Fix: framework_version=6.0.0 was not found when launching a .NET 6 binary
The .NET 6 runtime is gone or mismatched. Either install net6.0 again, roll forward to net8.0 via runtimeconfig, retarget the csproj, or ship self-contained.
dotnet new mcpserver Now Ships in the .NET 11 Preview 4 SDK
.NET 11 Preview 4 bundles the mcpserver project template directly into the SDK. No separate Microsoft.McpServer.ProjectTemplates install, no preview feed dance. Pick stdio or HTTP transport, opt into Native AOT, and dotnet new mcpserver -o MyServer is the whole setup.
Fix: Provisioning profile doesn't include the currently selected device in MAUI iOS
The profile Visual Studio picked was generated before this iPhone's UDID was registered. Re-register the device, regenerate the development profile, redownload, redeploy.
Fix: Unable to find a valid iOS Simulator runtime during MAUI build
Xcode 15+ ships without bundled iOS simulator runtimes. MAUI fails the build when SupportedOSPlatformVersion has no matching runtime installed. Install one with xcodebuild -downloadPlatform iOS or via Xcode Settings, then verify with xcrun simctl list runtimes.

Fix: A possible object cycle was detected
System.Text.Json refuses to serialize graphs with back-references. Set ReferenceHandler.IgnoreCycles, project to a DTO, or mark the back-pointer with [JsonIgnore]. Preserve is a last resort.
Fix: SqlException: Timeout expired during EF Core migrations
Migrations use the design-time DbContext, not your runtime CommandTimeout. Set the timeout via UseSqlServer(o => o.CommandTimeout(...)), the connection string Command Timeout, or Database.SetCommandTimeout before Migrate().
Fix: System.Text.Json.JsonException: The JSON value could not be converted
System.Text.Json throws this when the incoming JSON token doesn't match the CLR target type. Match the JSON to the type, or register a JsonConverter or JsonSerializerOption that bridges them.
