 3 | # ContosoUniversity on ASP.NET Core 6.0 on .NET 6 and Razor Pages
 4 | 
 5 | Contoso University, the way I would write it.
 6 | 
 7 | This example requires some tools and PowerShell modules, you should run `setup.cmd` or `setup.ps1` to install them.
 8 | 
 9 | To prepare the database, execute the build script using [PSake](https://psake.readthedocs.io/): `psake migrate`. Open the solution and run!
10 | 
11 | ## Things demonstrated
12 | 
13 | - CQRS and MediatR
14 | - AutoMapper
15 | - Vertical slice architecture
16 | - Razor Pages
17 | - Fluent Validation
18 | - HtmlTags
19 | - Entity Framework Core
20 | 
21 | ## Migrating the Database
22 | 
23 | Grate will automatically create or upgrade (migrate) the database to the latest schema version when you run it:
24 | 
25 | From PowerShell:
26 | ```
27 | invoke-psake migrate
28 | ```
29 | 
30 | From CMD:
31 | ```
32 | psake migrate
33 | ```
34 | 
35 | When running unit tests, you can recreate the unit test database using:
36 | 
37 | ```
38 | invoke-psake migratetest
39 | ```
40 | 
41 | ## Versioning
42 | 
43 | Version numbers can be passed on the build script command line:
44 | 
45 | From PowerShell:
46 | ```
47 | invoke-psake CI -properties ${'version':'1.2.3-dev.5'}
48 | ```
49 | 
50 | Because we're passing a PowerShell dictionary on the command line, the cmd script doesn't handle this very nicely.
51 | 
52 | Or generate a version using [GitVersion](https://gitversion.net/docs/) locally:
53 | ```
54 | psake localversion
55 | ```
56 | will generate a semantic version and output it.
