powershell - $error variable not available in modules? -

I have a lot of interest in using the try..catch statement in power scripts (especially when Calling external programs / COM objects etc.), and then use the automatic $ error variable to deal with the error.

My problem is that I have found that when module, $ error variable no longer works. I think that there is something with it that you are actually running while calling a function within a module, but it is being provoked in some way. Why do anyone know here, or even better: the solution?

I have a workaround: to make any external calls using invoke-expression by using the -errorVariable parameter, but rather complex Is - and not always the right proof.

  What would the $ _ variable within the call block do?

visual studio 2010 - How to reinstall MVC 2 tools for VS2010? -



    I uninstalled ASP.Net MVC 2 device for Visual Studio 2010. How can I restore it? MVC2 downloads seem to include only the VS2008 device.   Whatever I said, says that MVC 2 has been included in VS2010, but the installation of an improvement did not fix it, and MVC 2 is not listed. Add VS2010 / Select a component in the Remove screen.      You will get your VS2010ToolsMVC2.msi VS2010 DVD under WCU \ ASPNETMVC - hopefully it will do!
