Warnings for each table in dataSet

[Tenzen]

I get warnings for each table (from Access database) in my dll plugin project:

Type library exporter warning processing '[PluginName].DataSet+[TableName]DataTable, [PluginName]'. Warning: Type library exporter encountered a type that derives from a generic class and is not marked as [ClassInterface(ClassInterfaceType.None)]. Class interfaces cannot be exposed for such types. Consider marking the type with [ClassInterface(ClassInterfaceType.None)] and exposing an explicit interface as the default interface to COM using the ComDefaultInterface attribute.

How to fix it? Could it be reason why my COM+ assembly is not registering with Wix installer?

Have you rpovided an explicitly defined COM interface or are you just getting Visual Studio to try and guess at what parts of everything are to be exposed to COM?

I always write an explicit interface, personally..

I'm not too familiar with COM... I was able to register my dll on build and with regasm in installer - CustomAction in Wix. But this CustomAction works only when I run msi file as administrator and I want now to do it better.

How to define COM interface?


Here I wrote about my Wix problem: COM+ Applications with DataBase error on install

When I did it in a c# app I made:

An interface of everything I wanted to see in com
A class that implements the interface
The class is marked ClassInterface(ClassInterfaceType.None)
The assemby is com visible

And that was it really, i think.. When compiled and regasmed it showed up as something I could add to e.g. VBA
