Solution Events in VS11 AddIns
For those of you having problems with your addin in Visual Studio 11 where the EnvDte.SolutionEvents is not fired: I have the solution!
It’s all about interfaces
Forget about the (old school?) SolutionEvents. By digging around in the Microsoft.VisualStudio.Shell.Interop namespace I stumpled upon the IVsSolutionEvents interface! Check out the following methods:
And subscription of course
But how do I tell VS I am interested in being called, hence I am implementing the interface? Within the OnConnection method from the IDTExtensibility2 interface you can subscribe yourself with the following piece of code:
public void OnConnection(object Application, ext_ConnectMode ConnectMode, object AddInInst, ref Array custom)
{
using (ServiceProvider sp = new ServiceProvider(
(Microsoft.VisualStudio.OLE.Interop.IServiceProvider)_applicationObject))
{
var solution = sp.GetService(typeof(SVsSolution)) as IVsSolution;
if (solution != null)
{
if (solution.AdviseSolutionEvents(this, out _solutionEventsCookie) != VSConstants.S_OK)
{
MessageBox.Show("Something went wrong.");
}
}
}
}
public void OnDisconnection(ext_DisconnectMode RemoveMode, ref Array custom)
{
using (ServiceProvider sp = new ServiceProvider(
(Microsoft.VisualStudio.OLE.Interop.IServiceProvider)_applicationObject))
{
var solution = sp.GetService(typeof(SVsSolution)) as IVsSolution;
if (solution != null)
{
if (solution.UnadviseSolutionEvents(_solutionEventsCookie) != VSConstants.S_OK)
{
MessageBox.Show("Something went wrong.");
}
}
}
}
Within each method you can easily return VSConstants.S_OK when everything is fine.
