从现有的 Azure Web 应用程序创建 Visual Studio 2019 项目

Question

I have a v7 Umbraco instance as a Web App on Azure but the machine the dev copy was on has been decommissioned and I need now to recreate the dev site in Visual Studio 2019, ideally cloning it from the live site in some way. I have created an empty project and, using the cloud explorer, downloaded the files from the app, but I am unclear whether I just copy them directly into the solution folder or into their own subfolder of the solution folder or whether simply copying them in will do the trick anyway as there's still the database to consider as well. I'm afraid I haven't used Visual Studio since creating this site three or so years ago and I seem to have forgotten most of what I did then anyway, so any help wpuld be greatly appreciated. The only advice I coud find via google was for older versions of VS and so not much help.

Answer 1

Recreating the original project from the live site is probably not going to be possible. It depends how and what you deployed to the live site.

It sounds like what you have is a working live site, but have lost access to the original source code. You should be able to copy the site and get it working elsewhere, but you're probably going to struggle to recreate the original development environment and amend the compiled elements of the website without access to the source code.

The Umbraco.com website has some great documentation on getting started and setting up Umbraco. Umbraco TV is great for getting up to speed quickly too. This should help explain the project structure. I suggest you create a blank Umbraco install to familiarise yourself with how Umbraco works(I wrote a post explaining how to do this with MS VS2015 here ).

A typical deployment, using MS WebDeploy or FTP from Visual Studio, wouldn't deploy the project files or source-code for the compiled (.cs) elements of the website, these are usually kept as development files and checked in to source control.The live site probably only has the compiled versions of these file in the bin folder. The good news is the Razor template and view files(.cshtml) should be on the server.

However, if everything was uploaded (it happens) then you may have a chance, in which case you can download the files, potentially open the project and try to run the project locally on the development machine. There's no reason why you can't install an older version of MS Visual Studio alongside 2019 if there's an issue with that version. Although, I suspect this isn't an option since you felt the need to create a new empty project. If this is the case you might be able to add any project files to the the new empty project and attempt to recreate the project that way.

Regarding the database. You're going to need a copy or backup installed on a Microsoft SQL Server (unless you used MS SQL CE which is file based). You should be able to download a .bak file from the server if you're using Plesk or connect remotely using MS Management Studio if not, it depends on the host (Azure will allow access via MS Management Studio). Umbraco will need the connection string configured in it's web.config, the one you downloaded may be trying to connect to the live server so be careful.

Long shot ideas:

• If you're really desperate you might be able to reverse engineer some of your compiled .dll using a tool like ILASM.exe but it's not going to be easy;
• Perhaps you could reference the .dll in a the new project and it will all work auto-magically?! but I doubt this will work as there will be two application starting points and you'll probably get a runtime exception.
