on GitHub

Major changes (since 2.0.0-beta3)

• New provider lifecycle model to replace the old one (#3738, #3887, #3946, #3927, #4000, #4026, #4022, #4045, #4031, #4047, #4063, #4042, #4064, #4066, #4067, )
• Builder pattern and options-based configuration of components and extensions (#3897, #3900, #3878, #3901, #3947, #3972, #3977, #3948, #3963, #3981, #4020, #4025, #4024, #4030, #4035, #4029, #4022, #4031, #4049, #4064, #4066, #4070, #4067, #4074)

Known issues

• AddMemoryGrainStorage() and AddMemoryGrainStorageAsDefault() do not ensure that OrleansProviders.dll is added and inspected for grain types. In a non-default case, when silo configuration code explicitly adds application assemblies (via ConfigureApplicationParts) but doesn't include OrleansProviders.dll in the list, the memory grain storage provider will not function. The workaround is to add OrleansProviders.dll to the list via ConfigureApplicationParts. The default case, when ConfigureApplicationParts isn't explicitly called and all assemblies in the silo folder are scanned, works as expeted.
