Fresh Template v7 Postgre Error

[Alik2015]

After installing fresh template using dotnet new idserver -o IdServer get exception when POSTGRE set.

System.TypeLoadException: 'Method 'get_LockReleaseBehavior' in type 'Npgsql.EntityFrameworkCore.PostgreSQL.Migrations.Internal.NpgsqlHistoryRepository' from assembly 'Npgsql.EntityFrameworkCore.PostgreSQL, Version=8.0.10.0, Culture=neutral, PublicKeyToken=5d8b90d52f46fda7' does not have an implementation.'
Previously was running version 6 and had it working.

Process used maybe wrong way but

1. Created new template from idserver using templates from github
2. Delete everything in older folder
3. Moved all files from new template into old folder and keep my appsettings.json to use postgres

This kind of exception generally occurs when there is a version mismatch between EF Core and the Npgsql package. By default, the SimpleIdServer template is configured to use:

 <PackageReference Include="Npgsql.EntityFrameworkCore.PostgreSQL" Version="8.0.10" />
 <PackageReference Include="Microsoft.EntityFrameworkCore.Design" Version="8.0.10">
   <PrivateAssets>all</PrivateAssets>
   <IncludeAssets>runtime; build; native; contentfiles; analyzers</IncludeAssets>
 </PackageReference>

Could you please check your .csproj file to ensure there is no version mismatch?

Can confirm csproj file of my idserver has

	  <PackageReference Include="Microsoft.EntityFrameworkCore.Design" Version="8.0.10">
		<PrivateAssets>all</PrivateAssets>
		<IncludeAssets>runtime; build; native; contentfiles; analyzers</IncludeAssets>
	  </PackageReference>
	  <PackageReference Include="Npgsql.EntityFrameworkCore.PostgreSQL" Version="8.0.10" />

Further update
Works when upgraded the posgres package to v10 but everything fails if IsRealm set to false in appsettings, wanted to use withtout realm, but happy to keep realm if disabling is a big issue for now.

I don’t know exactly what you’re trying to achieve, but the templates present in the master branch cannot be used (https://github.com/simpleidserver/SimpleIdServer/tree/master/src/Templates/templates/SimpleIdServer.IdServer.Startup
). They are used by our build server to publish the NuGet package.

If you want to use the latest version of SimpleIdServer.Server, please use the following source code instead:
https://github.com/simpleidserver/SimpleIdServer/tree/master/src/IdServer/SimpleIdServer.IdServer.Startup

When running this solution with PostgreSQL, everything works correctly:

• There is no need to upgrade the PostgreSQL package to version 10.
• There is no unexpected exception when the IsRealm property is set to false.
