Hosting ASP websites and WCF services on GoDaddy

Recently I bought GoDaddy hosting for few purposes. Firstly, I want to integrate my web experiments into sunauskas.com domain and to keep this blog running on WordPress. Secondly, I am developing small project based on ASP.NET + WCF + DB (NHibernate ORM), so multiple users testing will be needed in near future.

I had almost no problems publishing ASP MVC website and WCF service. To make it clear, firstly I published files locally and after that just copied them to the host. Because GoDaddy at the moment doesn’t support publishing to the host directly (???). After that I came to some GoDaddy and .NET configuration issues.

Most issues occur because of the security configuration. This was that case. Locally my application is running on full trust. So I needed to be like that also on the hosting.

This is security exception which I was getting:

Description: The application attempted to perform an operation not allowed by the security policy. ┬áTo grant this application the required permission please contact your system administrator or change the application’s trust level in the configuration file.

Exception Details: System.Security.SecurityException: Request for the permission of type ‘System.Security.Permissions.ReflectionPermission, mscorlib, Version=, Culture=neutral, PublicKeyToken=b77a5c561934e089’ failed.

Here is my ASP.NET web site and WCF service hosting configuration with full trust.

<trust level=”Full” />

I hope this trick will save you few hours. It can be that your applications don’t require full trust and you can try to set any other trust level.
