Hi, I am a newbie trying to learn Prism. I did not get the basic shell window displayed after implementing the hello world hands on lab that appeared in the prism guideline.

I developed it under vs2012, the compilation succeeded but no window was shown.

I have tried following the HelloWorld Hands On Lab in Visual Studio 2012 and I could shown the Shell window without problems.

It would be helpful if you could provide us with the solution you obtained after completing the lab so that we could look at it and help you find the cause behind this.

Also, it could be useful if you could tell us which version of Windows and .NET Framework you are using.

Hi Damian, Thanks so much for your prompt reply. I  am happy to report that I just discovered that I had 

the statement to execute the Run method within the App.xaml.cs file commented out, and I forgot to remove the comment

after I finished implementing the main shell.  I'm Sorry for the time that it took you to try the lab.. I hope not to get into more

classic newbie mistakes from now on. Thanks again.

I am glad you could find the cause behind the problem :)
