Are there any performance issues or caveats with resource (.resx) files? [closed]

 1. Is there a better solution if there is a huge amount of resources? Like 100,000 strings in a .resx file? (Theoretically, I do not actually have this problem)

I've used Alfresco as an alternative content repository on Java projects. RESX files, from a maintaince standpoint (because of encoding issues I guess) can really stink.

 2. Is this a good method for storing the other types of data, such as images, icons, audio files, regular files, etc.?

I've seen it work with images...but that's it. (not sure with other media/files)

 3. Is it a best practice to store your .resx files in a stand-alone project for easier updates/compiling?

I don't, but you can edit a resx file on a live site and then edit will go through, I believe. Certainly that's the way it works in development (except for the global resx, I think)

 4. Are there any other issues that you have run into when using .resx files?

Besides being really annoying to maintain, and the fact that visual studio doesn't provide the neatest tools for working with them...no.

I recently used a .resx file with 5 million strings (normal length, like this sentence), compiled in different DLLS about 1 GB in size. It still works fine in an Azure web project.

The load time is unknown, maybe few seconds or so, since it always can heat up in stages, I never noticed it.

We have been using resource files on a relatively large .NET Windows Forms application (over 500 various forms, approximately 20 resource strings per form) and we've had no performance issues regarding resources from .resx files.We have used Babylon.NET as a tool for managing translations (has a free version just for translators). You did not specify if your project will be web or desktop application. One functionality that resource files offers for desktop applications is the ability to also localize control positions and size which IMHO is not possible using other tools (unless you are using something like DevExpress layout control which has automatic sizing).
