Create an empty file migration in Illegal character filename in add-migration

[Ali-YousefiTelori]

When you try to run this command in your Package Manager Console you will get the error to add immigration but you will see the empty file created in your migration folder:

add-migration "to fix error: add column is_deleted"

However, I cannot find commands of add-migration in ef core sources so I cannot fix this bug. if you guys tell me where is source of ef core design or tools maybe we can develop it.
Thank you

@Ali-YousefiTelori Can you provide an example of using a illegal character and give more details on the empty file created?

[Ali-YousefiTelori]

@ajcvickers you do not need an example, you can run that command in every project that will create an empty file in the migration folder

add-migration "to fix error: add column is_deleted"

@bricelam Confirmed empty file is created, for this example with name "20210202212632_to fix error".
