Question

How do i set the version on a asp.net project? as the properties dont contain any thing…

there is no project file in the folder where the webpage is.

Answer 1

Assuming you’re using a Web Application (rather than a Web Site project) then you should find that you have an AssemblyInfo.cs file in your “properties” folder.

This will contain attributes such as:

[assembly: AssemblyVersion("1.0.0.0")]
[assembly: AssemblyFileVersion("1.0.0.0")]

If you have a Web Site project then you can manually add a new .cs file and put these attributes in it.

You can find more info about these attributes here (on SO):

What are differences between AssemblyVersion, AssemblyFileVersion and AssemblyInformationalVersion?

update

Having just read the above post it might be that AssemblyInformationalVersion is the more appropriate attribute to use if you’re just trying to hold info that you’d only display to a user.

update II

This is some “quick and dirty” code that’ll grab the InformationalVersion from the attribuite:

string version = Assembly
                .GetExecutingAssembly()
                .GetCustomAttributes(
                   typeof(AssemblyInformationalVersionAttribute), true)
                .Where(x => x.GetType() == 
                   typeof(AssemblyInformationalVersionAttribute))
                .Cast<AssemblyInformationalVersionAttribute>()
                .First()
                .InformationalVersion;

If I were you I’d write a class that holds the attribute value, and the code above that access it, such that you can implement your version number using this attribute or whatever you like and then change the way you implement it over time.
