Help getting Opserver deployed

[HBollah]

I must be a bit of a thicko here and not that familiar with VS. I have downloaded the code, opened the solution in VS, made changes to the security and added some SQL servers.

If I run this in debug mode, it all opens up fine and can browse the servers, databases etc.. But when I go to deploy to IIS (on my laptop for testing deployment) it seems half the files are missing and the site doesn't load. No problem, I'll just rebuild the solution and copy to the IIS folder, but when I browse the localhost url , I'm getting a http 500 error and nothing on the page to help identify what the issue is, even though the detailed information is on.

Any pointers would be greatly appreciated.

Thanks.

Well, not sure what the issue with IIS is on my laptop, but copied the files to a server and it is working fine there, so please feel free to close this non issue :-)

You could always check the Event Viewer for warnings/errors from ASP.NET. :)

I know this is an old post, but I have the same issue deploying the application to a localhost. Any ideas would be greatly appreciated.

I am running into the same problem. I am not an expert, but with IIS Express, I can get it running, but when deploying to IIS, I get HTTP 500.

Anyone would be able to give me some hints on where to check?

[HBollah]

The difference I found was when you have the files added into Visual Studio you need to complete a build of the project, then deploy the files to the server.

So.. I have deployed the website and still can't get it wrong.. I might be missing something really simple.

This is what looks like in the Server

And under config I have included the config files.

and this what I have in the advanced settings.

Having the same issue here. Looks like I will have to give up on OpServer. After deployment all I get its Error 500. :-( Did you ever get it working Marcos?

If you folks turn on friendly Error Messages, what do you get?

Add these tags in the appropriate places to your web.config:

<configuration>
    <system.webServer>
        <httpErrors errorMode="Detailed" />
    </system.webServer>
    <system.web>
        <customErrors mode="Off" />
        <compilation debug="true" />
    </system.web>
</configuration>

I made that change and refreshed and this is what I get now.

I am taking a look at the following article now to see if that might help.

I found that I did not have Windows Authentication installed in IIS. One that was installed I now get the following:

Fittingly, this SO post has some suggestions as to what the problem may be, and how to fix it.
Aside from that, you could put some Exception Handling code around the GetTypes call, which is where the exception is occurring.

I finally got it working after experiencing the HTML 500 error for few hours.

Make sure you have on ISS (Add Features):

• ASP.NET 4.5
• .NET Extensibility 4.5
• Windows authentication

If you can get the deployment working within Visual studios on IIS express then it's most likely to do ASP compiling issues (with production IIS).
