We're using MS Commerce Server's Microsoft.CommerceServer.Runtime.Profiles.UpmMembershipProvider and sometimes where it gets initialised for the first time after an app restart we get this error:
System.Configuration.ConfigurationErrorsException - System.Web, Object reference not set to an instance of an object. (C:\Inetpub\web.config line 425)
at System.Web.Security.Membership.Initialize()
at System.Web.Security.Membership.get_Provider()
...
Line 425 is the membership provider specification :
<membership defaultProvider="UpmMembershipProvider">
<providers>
<clear />
<add name="UpmMembershipProvider"
applicationName="app"
enablePasswordRetrieval="false"
enablePasswordReset="true"
logonNameProperty="GeneralInfo.logon_name"
requiresQuestionAndAnswer="true"
requiresUniqueEmail="true"
enableCreateDate="true"
enableEmailAddress="true"
enableLastLoginDate="true"
profileDefinition="UserObject"
passwordFormat="Hashed"
maxInvalidPasswordAttempts="5"
passwordAttemptWindow="1"
type="Microsoft.CommerceServer.Runtime.Profiles.UpmMembershipProvider" />
</providers>
</membership>
We took a memory dump and this is what we got:

Anyone come across anything like this before? It doesn't happen every time the app restarts, and it doesn't seem to be on one particular server (site is running on multiple servers behind a load balancer)
I've had the same problem using the SQL Membership Provider with ASP.NET.
It was a configuration problem. Some parameter was set incorrectly.
Maybe this article will help you.
What I can think (at this moment) is that you have a problem with the type attribute, or maybe you didn't copy all of the required dependencies to your Bin..
Good luck
