Classes were generated on a hyper-v server using the Visual Studio GUI, but you can do the same using
|
|
mgmtclassgen.exe. Below are some examples:
|
|
|
|
mgmtclassgen.exe Msvm_ComputerSystem /N root\virtualization /L CS /O CloudStack.Plugin.WmiWrappers /P ComputerSystem.cs
|
|
mgmtclassgen.exe Msvm_VirtualSystemManagementService /N root\virtualization /L CS /O CloudStack.Plugin.WmiWrappers /P VirtualSystemManagementService.cs
|
|
mgmtclassgen.exe Msvm_VirtualSystemGlobalSettingData /N root\virtualization /L CS /O CloudStack.Plugin.WmiWrappers /P VirtualSystemGlobalSettingData.cs

BUT, you have to tweak the generated code, because it does not deal with NULL method parameters properly.
|
|
E.g. when a method completes immediately, the returned out parameters include a "Job" property that has a NULL value.
|
|
The generated code will attempt to call ToString() on this NULL value.
|
|
|
|
ALSO, you have to tweak the generated code to expose useful details such as the WMI name for the class.
|
|
E.g. the generated code creates a wrapper called class ComputerSystem for WMI objects of class Msvm_ComputerSystem.
|
|
Thus, there is a mismatch in the class name and the corresponding WMI class, and the WMI class name is a private
|
|
constant static member. The tweak involves making this member public.
