Deploying SQL CE 4 to IIS 7 - Special Permissions Needed?

Question

I have an ASP.NET 4 site that uses the new SQL CE 4 CTP. The site works fine locally (IIS 7.5 on Win7) and fine in Server 2003/IIS 6. It fails when deploying to IIS 7 on Ser

Answer 1

I'm currently running a web server with a fresh copy of Windows Server 2008 R2 with SQL CE 4.0 installed into GAC.

I had a similar problem but it was more along the lines of:

"The underlying provider failed on Open" in the event logs. I'd try everything as well as looked up everything on SO and google. Tried both suggestions here and finally started making some headway.

In addition to adding read/write permissions (Thanks ErikEJ) was a step in the right direction, but which user exactly to grant those permissions to was the hard task (Thanks Robbo). Unfortunately, this didn't help me completely and after labouring back and forth with user and permissions the the end result was that I needed the following two permissions before it worked:

IUSR IIS_IUSRS

Both required read/write permissions to the application folder.

Hope this helps out along with the provided answer above - Sure helped me out.
