This post is not valid anymore. The Episerver Templates are automatically .net6 or later after may 2022. Anyhow, it shows how to update .net version on a solution.

Easy install with “dotnet new”

Open command prompt in new directory

Install the Optimizely .net Templates:

dotnet new install EPiServer.Templates

Install the the Alloy .net5 Template:
(out of the box the template is .net5 – at time writing)

dotnet new epi-alloy-mvc --name Epicweb.AlloyDot.Net6

cmd prompt output

Now upgrade to .net6

notepad Epicweb.Alloy.Net6.csproj

replace <TargetFramework>net5.0</TargetFramework>
with <TargetFramework>net6.0</TargetFramework>

replace <PackageReference Include=”EPiServer.CMS” Version=”12.3.0″ /> 


<PackageReference Include="EPiServer.CMS" Version="12.4.0" />
<PackageReference Include="EPiServer.CloudPlatform.Cms" Version="1.0.4" />
<!-- Extra top level dependencies needed to force CMS 6 compatible version of CMS Core -->
<PackageReference Include="EPiServer.CMS.AspNetCore.HtmlHelpers" Version="12.5.0" />
<PackageReference Include="EPiServer.Hosting" Version="12.5.0" />
<!-- Extra top level dependencies needed until our CloudPlatform and AspnetIdentity packages are updated to declare .NET 6 dependencies -->
<PackageReference Include="Microsoft.AspNetCore.Mvc.Razor.Extensions" Version="6.0.0" />
<PackageReference Include="Microsoft.EntityFrameworkCore.SqlServer" Version="6.0.2" />
<PackageReference Include="Microsoft.Extensions.Hosting.Abstractions" Version="6.0.0" />
<PackageReference Include="Microsoft.Extensions.Configuration.Abstractions" Version="6.0.0" />
<PackageReference Include="Microsoft.Extensions.Options" Version="6.0.0" />

Above forces to use .net6 assemblies, read more here and here
