MissingManifestResourceException Class

[ This article is for Windows Phone 8 developers. If you’re developing for Windows 10, see the latest documentation. ]

The exception thrown if the main assembly does not contain the resources for the neutral culture, and they are required because of a missing appropriate satellite assembly.

The MissingManifestResourceException type exposes the following members.


Name Description
MissingManifestResourceException()()() Initializes a new instance of the MissingManifestResourceException class with default properties.
MissingManifestResourceException(String) Initializes a new instance of the MissingManifestResourceException class with the specified error message.
MissingManifestResourceException(String, Exception) Initializes a new instance of the MissingManifestResourceException class with a specified error message and a reference to the inner exception that is the cause of this exception.



Name Description
Data Gets a collection of key/value pairs that provide additional user-defined information about the exception. (Inherited from Exception.)
HelpLink Gets or sets a link to the help file associated with this exception. (Inherited from Exception.)
HResult Gets or sets HRESULT, a coded numerical value that is assigned to a specific exception. (Inherited from Exception.)
InnerException Gets the Exception instance that caused the current exception. (Inherited from Exception.)
Message Gets a message that describes the current exception. (Inherited from Exception.)
Source Gets or sets the name of the application or the object that causes the error. (Inherited from Exception.)
StackTrace Gets a string representation of the frames on the call stack at the time the current exception was thrown. (Inherited from Exception.)



Name Description
Equals(Object) Determines whether the specified Object is equal to the current Object. (Inherited from Object.)
Finalize Allows an object to try to free resources and perform other cleanup operations before the Object is reclaimed by garbage collection. (Inherited from Object.)
GetBaseException When overridden in a derived class, returns the Exception that is the root cause of one or more subsequent exceptions. (Inherited from Exception.)
GetHashCode Serves as a hash function for a particular type. (Inherited from Object.)
GetType Gets the runtime type of the current instance. (Inherited from Exception.)
MemberwiseClone Creates a shallow copy of the current Object. (Inherited from Object.)
ToString Creates and returns a string representation of the current exception. (Inherited from Exception.)



A MissingManifestResourceException is thrown when the attempt to retrieve a resource fails because the resource set for the neutral culture could not be loaded from a particular assembly. Note that even though the exception is thrown when you attempt to retrieve a particular resource, it is caused by the failure to load the resource set rather than the failure to find the resource. The main causes of the exception include the following:

  • The resource set is not identified by its fully qualified name. For example, if the baseName parameter in the call to the ResourceManager..::.ResourceManager(String, Assembly) method includes the root name of the resource set without a namespace, but the resource set is assigned a namespace when it is stored in its assembly, the call to the ResourceManager..::.GetStringmethod throws this exception. You can determine the namespace of the resource set by examining its assembly with a reflection tool such as Ildasm.exe.

  • The resource set is identified by its resource file name and its file extension. For example, this exception is thrown if the neutral culture's resource set is named GlobalResources and you supply a value of "GlobalResources.resources" to the baseName parameter of the ResourceManager..::.ResourceManager(String, Assembly) constructor.

  • The culture-specific resource set identified in a method call cannot be found, and the fallback resource set cannot be loaded. For example, if you create satellite assemblies for the English (United States) and Russia (Russian) cultures but you fail to provide a resource set for the neutral culture, this exception is thrown if your application's current culture is English (Great Britain).

For a list of initial property values for an instance of MissingManifestResourceException, see the MissingManifestResourceException constructors.


We strongly recommend that your main assembly contain a neutral set of resources, so if a satellite assembly is unavailable, your application will not fail.
