# <regasm>

Registers an assembly, or set of assemblies for use from COM clients.

Refer to the Regasm documentation for more information on the regasm tool.

### Parameters

Attribute | Type | Description | Required
--- | --- | --- | ---
assembly | file | The name of the file to register. This is provided as an alternate to using the task's `assemblies`. | False
codebase | bool | Set the code base registry setting. | False
regfile | file | Registry file to export to instead of entering the types directly into the registry. | False
registered | bool | Only refer to already registered type libraries. | False
typelib | file | Export the assemblies to the specified type library and register it. | False
unregister | bool | Unregister the assembly. The default is false. | False
failonerror | bool | Determines if task failure stops the build, or is just reported. The default is true. | False
if | bool | If true then the task will be executed; otherwise, skipped. The default is true. | False
timeout | int | The maximum amount of time the application is allowed to execute, expressed in milliseconds. Defaults to no time-out. | False
unless | bool | Opposite of `if`. If false then the task will be executed; otherwise, skipped. The default is false. | False
verbose | bool | Determines whether the task should report detailed build log messages. The default is false. | False

### Framework-configurable parameters

Attribute | Type | Description | Required
--- | --- | --- | ---
exename | string | The name of the executable that should be used to launch the external program. | False
managed | ManagedExecution | Specifies whether the external program should be treated as a managed application, possibly forcing it to be executed under the currently targeted version of the CLR. | False
useruntimeengine | bool | Deprecated. Specifies whether the external program is a managed application which should be executed using a runtime engine, if configured. The default is false. | False

### Nested Elements:

#### <assemblies>

The set of assemblies to register, or unregister.

#### </assemblies>

#### <references>

The set of assembly references.

#### </references>

#### <arg>

The command-line arguments for the external program.

Represents a command-line argument.

When passed to an external application, the argument will be quoted when appropriate. This does not apply to the `line` parameter, which is always passed as is.

### Parameters

Attribute | Type | Description | Required
--- | --- | --- | ---
dir | directory | The value for a directory-based command-line argument; will be replaced with the absolute path of the directory. | False
file | file | The name of a file as a single command-line argument; will be replaced with the absolute filename of the file. | False
if | bool | Indicates if the argument should be passed to the external program. If true then the argument will be passed; otherwise, skipped. The default is true. | False
line | string | List of command-line arguments; will be passed to the executable as is. | False
path | <path> | The value for a PATH-like command-line argument; you can use `:` or `;` as path separators and NAnt will convert it to the platform's local conventions, while resolving references to environment variables. | False
unless | bool | Indicates if the argument should not be passed to the external program. If false then the argument will be passed; otherwise, skipped. The default is false. | False
value | string | A single command-line argument; can contain space characters. | False

### Nested Elements:

#### <path>

Sets a single command-line argument and treats it like a PATH - ensures the right separator for the local platform is used.

#### </path>

### Examples

- A single command-line argument containing a space character.

      <arg value="-l -a" />

- Two separate command-line arguments.

      <arg line="-l -a" />

- A single command-line argument with the value `\dir;\dir2;\dir3` on DOS-based systems and `/dir:/dir2:/dir3` on Unix-like systems.

      <arg path="/dir;/dir2:\dir3" />

#### </arg>

### Examples

- Register types in a single assembly.

      <regasm assembly="myAssembly.dll" />

- Register types of an assembly and generate a type library containing definitions of accessible types defined within the assembly.

      <regasm assembly="myAssembly.dll" typelib="myAssembly.tlb" />

- Register types of set of assemblies at once, while specifying a set of reference assemblies.

      <regasm codebase="true">
          <assemblies>
              <include name="OutlookAddin.dll" />
              <include name="OfficeCoreAddin.dll" />
          </assemblies>
          <references>
              <include name="CommonTypes.dll" />
          </references>
      </regasm>
