Non compliant tools must be which of the following

In addition, for generic types:. NET common type system includes many built-in types that are supported directly by the common language runtime and are specially encoded in an assembly's metadata. Of these intrinsic types, the types listed in the following table are CLS-compliant. Boxed value types. Typed references, which are special constructs that contain a reference to an object and a reference to a type.

Typed references are represented in. NET by the TypedReference class. The following example illustrates the problem of CLS compliance in a method signature and in generic type instantiation. You get four compiler warnings when you try to compile this example. To eliminate the compiler warnings, replace the non-CLS-compliant types in the InvoiceItem public interface with compliant types:.

In addition to the specific types listed, some categories of types are not CLS compliant. These include unmanaged pointer types and function pointer types. The following example generates a compiler warning because it uses a pointer to an integer to create an array of integers. Because some programming languages are case-insensitive, identifiers such as the names of namespaces, types, and members must differ by more than case. Two identifiers are considered equivalent if their lowercase mappings are the same.

The following C example defines two public classes, Person and person. Because they differ only by case, the C compiler flags them as not CLS-compliant. Programming language identifiers, such as the names of namespaces, types, and members, must conform to the Unicode Standard.

This means that:. The first character of an identifier can be any Unicode uppercase letter, lowercase letter, title case letter, modifier letter, other letter, or letter number. For information on Unicode character categories, see the System. UnicodeCategory enumeration.

Subsequent characters can be from any of the categories as the first character, and can also include non-spacing marks, spacing combining marks, decimal numbers, connector punctuation, and formatting codes.

Before you compare identifiers, you should filter out formatting codes and convert the identifiers to Unicode Normalization Form C, because a single character can be represented by multiple UTFencoded code units.

Member names within a particular scope such as the namespaces within an assembly, the types within a namespace, or the members within a type must be unique except for names that are resolved through overloading. This requirement is more stringent than that of the common type system, which allows multiple members within a scope to have identical names as long as they are different kinds of members for example, one is a method and one is a field.

In particular, for type members:. Methods, properties, and events that have the same name must differ by more than just return type.

The following example illustrates the requirement that member names must be unique within their scope. It defines a class named Converter that includes four members named Conversion. Three are methods, and one is a property. The method that includes an Int64 parameter is uniquely named, but the two methods with an Int32 parameter are not, because return value is not considered a part of a member's signature.

The Conversion property also violates this requirement, because properties cannot have the same name as overloaded methods. Individual languages include unique keywords, so languages that target the common language runtime must also provide some mechanism for referencing identifiers such as type names that coincide with keywords. For example, case is a keyword in both C and Visual Basic.

However, the following Visual Basic example is able to disambiguate a class named case from the case keyword by using opening and closing braces. Otherwise, the example would produce the error message, "Keyword is not valid as an identifier," and fail to compile. The following C example is able to instantiate the case class by using the symbol to disambiguate the identifier from the language keyword.

Without it, the C compiler would display two error messages, "Type expected" and "Invalid expression term 'case'. However, not all languages support operator overloading or the definition of custom operators. If you choose to implement these conversion operators, you should also provide an alternate way to perform the conversion. We recommend that you provide From Xxx and To Xxx methods.

The following example defines CLS-compliant implicit and explicit conversions. It creates a UDouble class that represents an unsigned, double-precision, floating-point number. It also defines a ToDouble method as an alternative to the implicit conversion operator and the ToSingle , FromDouble , and FromSingle methods as alternatives to the explicit conversion operators.

All dimensions of an array must have a lower bound of zero. The following example creates a non-CLS-compliant array with a lower bound of one. Despite the presence of the CLSCompliantAttribute attribute, the compiler does not detect that the array returned by the Numbers. All array elements must consist of CLS-compliant types. The following example defines two methods that return non-CLS-compliant arrays. The first returns an array of UInt32 values.

The second returns an Object array that includes Int32 and UInt32 values. Although the compiler identifies the first array as non-compliant because of its UInt32 type, it fails to recognize that the second array includes non-CLS-compliant elements. Overload resolution for methods that have array parameters is based on the fact that they are arrays and on their element type.

CLS-compliant interfaces can define properties, events, and virtual methods methods with no implementation. A CLS-compliant interface cannot have any of the following:. Static methods or static fields. Both the C and Visual Basic compilers generate compiler errors if you define a static member in an interface.

Both the C and Visual Basic compilers generate compiler errors if you define a field in an interface. Methods that are not CLS-compliant. For example, the following interface definition includes a method, INumber. GetUnsigned , that is marked as non-CLS-compliant.

This example generates a compiler warning. If a CLS-compliant framework does expose a class that implements a non-CLS compliant interface, it should also provide concrete implementations of all non-CLS-compliant members. CLS-compliant language compilers must also allow a class to provide separate implementations of members that have the same name and signature in multiple interfaces.

Both C and Visual Basic support explicit interface implementations to provide different implementations of identically named methods. Visual Basic also supports the Implements keyword, which enables you to explicitly designate which interface and member a particular member implements.

The following example illustrates this scenario by defining a Temperature class that implements the ICelsius and IFahrenheit interfaces as explicit interface implementations. For example, the following code tries to define an enumeration whose underlying type is UInt32 and generates a compiler warning. RTSpecialName attribute.

This enables you to reference the field value implicitly. An enumeration includes literal static fields whose types match the type of the enumeration itself. For example, if you define a State enumeration with values of State. On and State. Off , State. Off are both literal static fields whose type is State. An enumeration that represents a set of mutually exclusive, named integer values.

