[Mono-dev] Using assembly in GAC fails but runs okay in same path as executable

[Daniel Morgan]

I will answer myself.

Using app.config for an assembly in Microsoft .net 1.1 GAC requires the 
fully-qualified assembly name while mono 1.1 does not.

Modifing the section to include the fully-qualified name works.

<section name="providers" 
type="Mono.Data.ProviderSectionHandler,Mono.Data, Version=1.0.5000.0, 
Culture=neutral, PublicKeyToken=0738eb9f132ed756" />
