MSSQL 2014: Could not open referenced table

Microsoft.SQLServer.2014.Could_not_open_referenced_table_1_5_Rule (Rule)

You are trying to add, drop, or modify a constraint on a table that has a schema stability lock (LCK_M_SCH_S or Sch-S) held on it. The schema stability lock is not compatible with DDL. The lock may be held by a query involving this table that is taking a long time to compile.