This type of enumeration is indicated by the absence of the System. FlagsAttribute custom attribute. An enumeration that represents a set of bit flags that can combine to generate an unnamed value. This type of enumeration is indicated by the presence of the System.

For more information, see the documentation for the Enum structure. The value of an enumeration is not limited to the range of its specified values.

In other words, the range of values in an enumeration is the range of its underlying value. You can use the Enum. IsDefined method to determine whether a specified value is a member of an enumeration. The Common Language Specification requires all fields and methods to be accessed as members of a particular class.

Therefore, global static fields and methods that is, static fields or methods that are defined apart from a type are not CLS-compliant. If you try to include a global field or method in your source code, both the C and Visual Basic compilers generate a compiler error. The Common Language Specification supports only the standard managed calling convention. It doesn't support unmanaged calling conventions and methods with variable argument lists marked with the varargs keyword.

For variable argument lists that are compatible with the standard managed calling convention, use the ParamArrayAttribute attribute or the individual language's implementation, such as the params keyword in C and the ParamArray keyword in Visual Basic. Overriding an inherited member cannot change the accessibility of that member.

For example, a public method in a base class cannot be overridden by a private method in a derived class. There is one exception: a protected internal in C or Protected Friend in Visual Basic member in one assembly that is overridden by a type in a different assembly. In that case, the accessibility of the override is Protected. The following example illustrates the error that is generated when the CLSCompliantAttribute attribute is set to true , and Human , which is a class derived from Animal , tries to change the accessibility of the Species property from public to private.

The example compiles successfully if its accessibility is changed to public. Types in the signature of a member must be accessible whenever that member is accessible.

For example, this means that a public member cannot include a parameter whose type is private, protected, or internal. The following example illustrates the compiler error that results when a StringWrapper class constructor exposes an internal StringOperationType enumeration value that determines how a string value should be wrapped.

Nested types always have at least as many generic parameters as their enclosing type. These correspond by position to the generic parameters in the enclosing type. The generic type can also include new generic parameters. The relationship between the generic type parameters of a containing type and its nested types may be hidden by the syntax of individual languages. The calls to the ToString method, which each class inherits from Object. ToString , show that each nested class includes the type parameters of its containing class.

This encoding of generic type names is primarily of interest to developers who use reflection to access CLS-complaint generic types in a library.

If constraints are applied to a generic type, any types used as constraints must also be CLS-compliant. Offboarding Possible cause: Onboarding or offboarding failed on a wrong blob: wrong signature or missing PreviousOrgIds fields.

Troubleshooting steps: Check the event IDs in the View agent onboarding errors in the device event log section. Onboarding has failed. Troubleshooting steps: Check the troubleshooting steps in Troubleshoot onboarding issues on the device. Currently supported platforms: Enterprise, Education, and Professional.

Server is not supported. Known issues with non-compliance The following table provides information on issues with non-compliance and how you can address the issues. Possible cause: Sense service's startup type is set as "Delayed Start". Sometimes this causes the Microsoft Intune server to report the device as non-compliant by SenseIsRunning when DM session occurs on system start. Troubleshooting steps: The issue should automatically be fixed within 24 hours.

If the deployment tools used does not indicate an error in the onboarding process, but devices are still not appearing in the devices list in an hour, go through the following verification topics to check if an error occurred with the Microsoft Defender for Endpoint agent. Events which can indicate issues will appear in the Operational pane. You can attempt to troubleshoot them based on the solutions in the following table:.

There are additional components on the device that the Microsoft Defender for Endpoint agent depends on to function properly. If there are no onboarding related errors in the Microsoft Defender for Endpoint agent event log, proceed with the following steps to ensure that the additional components are configured correctly.

If the devices aren't reporting correctly, you might need to check that the Windows diagnostic data service is set to automatically start and is running on the device. The service might have been disabled by other programs or user configuration changes. First, you should check that the service is set to start automatically when Windows starts, then you should check that the service is currently running and start it if it isn't.

Use the command line to set the Windows diagnostic data service to automatically start:. A success message is displayed. Verify the change by entering the following command, and press Enter :.

Start the service. In the command prompt, type the following command and press Enter :. WinHTTP is independent of the Internet browsing proxy settings and other user context applications and must be able to detect the proxy servers that are available in your particular environment.

To ensure that sensor has service connectivity, follow the steps described in the Verify client connectivity to Microsoft Defender for Endpoint service URLs topic. If the verification fails and your environment is using a proxy to connect to the Internet, then follow the steps described in Configure proxy and Internet connectivity settings topic.

The following only applies to devices that have not yet received the August version 4. The update ensures that Microsoft Defender Antivirus cannot be turned off on client devices via system policy. Problem : The Microsoft Defender for Endpoint service does not start after onboarding. Symptom : Onboarding successfully completes, but you see error or error when trying to start the service.

You must ensure that it's not turned off by a system policy. Depending on the tool that you use to implement policies, you'll need to verify that the following Windows Defender policies are cleared:. The disableAntiSpyware setting is discontinued and will be ignored on all Windows 10 devices, as of the August version 4.

All Windows Defender services wdboot, wdfilter, wdnisdrv, wdnissvc, and windefend should be in their default state. Changing the startup of these services is unsupported and may force you to reimage your system. If you encounter issues while onboarding a server, go through the following verification steps to address possible issues.

For example:. In Services , check if the Microsoft Monitoring Agent is running on the server. For example,. The ISO standard was developed to help organizations of any size in any industry protect their data by effectively using an information security management system ISMS.
