Applying aspects to 3rd party assemblies using PostSharp(programmersunlimited.wordpress.com)

submitted by bradygaster(4897) 9 months, 29 days ago

There is undocumented functionality in PostSharp 2.1 (2.1.2.3 or higher) that allows us to apply aspects to assemblies that we don’t have the source code for. It is also very, very nifty and demonstrates the power of PostSharp, even when the code isn't available. read more...

New in PostSharp 2.1: Navigating Code Relationships(www.sharpcrafters.com)

submitted by kingbee71(511) 10 months, 1 day ago

Gael Fraiteur covers the second feature of ReflectionSearch: querying the relationships between elements of code. Three kinds of relationships are supported: * type inheritance (classes and interfaces), * usage in statements (a type, method, or field is used inside a method body), * member type. read more...

New in PostSharp 2.1: Reflecting Custom Attribute(www.sharpcrafters.com)

submitted by kingbee71(511) 10 months, 5 days ago

One of the breaking innovations of PostSharp 1.0 in 2005 was the ability to execute aspect code at build time. Whereas other AOP frameworks developed complex declarative syntaxes to express “pointcuts”, PostSharp just allowed you to use System.Reflection to select the target of aspects. LINQ made it even easier to express complex code queries. Yet, some queries were difficult to achieve just with System.Reflection. For instance, it is fairly difficult and inefficient to get all properties annotated with the [DataMember] custom attribute: you have to enumerate all types (and do a recursion on nested types), get all properties of these types, and check the presence of this custom attribute on all properties. Wow. If we were querying a relational database, we would probably create an index on the Type column of the CustomAttribute table. Well, the analogy is not so stupid. Metadata in a .NET assembly is in fact a relational database, and there is a CustomAttribute table. What is more, PostSharp already builds these indexes internally. So why not making them available to user code? This was the principal idea behind this new feature: reflection search. read more...

PostSharp Principles: Day 12 - Aspect Providers, Part 1(www.sharpcrafters.com)

submitted by kingbee71(511) 10 months, 14 days ago

When it comes to building aspects, using the provided base classes such as OnMethodBoundaryAspect and LocationInterceptionAspect are quick and easy ways to implement a simple aspect. But they have their limitations: each aspect can only implement one transformation. But what if you need to encapsulate a design pattern made of several transformations? We’re going to look at two ways of building complex aspects: aspect providers today and advices tomorrow. read more...

PostSharp Principles: Day 9 - Aspect Lifetime Scope, Part 1(www.sharpcrafters.com)

submitted by kingbee71(511) 10 months, 19 days ago

Aspects have a lifetime as well as a scope just like classes in your project. Understanding this cycle is important for producing quality aspects as well as getting aspects to do what you need them to do. Today we’re going to cover the lifecycle. read more...

PostSharp Principles: Day 4 - OnMethodBoundaryAspect(www.sharpcrafters.com)

submitted by kingbee71(511) 10 months, 26 days ago

Dustin Davis revisits the OnMethodBoundaryAspect class by building a profiler aspect to identify slow executing methods. As noted in Day 2, OnMethodBoundaryAspect has 4 methods for us to access specific points in a methods execution OnEntry - Before the execution of the method body OnExit - Always called when a method is done executing even if there was an error OnSuccess - Called only when a method is done executing and there were no exceptions OnException - Called only when a method has stopped executing due to an unhandled exception read more...

submitted by kingbee71(511) 11 months, 25 days ago

PostSharp 2.1 offers NuGet packaging. NuGet is a very convenient way to install PostSharp. It provides a streamlined experience and does not require administrative privileges. But most importantly, it will allow third-party vendors and OSS projects to handle dependencies to PostSharp in a very easy way. If your project or product ships aspects, make it easy for developers: include PostSharp as a NuGet dependency. read more...
