Searching/Querying in .NET

- Delegates are good for defining a generic criteria parameter of search method -- no need to hard code criteria in loop of each of multiple search methods (see also Specifications)
- Lambdas obviate need to define named delegate implementations (or methods matching a generic .NET delgate type i.e. Predicate or Func)
- Expression trees to construct lambdas on the fly, allowing construction of criteria at run time

WCF Channel

The Channel is the combination of Data Contract (e.g. ISomething), binding (e.g. HTTP), and endpoint (e.g. URI). It can be used in place of the autogenerated proxy by means of the channel factory.

Control Invoke

Control calls without Invoke (with delegate) from other thread sometimes works but throws exception in Visual Studio

For example modifying the example from http://msdn.microsoft.com/en-US/library/a1hetckb(v=vs.80) to read

POX and WCF Data Services

POX and WCF Data Services implies REST, i.e. access resources via URL (http://weburl/service.svc/Products   retrieves list of products in XML) from which can readily write LINQ queries.

Assign Delegates to Predicates

e.g. Filter property of an ICollectionView is a predicate, so pass it a delegate which is applied to each item (returning true or false based on some criteria)

The RAII Idiom

The essence of the RAII idiom is that the class file encapsulates the management of any finite resource, like the FILE* file handle. It guarantees that the resource will properly be disposed of at function exit. Furthermore, file instances guarantee that a valid log file is available (by throwing an exception if the file could not be opened).
