You will need to use the Sql(string) method to perform some of these steps.

Table rebuilds involve creating a new table, copying data to the new table, dropping the old table, renaming the new table.

All SQL commands supported by SQLite (for limitations, see SQLite help page: SQL As.

You can work around some of these limitations by manually writing code in your migrations to perform a rebuild. GRASS is automatically creating the SQLite database if it is not yet. Rebuilds are only possible for database artifacts that are part of your EF Core model. The SQLite database engine does not support the following schema operations that are supported by the majority of other relational databases.

The SQLite provider does not support schemas and Sequences.

And yes, there is a SQLITEMAXVARIABLENUMBER host parameter set to 999 which prevents excessive memory.

A rebuild will be attempted to perform certain operations. Actually, we knew that we need to visit sqlite site and took a look at Limitations page.

If you attempt to apply one of the unsupported operations to an SQLite database then a NotSupportedException will be thrown.

The SQLite database engine does not support many schema operations that are supported by the majority of other relational databases.

You can use a value converter to continue using decimal in your classes.

If you don't need that level of precision, however, it is recommended to use double instead.

The Decimal type provides a high level of precision.

When handling multiple time zones, It is recommended to convert the values to UTC before saving and then converting back to the appropriate time zone.

Instead of DateTimeOffset, it is recommended to use DateTime values. The SQLite team is committed to supporting System.Data.

Development and maintenance work is now mostly performed by the SQLite Development Team. Other operations, however, like comparison and ordering will require evaluation on the client. Robert still has commit privileges on this repository but is no longer an active contributor. EF Core can read and write values of these types, and querying for equality ( where e.Property = value) is also supported. SQLite doesn't natively support the following data types. A couple of these concepts are not supported by the SQLite provider. The common relational library (shared by Entity Framework relational database providers) defines APIs for modeling concepts that are common to most relational database engines. The SQLite provider has several migration limitations and most of these limitations are a result of limitations in the underlying SQLite database engine and are not specific to EF.
