

Thanks. I heard from few folks saying "Difx" will not be supported by Microsoft going forward. So I am trying to write DLL which uses windows APIs to install the driver.

Not sure if this will help, but WiX comes with an extension to install
drivers:
http://wixtoolset.org/documentation/manual/v3/xsd/difxapp/driver.html

But back to your question, you might have to 'wrap' your C DLL with a C++ or C# custom action DLL, i.e. use DllImport

i.e.:
[DllImport("advapi32.dll", EntryPoint = "CloseServiceHandle")]
        public static extern int CloseServiceHandle(IntPtr hScObject);
