AssemblyName | Gets or sets the name of the target assembly. (Inherited from ProvideDependentAssemblyAttribute.) |
|
CodeBase | Gets or sets a relative path from $PackageFolder$, or an absolute path rooted from an environment variable substitution (of format %variable%). (Inherited from ProvideDependentAssemblyAttribute.) |
|
Culture | Gets or sets a string that specifies the language and country/region of the assembly. (Inherited from ProvideDependentAssemblyAttribute.) |
|
Guid | Gets the identifier of this attribute instance. (Inherited from ProvideDependentAssemblyAttribute.) |
|
PublicKeyToken | Gets or sets a 16-character hexadecimal number which is the token part of the strong name of the assembly being redirected. (Inherited from ProvideDependentAssemblyAttribute.) |
|
TypeId | Gets the current instance of this attribute. (Inherited from RegistrationAttribute.) |
|
Version | Gets or sets the version of the assembly to use instead of the originally-requested version. |

Remarks
By using the ProvideCodeBase attribute, you can specify a code base for an assembly in an extension without manually updating the exe.config file. This attribute indicates the location of the assembly so that the CLR can find it.
Adding a ProvideCodeBase assembly attribute is an easy way to add a code base entry to the pkgdef file. The pkgdef file is used to install the extension.
The following example shows a ProvideCodeBase entry in the AssemblyInfo.cs or AssemblyInfo.vb file:
<Assembly: ProvideCodeBase(AssemblyName:="ClassLibrary1",
Version:="1.0.0.0", CodeBase:="$PackageFolder$\ClassLibrary1.dll")>
[assembly: ProvideCodeBase(AssemblyName = "ClassLibrary1",
Version = "1.0.0.0", CodeBase = "$PackageFolder$\\ClassLibrary1.dll")]
When you build the project, the following entry is added to the pkgdef file:
[$RootKey$\RuntimeConfiguration\dependentAssembly\codeBase\{D5206E57-D855-61F6-3D7E-EF7F72D9FAA7}]
"name"="ClassLibrary1"
"publicKeyToken"=""
"culture"="neutral"
"version"="2.0.0.0"
"codeBase"="$PackageFolder$\ClassLibrary1.dll"
You can also add a codeBase entry directly to a pkgdef file.
Thread Safety
Any public static (Shared in Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe.
