VSSDK002 PackageRegistration matches Package

The PackageRegistrationAttribute.AllowsBackgroundLoading parameter on your VS package class should indicate whether your class derives from AsyncPackage.

Examples of patterns that are flagged by this analyzer

[PackageRegistration(UseManagedResourcesOnly = true)]
class MyCoolPackage : AsyncPackage
{
}

or

[PackageRegistration(UseManagedResourcesOnly = true, AllowsBackgroundLoading = true)]
class MyCoolPackage : Package
{
}

Solution

Update the PackageRegistration attribute to match the base type of your package class. Specifically, the AllowsBackgroundLoading parameter should be set to true if and only if your package derives from AsyncPackage.

[PackageRegistration(UseManagedResourcesOnly = true)]
class MyCoolPackage : Package
{
}

or

[PackageRegistration(UseManagedResourcesOnly = true, AllowsBackgroundLoading = true)]
class MyCoolPackage : AsyncPackage
{
}

A code fix is offered for this diagnostic to automatically apply this change.
