Supporting multiple custom RoleProvider versions

[Chris Cichocki]

All of the configurations I've seen for the role provider specify a simple
(weak) type name. What if I had multiple custom role provider
implementations in the GAC and wanted to specify an exact version? I've
tried putting the fully qualified (strong) name into the "type" attribute but
it says it can't load the type. Am I missing something or is a simple type
name all that can be used?

Thanks
Chris

Hello Chris,

As for the the "roleManager" providers, ASP.NET 2.0 does support multiple
providers configured in appilcation web.config file. And you can point to
the RoleProvider type in both GAC or application's private bin dir. And
for private bin assembly, since they're not strong-named, you can simply
supply the main assembly name(do not need version, culture and public key
token info...). For assembly in GAC, you need to supply all the four parts
(assembly name, version, culture, pubic key token ) for it. For example:


====================
<roleManager defaultProvider="NewAspNetSqlRoleProvider">
<providers>
<add name="NewAspNetSqlRoleProvider"
connectionStringName="LocalSqlServer"
applicationName="MyApplication"
type="System.Web.Security.SqlRoleProvider, System.Web, Version=2.0.0.0,
Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" />

<add name="customprovider" .....................
type="MyProviders.CustomRoleProvider,
myproviders" />

</providers>
</roleManager>

====================

Also, if you're not sure about the exact synatx of the
assemblyQualifiedname of your provider type(in GAC) ,you can use the
following code to print it out:
===================
protected void Page_Load(object sender, EventArgs e)
{
Response.Write("<br/>FullTypeName: " +
typeof(SqlRoleProvider).AssemblyQualifiedName);
}
=====================

In addition, if the problem is that the runtime failed to load the correct
assembly, you can use the framework tool(Assembly binding viewer) to trace
the load process of any assembly loading failure.

Please feel free to let me know if the above helps or if you meet any
further problems on this.

Hi Gaurav,

Thanks for your reply.

Yes, no matter how many providers we configured in our application, only
one default provider is used. However, this is the case if we use the
default provider (those special class rather than directly reference the
provider instance) in our application code. Actually, we can
programmticaly get the reference to each provider we've configured in
application web.config and use them in our application, e.g.

================

Membership.Providers["customProvider1"].ValidateUsertxtUsername.Text,
txtPassword.Text);

===================
