Likewise, if I'm returning an instance of this class from an implementation of, this would mean that all the getters are accessed, because that's something the serializer would do. , I would like to see the instantiation and setter access warnings gone, because using it like this would mean that OrmLite would instantiate and populate this class for me. The combination of 2 and 3 would be ideal for my purpose.īasically, if I have a class called MyDatabaseModel and using it in OrmLite like this: If a class is used as a generic parameter to a generic class or method.If a class extends another class or implements interface.If a class is in a certain namespace (this would be configurable on the project level as there are no namespace attributes in C#). ![]() ReSharper disable ClassNeverInstantiated.GlobalĬould we please have a way to configure these warnings for certain class patterns so they don't have to be disabled manually?Ī couple of solutions pop into my mind about how we could configure disabled warnings: ReSharper disable UnusedAutoPropertyAccessor.Global Instead, our ORM library (ServiceStack.OrmLite) takes care of construction and population of these class instances, doing it through reflection.Įvery time I create one of these classes, I'm getting a bunch of warnings which I have to disable manually using comments or attributes: However, they are never instantiated directly by our code, neither are setters accessed by our code. These classes are public and have public properties with getters and setters. Hello, is there any form of annotation available inside xaml files - //arkus. When we check the adjusted variable for inequality to 'null', ReSharper warns us again that this comparison is always false.In our codebase there are a bunch of classes which basically reflect the layout of our database tables. Annotations (UsedImplicitly) for xaml Follow. Then, it keeps tracking the adjusted variable that was initialized with this expression, and now is also 'null'. First of all, it highlights the function call with a null argument, warning that this expression is always null. When we call the Adjust function with a 'null' argument, ReSharper finds and highlights a bunch of issues at once. Anyway, the main thing here is the contract annotation attribute that describes how the function handles the input value. ![]() You can easily read the code of this example to see that the function works this way, but in real-life code this dependency might not be that obvious. The attribute argument in this case means, that a null argument always yields a null return. In this example, we decorated the function Adjust with the contract annotation attribute. To quickly understand how and why you could use contract annotations, look at the example below. ReSharper Annotations help reduce false positive warnings, explicitly declare purity and nullability in your code, deal with implicit usages of members, support special semantics of APIs in ASP. You can also annotate functions in existing binary modules using external annotations. There is a newer version of this package available. If you want to do it in your source code, reference the JetBrains.Annotations namespace. ![]() You can implement contract annotations by decorating your functions with the. The easiest way to benefit from ReSharpers code annotations is to add the annotation attributes to symbols of your source code and make ReSharper analyze your solution with greater accuracy and insight. For more information, refer to Value and nullability analysis. For example, if your function never returns 'null' independently on the input, you can use the attribute. ![]() Sometimes you may want to use simpler alternatives instead of contract annotations. The mechanism of contract annotations allows creating APIs that could be consumed in easier and safer way. Contract annotations let you define expected outputs for given inputs, or put in other words, define dependencies between reference type and boolean arguments of a function and its return value.
