5 days, 9 hours ago professionalaspnet.com — Dealing with Null values (nothing in VB.NET) is a common problem for programmers of any stripe. Null dates stored in the database seem to be a common issue developers experience when they start dealing with null values. Null values in the database for a value type poses a problem in the application. The .NET framework provides Nullable Types, a Coalesce operator in C# and If in VB.NET that can help the situation. read more...

This is currently used in our build environment and in subversion hooks to analyze the output in pre-commit hooks to determine if the changes are allowed to the repository.

SyncLock requires that all CPU instructions be cleared from the registers so that thread synchronization can be performed safely and it also requires a lot of management by the .NET threading libraries.
In certain situation where multiple threads are running, you may require that just a single thread execute a piece of code at any one time. I've used this in situations where multiple threads are there for performance reasons but only 1 thread at a time should say clear down/refresh cache entries, but any of those threads could do the work.
