ASP0000: Do not call 'IServiceCollection.BuildServiceProvider' in 'ConfigureServices'
| Value | |
|---|---|
| Rule ID | ASP0000 |
| Category | Usage |
| Fix is breaking or non-breaking | Non-breaking |
Cause
A call to BuildServiceProvider was detected in the application start up code.
Rule description
Calling 'BuildServiceProvider' from application code results in more than one copy of singleton services being created which might result in incorrect application behavior. Consider alternatives such as dependency injecting services as parameters to 'Configure'.
How to fix violations
Remove the call to BuildServiceProvider from the application startup code.
When to suppress warnings
It is safe to suppress this rule if updating the application to remove the call to BuildServiceProvider is non-trivial and you have thoroughly tested the application to ensure multiple singleton services are not added.
