How to do Membership in ASP.NET MVC?

I want to do membership in ASP.NET MVC. I am not talking about the one that comes with an ASP.NET MVC. project.

I am talking about a database that I have my own custom tables and the aspnet.db tables combined.

I know how to do this in WebForms, and I have combined my tables with the membership stuff, but when I try to add my custom role providers to my web.config like I would in WebForms nothing works.

What is different?

It is so weird. I went back a couple versions in my SVN to a version and added my connection string and changed a couple things around and it works just fine using my database.

When I upload it to Subversion, grab that copy from Subversion 2 seconds later, and load up the solution, it does not work again.

This is the error I am getting:

System.Web.HttpException was unhandled by user code
  Message="Validation of viewstate MAC failed. If this application is hosted by a Web Farm or cluster, ensure that <machineKey> configuration specifies the same validationKey and validation algorithm. AutoGenerate cannot be used in a cluster."

Solution

  • Disabling the enableViewStateMac setting in the web.config should get rid of that "Validation of viewstate MAC failed" error.

    Set it like this....

    <system.web>
  <pages enableViewStateMac="false" />
</system.web>

    Hope that helps. Good luck.
