Blazor WebAssembly : "where" error in release mode

[Saeidasadi32]

I use where with string parameter and run correctly in debug mode.
but when i use release mode system has generate error

1. What does your code look like?
2. What is your predicate? In other words, what string are you passing in to Where?
3. What exception are you getting? Include the stack trace.
4. What is the shape of the objects you are querying?
5. Is it possible you are querying different objects in release mode?

[Saeidasadi32]

Thank you for your response1) I write this code : Freports = Freports.AsQueryable().Where(formula).OrderBy(x => x.PE).ToList();2) String (formula ) is : "(PE > 0.0) && (PE < 15.0 ) &&  (LST > 300.0)"3) exception in release mode: Operator 'and' incompatible with operand types 'Boolean' and 'Boolean'5) when run  'where' with just one statement like "(PE>0.0)" in release or debug mode system run correctly and no exception please help me!Thanks' againSaeid On Saturday, November 21, 2020, 10:29:26 PM GMT+3:30, Zev Spitz <[email protected]> wrote: - What does your code look like? - What is your predicate?

1. What is the compile-time type of Freports? IEnumerable? IEnumerable<Freport>?
2. What is at the ElementType property of Freports after the query, and before the ToList?
3. What is the shape of that type? public class ...

And you still haven't answered my previous question:

1. Is it possible you are querying different objects in release mode?

From what I can see, the syntax looks fine, and it should work in both Debug and Release mode.

1. I don't see the LST property/field in the definition you posted.
2. Again, is it possible the query is being run against different objects in release mode?
3. Are we talking about Preports? Or Freports?

Please try to use Markdown formatting for code and lists; it makes things much easier to read.

1. What framework are you targeting?
2. What version of Dynamic LINQ?
3. Which version of Visual Studio are you using, if any? Or, if you're using another editor, please specify.

[zspitz]

This is the code I am using to try and reproduce your exception; it works in both Debug and Release mode:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Linq.Dynamic.Core;

var formula = "(PE > 0.0) && (PE < 15.0 ) &&  (LST > 300.0)";
var FReports = new List<SReport>();
FReports = FReports.AsQueryable().Where(formula).OrderBy(x => x.PE).ToList();

foreach (var x in FReports) {
    Console.WriteLine(x);
}

public class SReport {
    public double PE { get; set; }
    public double LST { get; set; }
}

Using:

• Visual Studio 2019 (16.8.1)
• Targeting .NET 5
• Dynamic LINQ 1.2.5

I can't think of what else to try.

I've never used C# to generate WebAssembly. Can you post a sample project with code that reproduces this issue?

[Saeidasadi32]

Hi againI upload in Attachment very simple project.This sample work correctly in debug mode and generated error in release mode!Thanks https://drive.google.com/file/d/1TDheadz092FgMvxOj7MYY5Rd8dq_2txP/view?usp=drivesdk On Sunday, November 22, 2020, 12:39:26 AM GMT+3:30, Zev Spitz <[email protected]> wrote: I've never used C# to generate WebAssembly.

HiI myself try to Solving the Problem in System.Linq.Dynamic.Core in release mode.I replace all '&&' with '&' and run My project in release mode.In this Time no Error reported and ran correctly!Why!!

I replace all '&&' with '&'

That may be a different operation; it's interpreted as a bitwise AND, and may produce different results.

& also produces a logical AND when the two operands are boolean; see below.

OK. I can confirm the following:

• the && operator between two bools causes an exception when run in Release mode, but not in Debug mode.
• & works in both Debug and Release; the expression tree is still built correctly as a logical AND between two bools.
• Neither operand seems to be a bool?.
• The types of the two operands are equivalent -- expr.Left.Type == expr.Right.Type returns true

The following code also produces the same error only in Release mode, not in Debug mode:

    var prm = System.Linq.Expressions.Expression.Parameter(typeof(string));
    var selector = "true && false";
    var parser = new System.Linq.Dynamic.Core.Parser.ExpressionParser(new[] { prm }, selector, new object[] {}, System.Linq.Dynamic.Core.ParsingConfig.Default);
    var expr = parser.Parse(null);

Try the following:

1. Close Visual Studio
2. Delete the .vs folder in the root solution folder
3. Delete all the bin and obj folders
4. Reopen the solution

I did this and now && works in both Debug and Release mode.

Hello @Saeidasadi32,

See also this issue : #358

Your issue can be solved by adding this line to your Client WebAssembly project:

<BlazorWebAssemblyEnableLinking>false</BlazorWebAssemblyEnableLinking>

Or you can specify exactly what you want, see this link : https://docs.microsoft.com/en-us/aspnet/core/blazor/host-and-deploy/configure-linker?view=aspnetcore-3.1#control-linking-with-a-configuration-file

I applied this also to my example project here: BlazorAppHandlebarsExample

I probably have to add a Blazor WebAssembly section to the documentation to explain this scenario.
