GAC Assembly naming (ASP.Net 2 + IIS7 + Windows Vista Home Premium)

Question

I have a membership provider assembly that I wish to add to IIS7. I was going to leave this in the App_Code file for the web app, but IIS7 has asked me to provide a strong name assembly, which I have. Now I get this when trying to acccess ASP.Net Users in IIS

The assembly name or codebase was invalid. Exception from HRESULT 0x80131047

The machine.config contains

<providers>
    <add 
     name="AspNetSqlMembershipProvider" 
     type="System.Web.Security.SqlMembershipProvider, 
       System.Web, 
       Version=2.0.0.0, 
       Culture=neutral, 
       PublicKeyToken=b03f5f7f11d50a3a" 
     connectionStringName="LocalSqlServer" 
     enablePasswordRetrieval="false" 
     enablePasswordReset="true" 
     requiresQuestionAndAnswer="true" applicationName="/" 
     requiresUniqueEmail="false" 
     passwordFormat="Hashed" 
     maxInvalidPasswordAttempts="5" 
     minRequiredPasswordLength="7" 
     minRequiredNonalphanumericCharacters="1" 
     passwordAttemptWindow="10" 
     passwordStrengthRegularExpression=""/>

    <add 
     name="AspNetReadOnlyXmlMembershipProvider" 
     type="AspNetReadOnlyXmlMembershipProvider, 
       Version=1.0.0.0, 
       Culture=neutral, 
       PublicKeyToken=63c37b63efdc6bcc, 
       processorArchitecture=x86"/> 

</providers>

I am wondering if this has anything to do with using Visual Studio 2008 as the gacutil shows .Net Framework version 3.5. The code itself looks fine.

Answer 1

Is it necessary to change the version of the assembly I am trying to add to GAC each time I make a change to the source? Even if I remove the old assembly and add the new assembly using the gacutil?
