I have problem with EF 6.2 and WPF application. When I try get data from DB (any collection) receives a message on Results View:
Expanding the Results View will enumerate the IEnumerable
when I expand next level message
The function evaluation requires all threads to run
when I click refresh icon message it's changing
Unable to evaluate the expression. Operation not supported. Unknown error: 0x80070057.
When I add .ToList()
at the end of query everything's working fine I can view the results of my query. My code working OK but when i debbunging I can't show my result - this is very useful.
I do not want to add .ToList()
for each my query because is part of big query.
