When using EF Core migrations to manage your database schema, the following configures the column for the Name property to be case-insensitive in a database that is otherwise configured to be case-sensitive: In some cases, the same column needs to be queried using different collations by different queries. Case insensitive regular expression without re.compile? Although database systems usually do permit altering the collation of an existing database, doing so can lead to complications; it is recommended to pick a collation before database creation. In addition, .NET provides overloads of string.Equals accepting a StringComparison enum, which allows specifying case-sensitivity and a culture for the comparison. Specifying an explicit collation in a query will generally prevent that query from using an index defined on that column, since the collations would no longer match; it is therefore recommended to exercise caution when using this feature.
