.NET Services Installation Tool (Regsvcs.exe)

The .NET Services Installation tool performs the following actions:

  • Loads and registers an assembly.
  • Generates, registers, and installs a type library into a specified COM+ 1.0 application.
  • Configures services that you have added programmatically to your class.
regsvcs [/c | /fc | /u] [/tlb:typeLibraryFile] [/extlb]
[/reconfig] [/componly] [/appname:applicationName]
[/nologo] [/quiet]assemblyFile.dll 
Argument Description
assemblyFile.dll The source assembly file. The assembly must be signed with a strong name. For more information, see Signing an Assembly with a Strong Name.
Option Description
/appname:applicationName Specifies the name of the COM+ 1.0 application to either find or create.
/c Creates the target application.
/componly Configures components only; ignores methods and interfaces.
/exapp Specifies to the tool to expect an existing application.
/extlb Uses an existing type library.
/fc Finds or creates the target application.
/help Displays command syntax and options for the tool.
/noreconfig Does not reconfigure an existing target application.
/nologo Suppresses the Microsoft startup banner display.
/parname:name Specifies the name or id of the COM+ 1.0 application to either find or create.
/reconfig Reconfigures an existing target application. This is the default.
/tlb:typelibraryfile Specifies the type library file to install.
/u Uninstalls the target application.
/quiet Specifies quiet mode; suppresses the logo and success message display.
/? Displays command syntax and options for the tool.

Remarks

Regsvcs.exe requires a source assembly file specified by assemblyFile.dll. This assembly must be signed with a strong name. For more information on strong name signing, see Signing an Assembly with a Strong Name. The names of the target application and the type library file are optional. The applicationName argument can be generated from the source assembly file and will be created by Regsvcs.exe, if it does not already exist. The typelibraryfile argument can specify a type library name. If you do not specify a type library name, Regsvcs.exe uses the assembly name as the default.

When Regsvcs.exe registers a component's methods, it is subject to the demands and link demands on those methods. Because the tool executes in a fully-trusted environment, most demands for a permission succeed. However, Regsvcs.exe cannot register components with methods protected by a demand or link demand for the StrongNameIdentityPermission or the PublisherIdentityPermission.

If Regsvcs.exe fails while performing any of these actions, it displays corresponding error messages. For a more detailed description of the possible failures and error messages, see Manually Registering an Assembly.

Examples

The following command adds all public classes contained in myTest.dll to myTargetApp (an existing COM+ 1.0 application) and produces the myTest.tlb type library.

regsvcs /appname:myTargetApp myTest.dll

The following command adds all public classes contained in myTest.dll to myTargetApp (an existing COM+ 1.0 application) and produces the newTest.tlb type library.

regsvcs /appname:myTargetApp /tlb:newTest.tlb myTest.dll
