Question

After pre-compiled a ASP.NET web site, I got many files with the names like

App_Web_accountbalance.aspx.dfa151d5.dll

Do you know the rule for the random chars (in bold) above?

Can we fix the random chars?

The reason to fix it is that if we modify AccountBalance.aspx file later and re-compile the web site, can we just replace App_Web_accountbalance.aspx.dfa151d5.dll.

Thank you.

1) you can generate single assembly per web application if you want. So when you make a change in web application, you only need to deploy just one dll.

for this, you can check option “Use fixed naming and single page assemblies”

2) Reference from MSDN Article: “The assembly names are generated automatically by the compiler and it is therefore not obvious which assemblies map to which source files. The compiler also creates new names each time it runs, so that the names of assemblies might not be the same after each compilation. In addition, if source files have changed, the compiler might batch up source files differently, meaning that the resulting assemblies do not necessarily represent the same source files. If you are maintaining a deployed Web site and want to update only the assemblies for recent changes, the output from batch compilation can make that job more complicated.

To help you in this situation, aspnet_compiler.exe supports an option specifically designed for packaging and release management: the -fixednames option. This option enables you to create compiler output that has two benefits. The first is that the assemblies produced by the compiler have the same names each time you compile. The second is that the assemblies are based on the same input files each time.”
