VB.Net Error setting auto increment in assembly version

Hi All,

I get this error when setting the assembly version to autoincrement in vs2005.

the AssembyInfo.vb file has the following:

<Assembly: AssemblyVersion("1.0.0.*")>
<Assembly: AssemblyFileVersion("1.0.0.*")>

The error (warning) is:

Warning      3      Possible problem detected while building assembly 'ATMS': The version '1.0.0.*' specified for the 'file version' is not in the normal 'major.minor.build.revision' format

is your assembly strong named?

Hi newyuppie,

Am new to .Net and this will be my first major app in vb.net, so excuse the ignorance, but please could you give me a bit of a run-down on strongly naming an assembly. I've heard of it, but don't know how it works.

Hi Again All,

I have read up on strong assemblies, naming and signing and have signed my assembly.

I still get the error.

By the way, if I go into Sign the Assembly and create a new key from the option to create a key or browse for a key, a dialog box appears which allows you to name the key and set the password.

In that dialog box, the fields are enabled, but I cannot type anything in there, but the paste function works. ???? Any ideas?

Thanks again
What does it mean to be "Always On"?

if you are using vb2005 its actually very easy. you need to go to project properties (rightclick on the prohect name on the SOlution Explorer to the right and select properties).

on this new window, on your left you get different panes. go to the Signing pane and check "Sign the assembly". Then on the dropdown list select <New...> and create a new key with a password you provide. then save and compile. see if this resolves the assembly version issue.

Yep, done that again and this time specified one with a password, but still get the same warning.

I am wondering if it is something to do with the format of the version string.

Here is the bit of the assemblyinfo.vb file

' You can specify all the values or you can default the Build and Revision Numbers
' by using the '*' as shown below:
' <Assembly: AssemblyVersion("1.0.*")>

<Assembly: AssemblyVersion("1.0.0.*")>
<Assembly: AssemblyFileVersion("1.0.0.*")>

<Assembly: NeutralResourcesLanguageAttribute("en-NZ")>

yeah apparently AssemblyFileVersion does not do well with *
nevertheless, you can use the * thing in AssemblyVersion without problems. and from what i understand, AssemblyFileVersion defaults to AssemblyVersion, so maybe you can remove the <Assembly: AssemblyFileVersion("1.0.0.*")> alltogether and only keep the <Assembly: AssemblyVersion("1.0.0.*")>.

does that help?

from MSDN documentation "Understanding and Using Assemblies and Namespaces in .NET"
Table 1. Standard assembly attributes

Attribute Meaning
AssemblyCompany Company shipping the assembly
AssemblyCopyright Copyright information
AssemblyCulture Enumeration indicating the target culture for the assembly
AssemblyDelaySign True to indicate that delayed signing is being used
AssemblyDescription Short description of the assembly
AssemblyFileVersion String specifying the Win32 file version. Defaults to the AssemblyVersion value.
AssemblyInformationalVersion Human-readable version; not used by the common language runtime
AssemblyKeyFile Name of the file containing keys for signing the assembly
AssemblyKeyName Key container containing a key pair to use for signing
AssemblyProduct Product Name
AssemblyTitle Friendly name for the assembly
AssemblyTrademark Trademark information
AssemblyVersion Version number expressed as a string.

You can also define your own custom attributes by inheriting from the System.Attribute class. These attributes will be available in the assembly manifest just like the attributes listed above.

Warning is GONE!! Done by commenting out the <Assembly: AssemblyFileVersion("1.0.0.*")>

Thanks a million. I've learnt a lot from a silly little thing like that!
