Chris,

>I started up an old project that used to work and it recompiled w/ no errors. Now I'm getting the following error at runtime:
>
>Compiler Error Message: CS0011: Referenced class 'OakLeaf.MM.Main.Web.UI.WebControls.mmButton' has base class or interface 'OakLeaf.MM.Main.Security.ImmSecurityBase' defined in an assembly that is not referenced. You must add a reference to assembly 'Mere Mortals Framework Interfaces'.

In the version 1.1 What's New Guide there were instructions for upgrading projects to MM .NET 1.1:

Open your Web Form application’s web.config file and change the <compilation> element from:

<compilation defaultLanguage="c#" debug="true" />

To the following:

<compilation defaultLanguage="c#" debug="true" >
	<assemblies>
		<add assembly="Mere Mortals Framework Interfaces, Version=1.1.1118.20862, Culture=neutral, PublicKeyToken=2312fefb461dbb0e" />
		<add assembly="Mere Mortals Framework Web Forms, Version=1.1.1158.18447, Culture=neutral, PublicKeyToken=a16649d902b008d4" />
	</assemblies>
</compilation>

I think applying this change will fix the problem.

Regards,
