During creating my first page I noticed that I could not run .Net from cmd. I do not know what exactly is a problem. I am sending you a command lines.

I checked some website's solutions. None from this solutions helped me.

The error is quite clear at the top of the stack trace you posted, although these big error messages can be hard to read sometimes:

fail: Microsoft.EntityFrameworkCore.Database.Command[20102]
      Failed executing DbCommand (133ms) [Parameters=[@__normalizedEmail_0='?' (Size = 256)], CommandType='Text', CommandTimeout='30']
      SELECT TOP(1) [u].[Id], [u].[AccessFailedCount], [u].[ConcurrencyStamp], [u].[Email], [u].[EmailConfirmed], [u].[FirstName], [u].[LastName], [u].[LockoutEnabled], [u].[LockoutEnd], [u].[NormalizedEmail], [u].[NormalizedUserName], [u].[PasswordHash], [u].[PhoneNumber], [u].[PhoneNumberConfirmed], [u].[SecurityStamp], [u].[TwoFactorEnabled], [u].[UserName]
      FROM [AspNetUsers] AS [u]
      WHERE [u].[NormalizedEmail] = @__normalizedEmail_0
System.Data.SqlClient.SqlException (0x80131904): Invalid object name 'AspNetUsers'.

So the system is trying to run the query:

 SELECT TOP(1) [u].[Id], [u].[AccessFailedCount], [u].[ConcurrencyStamp], [u].[Email], [u].[EmailConfirmed], [u].[FirstName], [u].[LastName], [u].[LockoutEnabled], [u].[LockoutEnd], [u].[NormalizedEmail], [u].[NormalizedUserName], [u].[PasswordHash], [u].[PhoneNumber], [u].[PhoneNumberConfirmed], [u].[SecurityStamp], [u].[TwoFactorEnabled], [u].[UserName]
      FROM [AspNetUsers] AS [u]
      WHERE [u].[NormalizedEmail] = @__normalizedEmail_0

And is getting the error:

System.Data.SqlClient.SqlException (0x80131904): Invalid object name 'AspNetUsers'.

You should check that the table exists and that the user account you are using has access to the table. You could even try running the query yourself from SQL Management Studio to see what happens

Thanks for your quick answer but still i really do not know what to do
@Drax - Your query is attempting to access a table called "AspNetUsers" which doesn't seem to exist. Are you sure the connection string is pointing to a database that has a table with that name? Perhaps your entity for that table is not correct. It's difficult to say since you did not provide any code.
I came through the same issue, In my case i deleted the Snapshot File that gets auto generated while creating the Migration . It resolved my issue
I also got a Failed executing DbCommand, yet the SQL command itself was fine. I finally resolved it by comparing every change since the last commit and finding <Nullable>annotations</Nullable> had appeared in the .csproj file in the top <PropertyGroup>. Removing this line fixed the problem. Why? Where did it come from? No idea.
