✅ I cannot create a database

It occurs when i try to run my website project or do "add-migration" to create a database.

MissingMethodException: Method not found: 'Microsoft.EntityFrameworkCore.Metadata.Builders.IndexBuilder`1<!!0> Microsoft.EntityFrameworkCore.RelationalIndexBuilderExtensions.HasName(Microsoft.EntityFrameworkCore.Metadata.Builders.IndexBuilder`1<!!0>, System.String)'.

Microsoft.AspNetCore.Identity.EntityFrameworkCore.IdentityUserContext<TUser, TKey, TUserClaim, TUserLogin, TUserToken>+<>c__DisplayClass20_0.<OnModelCreating>b__0(EntityTypeBuilder<TUser> b)

MissingMethodException: Method not found: 'Microsoft.EntityFrameworkCore.Metadata.Builders.IndexBuilder`1<!!0> Microsoft.EntityFrameworkCore.RelationalIndexBuilderExtensions.HasName(Microsoft.EntityFrameworkCore.Metadata.Builders.IndexBuilder`1<!!0>, System.String)'.

Microsoft.AspNetCore.Identity.EntityFrameworkCore.IdentityUserContext<TUser, TKey, TUserClaim, TUserLogin, TUserToken>+<>c__DisplayClass20_0.<OnModelCreating>b__0(EntityTypeBuilder<TUser> b)

make sure everything is the same version, and that there are no warnings

no real warnings that affect the code it seems only some mutable nullable warnings can it be cross project incompatiblity? it was that smh i always forget that this time i didnt see a lib was depreciated at 3.0.5 ty

but still there should be a warning for this

StickyOP•5mo ago

it was depricated but i downloaded 8.x versions of helper libs for it so i guess that was the issue no errors were there
