Regarding Opening Projects / Solutions in Visual Studio by Default
Within Windows, you should be able to set the default application to open your Project files with through the following steps :
- Right-click on a Project or Solution File on your local machine (outside of Visual Web Developer or Visual Studio).
- Choose Open with...
- Select Choose default program...
- Select Visual Studio 2008.
- Ensure the "Always use the selected program to open this kind of file" checkbox
is checked.
- Click "OK".
Your Project and Solution files should now open by default within Visual Studio instead of Visual Web Developer.
Regarding DLL Files
It should be noted that DLL (Dynamic Link Libraries) files are always going to be generated when you actually build or publish your applications and projects.
These files are necessary compiled forms of your applications and your code that are used within your applications (and can be used as references within other applications).
Visual Studio is going to generate these as well.
