I have the following property defined. MyLibrary.PumpSignal is an enum as follows:
Public Enum PumpSignal As Integer
PumpOff = 0
PumpOn = 1
End Enum
[Code].....
.NET keeps complaining that the Return value from PumpState is no cls-compliant.
I have a base class with a static function that returns a typed dataset. I have several classes that inherit the base class with a non-static function that returns the same typed dataset. On these methods I get the 'Return type of parameter yadda
is not CLS-compliant' I don't understand where this is coming from. I have non unsigned integers/etc. in this dataset.
I'm getting the following warning message... Return type of function 'ConnectionNew' is not CLS-compliant.
...for this function:
Public Function ConnectionNew(ByVal DataBaseName As String) As MySqlConnection
Dim connection As MySqlConnection = Nothing
[code].....
I wrote a generic EventArgs class in my VB.NET solution:
Public Class EventArgs(Of T)
Inherits EventArgs
Private _eventData As T
[code].....
When I use it as in the following example, it says that e is not CLS-compliant.
Event MarketModeChanged(ByVal sender As Object, ByVal e As EventArgs(Of Integer))
I'm using LINQ to SQL as my data access layer for a new project.I have added my database tables to the designer and all is well.Whenever I use one of these classes in a function, Visual Studio warns me that 'Type xxxx is not CLS-compliant' or that 'Return type of function xxxx is not CLS-compliant' Is this a problem with the classes that LINQ to SQL generates? Does it matters? Can I disable these warnings anywhere? My VS error list is clogged up with these warnings making it hard to see anything else.
View 4 RepliesAs an OSS library author, I've always tried to make my stuff CLS compliant. But MS doesn't make this easy. They often put you in catch-22 situations, such as the following:You cannot have a protected variable differing only in case from the public property.You cannot have protected or public variables starting in an underscore or 'm_'. If you want to make a class really extensible, you often need to have protected variables matching public properties. Your least ugly exit is to add a suffix to the variable, like "Var" or "Value". That's nasty and unacceptable to me. I like clean code.I know of no .NET languages that don't support variables starting in an underscore, and I've used them in many places where the variable needs to be visible to subclasses.
I'm tired of the warnings, and I'm planning on turning off CLS compliance at the assembly level on my 30+ C# libraries.Are there any actual problems with turning off CLS compliance on libraries? Any real problems with doing this? Microsoft has issued unheedable guidance on software for decades, with less that 5% of it being worth the bytes it was encoded in. I can't find any evidence that this best practice has any real effect on anything. But, to be careful, I'm checking. And no, this is not a duplicate of the inverse of this question: Any reason not to mark a DLL as CLSCompliant?I'm looking for actual results and effects here, not the advice of a MS intern. For example, if IronPython, IronRuby, or F# are unable to read or write a variable starting with an underscore, that's an effect, although it would only cause a problem for users subclassing certain objects. If a language or tool is completely unable to use an assembly unless it is marked CLS compliant, now that's a big deal.
This question is more out of curiosity than a project requirement or a problem.I have a Non-CLS compliant code in one language (say C#), and I need to use it like that only in my current language (across projects, so making internal is not a choice), and at the same time want to allow other languages (say VB) to be able to call the conflicting implementations without generating compile time error.
For instance,
//C#
public class SecurityService

I'm working up a system where I plan on using RealProxy objects to enable intercepting method calls against a set of objects, handling the call, and then returning appropriate results. This works just find for simple return types like strings or ints, but I can't seem to return objects from the RealProxy.Invoke method. Everything works. I get no errors, but the returned value is always NOTHING, instead of an object.
I've worked up the smallest sample code I could, and have included it below. Essentially, just call RPtest and single step through. The code creates a simple object, RPTestA, with a string field and an object valued field It then retrieves the string

In order to return a value from a VB.NET function one can assign a value to the "Functions Name" or use "return value." I sometimes see these inter-mixed in the same function. Personally, I prefer the return. My question is, what is the internal difference, if any, between the two?
