I've implemented .NET Core 3.0 Preview 8 into my app, but now when I try to use App Center, I get this error message:

Is there any way to use .NET Core 3.0 Preview 8 with App Center Build?
App Center Build doesn't currently support preview versions of .NET Core, but we can manually install .NET Core 3.0 Preview 8 using a post-clone script.
Here's a walkthrough I put together on the topic: https://www.codetraveler.io/2019/08/23/using-preview-versions-of-net-core-with-app-center-build/
wget https://dot.net/v1/dotnet-install.sh
chmod +x dotnet-install.sh
./dotnet-install.sh --version "3.0.100-preview8-013656" --install-dir "$AGENT_TOOLSDIRECTORY/dotnet"
