.NET Assembly Definition
Building block of .NET applications– Logical unit of functionality (a DLL in physical terms)
– Implementation independent
– Contains code – Microsoft Intermediate Language (MSIL) – executed by Common Language Runtime (CLR)
Imposes boundaries for contexts of – Security
– Type
– Reference scope
– Versioning
– Deployment
Implications for PowerBuilder developers– Immediate reuse of existing code in .NET architectures
– “Full citizenship” in .NET application development circles

PowerBuilder .NET Assemblies
Design the business logic– PowerBuilder 11 supports the deployment of non-visual objects
(Custom Class User Objects) as .NET assemblies
– Existing NVOs can be leveraged by creating a new .NET Assembly Target that references the original target
– Implement methods in PowerScript as you would for a traditional PowerBuilder application
– Only a few caveats• Proprietary PowerBuilder types (e.g., datastore, transaction,
etc.) cannot be used in public method signatures• Instance variables are not exposed – define your own
getter/setter methods• Some PowerScript constructs are not supported in .NET

functions) is supported

PowerBuilder .NET Assemblies
Define the deployment properties (Post-build)– Any command recognizable by operating system
– Sample uses• Invoke .NET obfuscator tool• Copy output to staging area• Send page/e-mail indicating build is complete
Different actions depending on build typeDifferent actions depending on build type

PowerBuilder .NET Assemblies
Define the deployment properties (Run)– Specify application used to invoke assembly
• “Running Man”• Debugger
“Client” application path“Client” application path

PowerBuilder .NET Assemblies
Debug project settings– Specify test application on Run tab
– Specify “Debug” as build type

PowerBuilder .NET Assemblies
Assembly debugging sequence
1. Set breakpoints in PowerBuilder script view
2. Launch “Run” application using Debug option
3. Execution pauses when client application invokes the PowerBuilder assembly and reaches a defined breakpoint
4. At this point, most “classic PowerBuilder” debugging options are available
HELP! My breakpoints aren’t being triggered!
Ensure the correct .PDB file, generated during deployment, is available (typically placed in same
directory as assembly)
