I have built my new website in Visual Studio 2010 (C# - ASP.NET 4). Back when I started the project, I selected "ASP.NET Web Application" in the 'New Project' window.
I have also just gotten a new web host / domain, where I will put my website. And yes, the server does support ASP.NET 4.
I wanted to make a small "test project", to see if my final website would work as well. Problem is, I can't even make this small test project work on the server.
If you have Visual Studio installed, you can follow these steps if you like, but I will write what happens too:
- New project -> "ASP.NET Web Application"
- Just calling it "WebApplication1"
- Don't change any code, just go to Build -> Build Solution.
- Project -> WebApplication1 Properties...
- Under Package/Publish Web, I select Configuration: Release (it is to my understanding that this must be selected when publishing to a web server - not sure if I'm wrong?)
- Put this line in Web.config:
<customErrors mode="Off"/> - Build -> Rebuild Solution
- Build -> Publish WebApplication1
- Choose 'File System' and put target as 'C:\CompiledSite'. I tried to use the FTP option, but then it said that some FrontPage Extension wasn't installed at the server. I don't know, I didn't ask for any FrontPage here. So I try this on the C-drive instead.
- Copy all files from the 'CompiledSite' folder and onto my test folder on my domain.
I get this error:

In the file "Web.config".
Please, I have no idea how to fix this and please let me know any info on how to get my test site up and running.
