TL;DR: Senior .NET developers from Asia cost $2,800-$6,500 a month through Second Talent, matched in 24 hours. The closest US benchmark, the BLS median for software developers, was $135,980 a year in May 2025.
Microsoft ends support for .NET 8 and .NET 9 on the same day, 10 November 2026, per its .NET support policy. Azure Functions apps on the in-process model lose support that day too. A .NET developer you hire this quarter can expect to spend the first weeks moving production code to .NET 10, the current long-term support release.
Key takeaways
- On our .NET developer rate cards, pay for work with international clients starts at $1,200 a month in Indonesia and reaches $7,530+ in India.
- C# was used by 29.9% of professional developers in Stack Overflow's 2025 survey, ahead of Java at 29.6%.
- Microsoft rated the October 2025 Kestrel request smuggling flaw CVSS 9.9, and self-contained apps had to be rebuilt to get the fix.
- Since .NET 9, BinaryFormatter throws an exception at runtime, which breaks older code during an upgrade.
What .NET Developers Earn Working for International Clients in Asia
India shows the widest range, from $1,880 to $7,530+ a month, while the Philippine card has the lowest ceiling in the table. The figure is what .NET developers in each market earn working directly for foreign companies, before any employer or platform costs.

Monthly ranges from the Remote (Working for International Clients) figures on our rate cards for Indonesia, the Philippines, Vietnam, India, Malaysia and Thailand, converted at ExchangeRate-API mid-market rates for 14 September 2026.
The Indonesia and Vietnam cards quote US dollars with a fixed top, so those rows need no conversion. The other four quote local currency and leave the top open. Malaysia and Thailand start within $20 of each other.
Through Second Talent, senior .NET developers cost $2,800-$6,500 a month: one monthly fee that bundles salary, payroll taxes, statutory contributions and our service fee. Our pricing page explains the subscription. For market-level detail we also publish guides to hiring .NET developers in Vietnam and Thailand.
US Pay Benchmark for .NET Developers
BLS has no .NET occupation. The role maps to Software Developers (SOC 15-1252), because a .NET developer designs and builds application software, from ASP.NET Core APIs to Windows desktop tools.
| BLS OEWS, May 2025, national |

Monthly figures are the annual wages on the OEWS profile for 15-1252 divided by 12, rounded to the nearest $10.
Salary is only part of the US cost. In the BLS Employer Costs for Employee Compensation release for June 2026, wages and salaries made up 68.5% of employer compensation costs for full-time private industry workers, and benefits the other 31.5%.
On the contract side, our C# and .NET developer cost-to-hire page puts a mid-level US freelance or contract C# developer at $85 to $135 an hour, before payroll, insurance and leave.
Time Zone Overlap with ET, CT and PT
Microsoft ships .NET patches on Patch Tuesday, the second Tuesday of the month, when there is a release. Its Windows monthly security release goes out at around 10:00 am Pacific that day. On 13 October 2026, the next Patch Tuesday, that is 17:00 UTC, or 1:00 am on Wednesday in Manila, so a developer there can patch and redeploy before your US team starts work.
Asian cities keep one offset all year, and US daylight time runs from 8 March to 1 November 2026, per NIST.

