Sample code using the app.config:
ContextFactory contextFactory = ContextFactory.Instance;
IServiceContext serviceContext = contextFactory.NewContext();
app.config section I’d like to set in code instead of having the API read it directly.
<Emc.Documentum>
<FS>
<ConfigObject type="Emc.Documentum.FS.Runtime.Impl.Configuration.ConfigObject, Emc.Documentum.FS.Runtime"
defaultModuleName="core" registryProviderModuleName="core" requireSignedUcfJars="true">
<ModuleInfo name="core" protocol="http" host="documentum.current.dev" port="9080" contextRoot="services"/>
<ModuleInfo name="search" protocol="http" host="documentum.current.dev" port="9080" contextRoot="services"/>
<ModuleInfo name="bpm" protocol="http" host="documentum.current.dev" port="9080" contextRoot="services"/>
<ModuleInfo name="collaboration" protocol="http" host="documentum.current.dev" port="9080" contextRoot="services" />
</ConfigObject>
</FS>
</Emc.Documentum>
