Azure COM Objects

问题:

I am trying to move a website I am hosting on a server with IIS over to an Azure web site. I'm using a COM object but I'm not sure if I can register this? I found some posts talking about uploading the dll and registering it on start up but the article seems to be missing. Is this possible?

I had this exact problem registering legacy COM Components on Azure. I documented my methodology here:

AspPDF and AspJPEG on Windows Azure

Igorek is correct, you will need to use a Web Role to achieve this. The solution above is based on a single Web Role with a startup script to run regsvr32 as a startup task.

To summarise, there are essentially two parts to achieving this. First create a batch file to run the regsvr32 command:

chcp 1252>NUL
regsvr32 /s .\library\my-com-class.dll
exit /b 0

Then define a startup task in your ServiceDefinition.csdef file:

<Startup>
<Task commandLine="mybatchfile.cmd" executionContext="elevated" taskType="simple" />
</Startup>

This will trigger the command file to run on deployment.

You cannot register a COM object within an Azure Website. You will need to upgrade to Web Roles in order to do this. Registration of com object can happen during the startup scripts then.
