Known issues
Some of the known issues available in Core 1.0 are the following:
  • EF Core: Some queries significantly slower when executed async 
  • EF Core: Pre-RTM migrations may need maxLength added to string columns 
  • EF Core: Commands on UWP projects require manually adding binding redirects .
The company states,
“It is also worth noting that the EF Core LINQ provider is still maturing. LINQ providers are complex and take time to mature, and EF Core in no exception. Improving our LINQ provider will be one of the main focuses of our upcoming releases. The majority of issues result in an exception when you attempt to execute a LINQ query that contains a particular pattern. There are often ways to workaround these issues by expressing the same query using different patterns, or evaluating parts of the query client-side. We try to include these workarounds in the issue, when they are available.”
