Hi @mkArtakMSFT, could you please take a look at this issue and help triage it? In the meantime, could you confirm if this a blocker for .NET 10 Preview1? Thanks.

I'm also running into this issue when trying to use the .NET 10 SDK nightly Docker image (mcr.microsoft.com/dotnet/nightly/sdk:10.0-preview) to build an ASP.NET Core 9 application to avoid the massive build slowdowns caused by .NET 9. This was recommended by @javiercn in this thread,

My project uses ASP.NET Core Identity for auth and I get the following errors:

It'll be really helpful to have a fix for this, as at the moment we're stuck with painfully long build times for our production applications and no obvious solution...

Edit - for completeness, here's my Dockerfile:

# This stage is used when running from VS in fast mode (Default for Debug configuration)

# This stage is used to build the service project
FROM mcr.microsoft.com/dotnet/nightly/sdk:10.0-preview AS build
ARG BUILD_CONFIGURATION=Release
WORKDIR /src

# First, copy just the csproj files so we can restore the dependencies.
# This will allow us to cache the dependencies and not have to restore them every time we change the source code.
COPY ["Directory.Packages.props", "."]
COPY ["Directory.Build.props", "."]
COPY ["ApiGateway.ApiService/ApiGateway.ApiService.csproj", "ApiGateway.ApiService/"]
# Redacted - copy other csproj files

# Then copy the remaining source code files
COPY . .
WORKDIR "/src/ApiGateway.ApiService"
RUN dotnet build "./ApiGateway.ApiService.csproj" -c $BUILD_CONFIGURATION -o /app/build

@mkArtakMSFT @danroth27 I saw that it was added to the 10.0-preview2 milestone. However, I didn't see any related PR links tracking the fix here. Could you please confirm if this is a blocker for .NET 10 Preview2 ?

[danroth27]

Adding @joperezr who now owns this area. Also adding @lewing since @javiercn is currently assigned.

[Junjun-zhao]

Hi @joperezr, could you please share any update or schedule for this issue? Thanks.

[joperezr]

I don't think this is being currently tracked as blocking for 10.0 Preview 2. @javiercn said he would take a look to triage this appropriately.

[funkysi1701]

Any update on this? I have just tried with 10.0 Preview 2 and it looks to still be an issue?

[javiercn]

I'm taking a look at this today
