The version exists, but the pipeline cannot see it. Check the build identity's feed role, the feed view in the URL, which nuget.config the task uses, package source mapping, and the 30-minute HTTP cache.

MudBlazor 9.12.0 fixes a long-standing race in MudAutocomplete, MudDataGrid and MudTable: the result of the search that finished last used to win, not the one started last. Here is how the fix works and what changes for your ServerData and SearchFunc code.

Return bool from a TryX method when failure is an ordinary outcome the caller will branch on, and throw when it is a bug or a broken precondition. Measured on .NET 10.0.10: a failed int.TryParse costs 4.9 ns, a caught FormatException costs 2,487 ns.

Code resolved a service from a DI scope or root provider after it was disposed. Capture IServiceScopeFactory instead of IServiceProvider and create a fresh scope where the work runs.

CS8618 is checked when the constructor exits, and [MemberNotNull] on a static method is silently ignored for instance members. Pass the values into a private constructor instead.

The Set-Cookie header is sent, but the browser rejects or never stores it. Fix SameSite=None without Secure, missing credentials: 'include' plus AllowCredentials, consent policy, and late Append calls.

Infragistics open-sourced more than 50 Ignite UI for Blazor controls under MIT, shipped as IgniteUI.Blazor.Lite and IgniteUI.Blazor.GridLite 1.0.0 for net8.0, net9.0 and net10.0. Here is what is free, how to wire it up, and the gotchas.

EF Core never updates a key value on a tracked entity. Stop copying the key from DTOs, use a unique index instead of an alternate key, and change a real key by inserting a new row and deleting the old one. Tested on EF Core 10.0.14.

Enumerable.Zip allocates 144-208 bytes per call and runs about 10x slower than a plain loop. For arrays and lists, a for loop over two spans sliced to the same length is allocation-free and the fastest option; for foreach syntax, a small ref struct zip enumerator gets within 25% of it. Measured on .NET 10.0.10 and .NET 11 RC 3.

Polly.Core 8.8.1 starts the circuit breaker's background loop under ExecutionContext.SuppressFlow, so a long-lived pipeline stops pinning the AsyncLocal values of whoever built it. A 15-line repro shows the leak on 8.8.0 and the fix on 8.8.1.
