The Media Center Sandbox

I found an example, ObjectModelApplicationContextInstallApplication.mcml, in Microsoft SDK folder and it works fine.

Now I have a different problem :) After the installation when I re-open the Media Center and click my application, the previous application still there!

I changed my codes in application.cs, for example I set all the ArrayListDataSet return values as null, changed the images links from the styles.mcml, changed some colors etc. But nothing has changed, why?

I applied the same codes in ObjectModelApplicationContextInstallApplication.mcml. In my opinion update process works fine but due to the entrypoints issue I can't see the latest exe in Media Center.

Do I have to change the GUID ID or assembly version?

Do I have to change the Setup.wxs file? I found this link:

http://msdn.microsoft.com/en-us/library/Aa369786

There are lots of information regarding updating the current application. Also it says the current application can be uninstalled by using the REMOVE="ALL" AND NOT UPGRADINGPRODUCTCODE but how?

I accomplished to set the installation process from MCML. As you know this time I can't see the new version of my application in MediaCenter. After the installation process, MediaCenter directly jumps to my application bur it shows the previous one :(

Additional info:

-?define Property_ProductVersion = "1.0.0.0" ?-

I have changed the line above in setup.wxs as:

-?define Property_ProductVersion = "1.0.0.1" ?-

Then the installation process has been completed via my Media Center application. I can see the new version info in Program Add Remove window. But nothing has changed in application.

Do I have to change these lines in stup.wxs ?

-Feature Id="APPROOTFEATURE"
Title="MyMediaCenter"
Level="1"-
-ComponentRef Id="MyMediaCenter.dll" />
-ComponentRef Id="Registration.xml" /-
-ComponentRef Id="Application.png" /-
-/Feature-

OR any comments? I need serious help.. How do you update your current application? I followed and applied the Microsoft SDK rules and I am not getting an error.. Can you share your sample projects or send me them as .rar or .zip?

Have you changed the version number of your assembly? If you don't the in-place installer (part of MSI) will not replace the assembly even if it is different.

Cheers,
Andrew

I have changed the assembly version from 1.0.0.0 to 1.0.0.1 then I compiled my project. This time everthing worked fine during the installation process and probably my assembly has been replaced.

Now I am getting a different error when I click my application in Media Center; also I am happy cus I am in progress :)

If I fix this new error probably I will learn the product upgrade issue in Media Center. Thank you for everything Andrew :)

Here is the event log:

The new assembly has been replaced but the previous assembly is still in GAC. Any comments?

I solved the problem!! I changed the new assembly version in the registration.xml as well. Now I am not getting error :)

Thank you for your support Andrew..
