PS0084: Project Could Not Be Initialized


Severity	Error
Reported by	PostSharp
Message	`The project could not be initialized because of the previous errors.`

Cause

Before it processes an assembly, the PostSharp compiler sets up the project: it instantiates the services and the tasks that the configuration files, such as postsharp.config or a .psproj file, and the plug-ins define, and reads the attributes of each task. When the build has reported an error by the end of this setup, PostSharp reports PS0084, which stops the build.

PS0084 is a consequence: the cause is in the errors that PostSharp reports with it. The common ones come from a Tasks section of a configuration file:

PS0079: an element names a task that no plug-in defines.
PS0082: an element does not set an attribute that the task requires.
PS0075: the Compile element sets SignAssembly without a private key.

In the following example, the postsharp.config file next to the program configures a task that does not exist, so PostSharp reports PS0079 and then PS0084.

error PS0079: postsharp.config(5,6): The task "Minify" is not defined. Check the name of the element, or add the plug-in that defines the task.

Resolution

Fix the other errors of the build, starting with the first one, as the article of each message describes. PS0084 disappears with them. When the errors come from a Tasks section that you do not need, remove the section: PostSharp configures its tasks itself.

In the following example, the element of the undefined task is removed.