After 1 November 2026, every time in the table moves one hour later.
The 10 November end of support falls after that change. 10:00 am PST is 18:00 UTC, which makes it 2:00 am on Wednesday 11 November in Manila and 1:00 am in Ho Chi Minh City.
For code reviews and pairing on a migration, a Manila shift from 5:00 pm to 2:00 am runs 09:00 to 18:00 UTC. While daylight time lasts, that is 5:00 am to 2:00 pm in New York: five hours of a 9-to-5 day, four with Chicago and two with San Francisco.
We agree a schedule like this before the offer, which is how our placements get 4-6 hours of daily overlap with US hours.
That shift carries a cost for employees. Philippine law adds at least 10% for work between 10 pm and 6 am (Labor Code Article 86), four hours of it here. Vietnam sets at least 30% for work between 22:00 and 06:00 (Labor Code Articles 98 and 106).
.NET Developer Skills to Screen For
Among professional developers in Stack Overflow's 2025 survey, 21.3% worked in ASP.NET Core and 15% still worked in the older ASP.NET. Blazor was at 7.6%. A hire who takes over an older estate will meet code from both generations, so screen for the move between them.
Moving production apps to .NET 10
Microsoft released .NET 10 on 11 November 2025 and supports it until 14 November 2028. Even-numbered releases get three years of support and odd-numbered ones two, so .NET 11, a release candidate since 8 September 2026, is not LTS. Ask which release the candidate would pick for a .NET 8 app, and why.
Azure Functions on the isolated worker model
Microsoft's migration guide says support for the in-process model ends on 10 November 2026, and in-process apps on runtime 4.x target .NET 8. In the isolated worker model your functions run in a separate process from the host, so the assemblies your app loads no longer conflict with the host's versions. Microsoft Azure was used by 27.2% of professional developers in the Stack Overflow survey. Give an Azure candidate an in-process HTTP trigger and ask for the migrated version.
.NET Framework and Web Forms code
Microsoft's Blazor guide for Web Forms developers expects ASP.NET Web Forms to remain Windows-only, and calls it a supported framework as long as .NET Framework ships as part of Windows. The .NET Framework lifecycle page lists January 2027 as the end date for version 4.6.2. Ask for a Web Forms page the candidate rebuilt, and what they did with ViewState and session data.
Serialization breaks during upgrades
Starting with .NET 9, the runtime has no working BinaryFormatter. The APIs remain, but Microsoft's migration guide says they throw a PlatformNotSupportedException regardless of project type. Microsoft offers a compatibility package that restores it, without support and with the same security risks. Show the candidate a session cache that stores BinaryFormatter output and ask for a replacement plus a plan for the data already stored.
Patching Kestrel and self-contained apps
CVE-2025-55315, a request smuggling flaw in Kestrel, carried a CVSS score of 9.9, and Microsoft's MSRC explainer tied the score to its effect on authentication and authorization. The fix shipped on 14 October 2025 in ASP.NET Core 8.0.21 and 9.0.10. Microsoft's advisory adds that teams with self-contained apps built on an affected version must recompile and redeploy them. Ask how the candidate finds self-contained deployments in a fleet, since a runtime update on the server does not reach them.
Migration work with AI agents
Microsoft has deprecated the .NET Upgrade Assistant and points developers to the GitHub Copilot modernization agent in Visual Studio, per its Upgrade Assistant page. The agent writes a migration plan and commits each change. Among developers in Stack Overflow's AI survey, 66% named AI solutions that are almost right as a frustration. Ask the candidate to review an agent-generated upgrade commit and find what it got wrong.
Contractor or Employer of Record for a US Company
Software is not one of the nine categories of commissioned work that can be "work made for hire" under 17 U.S.C. § 101. A transfer of the copyright must be in writing and signed, under § 204(a). Name the solution, the NuGet packages the developer publishes for you and any migration scripts in the assignment.
IRS Publication 515 says the place where services are performed determines the source of the income, so a developer working from Jakarta or Bengaluru earns foreign-source income. A foreign individual gives the payer Form W-8BEN to certify foreign status.
Local law runs its own test. Philippine courts apply the four-fold test, and in Atok Big Wedge v. Gison the Supreme Court named the power of control as the most important part of it. Under Article 13 of Vietnam's 2019 Labor Code, an agreement under another name counts as a labor contract when it covers a paid job, wages and one party's management or supervision.
A fixed-scope port of one Web Forms app to Blazor fits a contractor agreement. A developer who joins your sprints, holds Azure subscription access and patches production each month fits both tests above, and an Employer of Record employs that developer in-country for you. Our EOR, PEO and contractor comparison sets out the trade-offs. This is a summary, not legal advice.

English Level and Working Norms
Enterprise .NET work produces written English that outlives the project: pull request descriptions, migration runbooks and the ticket history an auditor reads later. Malaysia ranks 24th of 123 countries and regions on the EF English Proficiency Index 2025, and Thailand 116th, against a global average of 488.

Scores come from EF's country pages, such as the Philippines and Thailand. Thailand's IT job-function score sits 57 points above its national score. Ask finalists to write the upgrade note for one breaking change, in the form your team would file it.
Plan releases around both calendars. Thanksgiving on 26 November 2026 is a working day in Asia, so a developer there can run a post-upgrade smoke test while your US office shuts for the holiday.
Article 112 of Vietnam's Labor Code gives five paid days for Lunar New Year, so avoid scheduling a production cutover for that week with a Vietnam-based developer.
.NET Developer Hiring Process
Second Talent's vetting covers stages 2 to 5 before you see a profile.
Stage 1: Define what the hire owns
List the apps in scope with their current runtime: .NET Framework 4.x, .NET 8 or .NET 9. Add the hosting (IIS, App Service, Functions or containers), the database and the date by which each app must leave an unsupported runtime.
Stage 2: Application review
We look for upgrades the candidate carried to production: the version they started from, the version they shipped, and what they removed along the way. A CV that lists each .NET version since 2010 without a single migration story does not pass.
Stage 3: Skills assessment
The candidate upgrades a small ASP.NET Core API from .NET 8 to .NET 10. The project includes a BinaryFormatter call and an outdated Kestrel package. We score the pull request, the test run and the notes on what changed for the people deploying it.
Stage 4: Live technical interview with a senior engineer
A senior engineer walks through a legacy Web Forms page with the candidate and asks for a migration plan: Blazor, Razor Pages or a rewrite behind an API. The second half covers Entity Framework Core queries that are slow in production.
Stage 5: Background and reference checks
We ask former managers about the candidate's last migration: whether it shipped on schedule, what broke after release and how the developer handled production access. You then pick the contractor or EOR route above.
