If you enable the "Use FIPS compliant algorithms for encryption, hashing, and signing" security policy option in Windows, attempting to use many of the cryptographic classes in the .NET Framework will result in an InvalidOperationException. By default, ASP.NET uses AES to encrypt the ViewState blob, so it fails. You can work around this ...

Importance of unit testing my Views when using the MVVM pattern?
When using the MVVM pattern to structure your WPF application you should get all your business logic out of the View and code-behind files. Doing it properly the View itself will be a simple facade with Data Bindings and Command Bindings to the ViewModel classes - which is where the magic happens. One key benefit from structuring your a...
Suggestions for a 3rd party .net datagrid control - ideally free?
I've been looking for a databound control to show some data to the user, who needs to be able to filter and group the output.

Example of 'volatile' preventing a compiler optimization in C#?
From what I understand, the 'volatile' modifier in C# has two effects: Inserts fences as necessary for the target processor Prevents certain compiler optimizations On x86 / amd64, (1) is irrelevant. Those processors don't require fences for volatile semantics. (ia64 is different, though.) So, we are down to (2). But, for examples th...
Are there any builtin IMultiValueConverts in WPF?
I'm writing a MultiBinding containing two bindings - each returning a bool. Using MultiBindings you need to specify an IMultiValueConverter. In my case this converter should take two bools and return the AND of them. This is really simple to write, but do I have to? This feels like the most basic MultiValueConverter, and I don't want to ...
