Hi all,

 I have a Silverlight project that I created with the 90-day trial version of Visual Studio 2008 ( unfortunately I don't remember if it was the Professional Trial or the Standard version trial ). I then purchased a copy of Visual Studio 2008 Standard and the Silverlight project won't open.

 
Is Silverlight compatible with the Standard Version of Visual Studio 2008?

Any help would be great! Thanks! 

Silverlight Tools should work with VS Standard.  Did you re-install the tools package?

 Hmmm, ok. Yeah, I tried re-installing the Visual Studio Silverlight Tools and I get an error telling me:

 An Error Has Occurred:
Silverlight Tools cannot be installed because one or more of the following conditions is true:

1. Visual Studio 2008 RTM is not installed.
2. The Web Authoring feature of Visual Studio is not installed.
3. A previous version of the Silverlight Runtime is installed.
4. A previous version of the Silverlight SDK is installed.
5. The Visual Studio Update KB949325 is installed.
6. A previous version of Silverlight Tools is installed.

I have uninstalled the Silverlight Tools prior to attempting to re-install ( complete with a reboot ), so I'm pretty sure it's not #6. Do I need to do something besides the standard Visual Studio install to get #1 and #2? And I also have Silverlight 2 Beta 1 installed, so I think I'm good on #3 and #4.

Any ideas?

Thanks!
 

As long as you can create a website in VS, you have the web components.  Assuming you did a default install, full install, or didn't specifically remove it from a custom install, you should be fine.  The runtime and SDK should be version 2.0.30226.2 if I recall correctly (I don't have a machine handy to verify), can you double check those?  Also, if you go to Add/Remove Programs, make sure you don't have the Silverlight Tools for VS already installed or KB 949325 (if you have Vista, the latter will appear on the Installed Updates page; if you have a pre-Vista system, you need to select the checkbox to show updates).  Let me know what you find out.  You might also try uninstalling the SL runtime and SDK, though those really shouldn't be blocking the installer.

 Ok, after uninstalling the SL runtime and SDK I was able to install the Visual Studio Silverlight Tools Add-On and then re-install both the SL runtime and the SDK. However, I still get an error when attempting to either create a Silverlight project or open an existing one:

The project file ‘C:\Silverlight\SL.csproj’ cannot be opened.

This project type is not supported by this installation.

Any ideas? I'm going to try uninstalling the SDK and re-installing it again just to make sure it takes.

Yes. but debugging SL project in Standard edition doesn't work like Professional edition or team system., There is no checkedbox for Silverlight debugging in properties.
