Setting IdentityUIFrameworkVersion>Bootstrap4</IdentityUIFrameworkVersion

[alexisconsuegra]

First suggested method: Adding <IdentityUIFrameworkVersion>Bootstrap4</IdentityUIFrameworkVersion> to PropertyGroup did not solved the problem. Is there anything missing in this aproach? Migrating to Boostrap 5 is not possible at this time. Thanks

@haok or @Rick-Anderson Can you help with this issue?

[Rick-Anderson]

First suggested method: Adding Bootstrap4 to PropertyGroup did not solved the problem.

Can you create the simplest possible repo that demonstrates this problem? Create a RP o MV app with individual user accounts using the 5.0 templates. Add

<PropertyGroup>
  <TargetFramework>net6.0</TargetFramework>
  <IdentityUIFrameworkVersion>Bootstrap4</IdentityUIFrameworkVersion>
</PropertyGroup>

Also did you scaffold out any/all of the identity UI pages?

[alexisconsuegra]

Hi, The article did not mention the need to scaffold out any/all of the identity UI pages, did it? Can you elaborate here? But in my case this was a NET 5 project. The identity UI pages were scaffolded using the 5 templates (That's why the Boostrap version is 4). On top of that all the UI pages have been worked on to show a real app looked. Re-scaffolding them means recreating the pages again.

[HaoK]

After setting the property to boostrap4, can you double check via F12 on one of your identity pages, after forcing a reload of all the resources, that the bootstrap assets you are getting from identity ui are bootstrap 5 or 4?

[alexisconsuegra]

Hi Haok, The application does not start: Unhandled exception. Here is the error. System.InvalidOperationException: Found an invalid value for the 'IdentityUIFrameworkVersion'. Valid values are 'Bootstrap4', 'Bootstrap3' at Microsoft.AspNetCore.Identity.IdentityBuilderUIExtensions.TryResolveUIFramework(Assembly assembly, UIFramework& uiFramework) at Microsoft.AspNetCore.Identity.IdentityBuilderUIExtensions.<>c__DisplayClass2_0.<AddRelatedParts>b__0(ApplicationPartManager partManager) at Microsoft.Extensions.DependencyInjection.MvcCoreMvcBuilderExtensions.ConfigureApplicationPartManager(IMvcBuilder builder, Action`1 setupAction)

Here is the project file used to build it:

`<Project Sdk="Microsoft.NET.Sdk.Web">

net6.0 Bootstrap4 aspnet-MyTest-x...x all runtime; build; native; contentfiles; analyzers; buildtransitive `

[alexisconsuegra]

<Project Sdk="Microsoft.NET.Sdk.Web"> <PropertyGroup> <TargetFramework>net6.0 </TargetFramework> <IdentityUIFrameworkVersion>Bootstrap4 </IdentityUIFrameworkVersion> <UserSecretsId>aspnet-MyTest-x...x </UserSecretsId> </PropertyGroup> <ItemGroup> <PackageReference Include="Microsoft.AspNetCore.Diagnostics.EntityFrameworkCore" Version="6.0.7" /> <PackageReference Include="Microsoft.AspNetCore.Identity.EntityFrameworkCore" Version="6.0.7" /> <PackageReference Include="Microsoft.AspNetCore.Identity.UI" Version="6.0.7" /> <PackageReference Include="Microsoft.EntityFrameworkCore.Sqlite" Version="6.0.7" /> <PackageReference Include="Microsoft.EntityFrameworkCore.SqlServer" Version="6.0.7" /> <PackageReference Include="Microsoft.EntityFrameworkCore.Tools" Version="6.0.7"> <PrivateAssets>all </PrivateAssets> <IncludeAssets>runtime; build; native; contentfiles; analyzers; buildtransitive </IncludeAssets> </PackageReference> <PackageReference Include="Microsoft.VisualStudio.Web.CodeGeneration.Design" Version="6.0.7" /> </ItemGroup> <ItemGroup> <Folder Include="Extensions\" /> </ItemGroup> </Project>

That error message seems to point at the problem, are you sure you are running against 6.0? It should only support Bootstrap5 and Bootstrap4

[HaoK]

That said, we only guarantee this works against the non scaffolded identity UI, if you replaced/scaffolded pages, you should be able to directly update your links in your pages, and point back to boostrap4 on any pages you scaffolded out

[alexisconsuegra]

Hi Haok, In regards to your first question: Wouldn't the following line guarantee it is running against 6.0? <Project Sdk="Microsoft.NET.Sdk.Web"> <PropertyGroup> <TargetFramework>net6.0 </TargetFramework> Second questions. I will try to answer: The identity UI pages were originally scaffolded using the core 5 templates. I updated the target framework and packages to version 6. UI pages were not re-scaffolded again. I hope this helps understand.

Can you create a repro project and upload it to a git so I can see the behavior for myself and investigate?

Create the simplest possible project.

[alexisconsuegra]

Hi Yes, let me have a simple project. FYI. It works in my local host, but it throws the error at my hosted enviroment. I have confirmed core 6 is installed.

[bcons009]

Hi. This is the simple repo with @alexisconsuegra 's issue: https://github.com/bcons009/netcore-demo5

[alexisconsuegra]

Hi @Rick-Anderson Have you been able to check the repo Bryan created for this issue?

[Rick-Anderson]

@alexisconsuegra I create an ASP.NET Core MVC project with individual user accounts using .NET 5, then I updated the project settings with the following:

	<PropertyGroup>
		<TargetFramework>net6.0</TargetFramework>
		<IdentityUIFrameworkVersion>Bootstrap4</IdentityUIFrameworkVersion>
		<UserSecretsId>aspnet-WebApplication1-66EF50D6-BDA8-4633-8B19-2CB038E9DA15</UserSecretsId>
	</PropertyGroup>

And it worked as expected. F12 tools shows it's using Bootstrap4

[alexisconsuegra]

I guess the work around only works in localhost. FYI. Locally works for me too, but not in the hosted enviroment.

[Rick-Anderson]

https://webbootstrap44.azurewebsites.net/ Works fine deployed too.
