Well after spending half an hour looking on the net on how to disable WarningAsError on a WEBSITE project, everyone kept saying the same thing – edit the project settings – WELL A WEBSITE PROJECT DOSENT HAVE PROJECT SETTINGS!

Anyway, here is the solution, you need to edit your web.config :

<system.codedom>
 <compilers>
 <compiler language="c#;cs;csharp" extension=".cs" type="Microsoft.CSharp.CSharpCodeProvider,System, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" warningLevel="3" compilerOptions="/d:DEBUG;TRACE">
 </compiler>
 </compilers>
</system.codedom>

Should turn into the following:

<system.codedom>
 <compilers>
 <compiler language="c#;cs;csharp" extension=".cs" type="Microsoft.CSharp.CSharpCodeProvider,System, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" warningLevel="3" compilerOptions="/d:DEBUG;TRACE">
 <providerOption name="WarnAsError" value="false"/>
 </compiler>
 </compilers>
</system.codedom>

The line you want in question is:

<providerOption name="WarnAsError" value="false"/>

And this baby will make it work! Enjoy!
