moving VB.Net DLL for Excel to a cloud service on Azure

Question

I've got a DLL written in VB.NET that provides Excel plugin capabilities. I'd like to move it into a cloud service. As far as I can tell, there's no way to use that DLL in the web-based version of Excel, so...

Is there a way to host the DLL online and just send/receive data to the DLL pretending to be Excel?

Answer 1

• Create VB.Net Class Library, build and run the app
• Create web Application (your required framework)
• Add the Existing VB.Net Class Library to the newly created Web App or add the class library dll (all the required dll's ) to the new web app.
• All the dlls will be available in the bin folder
• When you deploy your web App to Azure by default all the folder/ dll's will be deployed to Azure

• Or else you can directly upload the required dll files to KUDU Console

UPLOADING DLLS TO REFERENCE THEM FROM AZURE WEB APP

• Open App Services in your Azure => Click your Web App => Click “Advanced tools (Kudu)” – will open in a new tab:

• Then “Tools” –> “ZIP Push Deploy”;

• Then click the folder with your Web App name and go to the “bin” folder;

• Drag&drop the dll’s you want to make reference to in your Azure Web App:
  

• Now you can reference your dll's from your Azure Web App
