WCF DataContract with readonly properties
Hi, I'm trying to return a complex type from a service method in WCF. I'm using C# and .NET 4. This complex type is meant to be invariant (the same way .net strings are). Furthermore, the service only returns it and never recieves it as an argument. If I try to define only getters on properties I get a run time error. I guess this is b...
What is the proper way to handle non-tracking self tracking entities?
Self tracking entities. Awesome. Except when you do something like return Db.Users; none of the self-tracking entities are tracking (until, possibly, they are deserialized). Fine. So we have to recognize that there is a possibility that an entity returning to us does not have tracking enabled. Now what??? Things I have tried F...

How to tell whether Code Access Security is allowed in library code
In .NET 4 Code Access Security (CAS) is deprecated. Whenever you call a method that implicitly uses it, it fails with a NotSupportedException, that can be resolved with a configuration switch that makes it fall back to the old behavior. We have a common library that's used in both .NET 3.5 and .NET 4, so we need to be able to tell wheth...

With 2010 just around the corner, I wanted to read about the improvements made to see if it was worth using 2010 to develop this application. So far I have read 2 maj...
Code Contracts: Do we have to specify Contract.Requires(...) statements redundantly in delegating methods?
I'm intending to use the new .NET 4 Code Contracts feature for future development. This made me wonder if we have to specify equivalent Contract.Requires(...) statements redundantly in a chain of methods. I think a code example is worth a thousand words: public bool CrushGodzilla(string weapon, int velocity) { Contract....
Library development - looking for valid use cases for suggested feature
I'm contributing to a library called Fasterflect whose purpose is "improving the developer experience of using reflection". As such, it provides an abstraction built on top of classic reflection and would be used in exactly the same scenarios. The following shows the current syntax for accessing members via an object instance: obj.SetP...
What is the best way get and hold property reference by name in c#
I want to know if there is a better way (than what I'm currently doing) to obtain and hold a reference to a property in another object using only the object and property string names.
