Enterprise Library is Microsoft's next generation of Application Blocks. It's a free, integrated suite of common architectural components that your project probably needs. It has several good perks:
- Includes all source code
- An auto-config tool to handle the Xml config files.
- 38 projects of well written code - i.e. a good example to learn from
- Full documentation
- A huge community supporting it.
You can download it here. Be sure to check the official blogs:
When I first was playing around with it, I had trouble with creating strong names and config files.
Configuration Tips
1. A single application can have multiple physical config files:
- CachingQuickStart.exe.config (app)
- cachingConfiguration.config (other block)
- dataconfiguration.config (other block)
Furthermore, you'll need to make sure that the correct file is copied to the app's bin. Merely rebuilding or using EntLib's config tool doesn't copy all configs.
2 - For the data access block config, you'll need to set both the connection string as well as the individual params. Config looks like:
<connectionString name="Data Source=localhost;Initial Catalog=Caching;Integrated Security=SSPI;">
<parameters>
<parameter name="Database" value="Caching" isSensitive="false" />
<parameter name="Integrated Security" value="True" isSensitive="false" />
<parameter name="Server" value="localhost" isSensitive="false" />
</parameters>
</connectionString>

3 - For the Caching Block's Data Provider:
- "PartitionName" does not correspond to actual database partitions, but rather a value in the Caching.CachData.PartitionName column. This means that you don't need to create a DB partition for the DB cache to work.
- Make sure that you run the script to create the Caching DB ('Caching').
- Make sure that user has access to the 'Caching' database, and can insert into the CacheData table. Merely running the create script doesn't provide access to custom users.
4 - For the Caching Block's Isolated Storage, this uses System.IO.IsolatedStorage. You do not provide a physical file path name. Partition Name is a folder name like "MyApp".
I'll discuss Strong Names in my next post.
