Helpful MediatR pipelines.

• Authorization
• Caching
• Validation
• Localization
• Logging

The Authorization behavior uses an IAuthorizationService to determine whether the current user has permission to access the response.

You must provide an AuthorizationPolicy, a policy name (a string), an IEnumerable<IAuthorizationRequirement> or a single IAuthoizationRequirement to authorize against.

PM> Install-Package MediatR.Pipelines.Authorization

The caching behavior will cache the response using an IMemoryCache. Requests must implement the IIdempotentRequest interface and responses will only be cached if the CaheKey property on the request is not null.

PM> Install-Package MediatR.Pipelines.Caching

The validation behavior uses FluentValidation to validate the request. If a request is not valid then a ValidationException is thrown.

PM> Install-Package MediatR.Pipelines.FluentValidation

The localization behavior scans the response, looking for settable string properties decorated with a LocalizeAttribute. It will then get the localized string and inject it into that property.

PM> Install-Package MediatR.Pipelines.Localization

The logging behavior will log any exceptions thrown previously in the pipeline.

PM> Install-Package MediatR.Pipelines.Logging
