The PrecompilationFlags class defines the behavior of the build manager during precompilation. The System.Web.Compilation.ClientBuildManager class takes PrecompilationFlags as one of its constructor parameters. Precompilation can be performed programmatically through System.Web.Compilation.ClientBuildManager or through the Aspnet_compiler.exe command-line tool.
An System.Security.AllowPartiallyTrustedCallersAttribute attribute is generated for the assemblies, which means the assemblies can be called by partially trusted code. The /aptca flag will be added as a compilation symbol.
The application will be built "clean": Any previously compiled components will be recompiled. This field corresponds to the -c switch on Aspnet_compiler.exe.
The /define:CodeAnalysis flag will be added as a compilation symbol.
The default value; no special behavior specified for precompilation.
The assembly is not fully signed when created. The assembly can be signed later by a signing tool such as Sn.exe. The /delaysign flag will be added as a compilation symbol.
The assembly is generated with fixed names for the Web pages. The files are not batched during compilation and instead are compiled individually to produce the fixed names.
The compiler will emit debug information. This field corresponds to the -d switch on Aspnet_compiler.exe.
The target directory can be overwritten. This field corresponds to the -f switch on Aspnet_compiler.exe for a previously precompiled target.
The deployed application will be updatable. This field corresponds to the -u switch on Aspnet_compiler.exe.
